Argh, thats really fustrating. I got this after filling an RMA ticket for the 430he with Antec:

"That motherboard requires a –5v. All of our current version 2.0 power
supplies do not have a –5v If you look at the main connector on power
you will notice that one of the receptacles has a empty slot. That
would normal have a white wire plug into it, and that would be your –5v.
This power supply is too advanced for your system. For a compatible. We
would advise using a standard version 1.3 ATX power supply that will
have the –5v."

That's funny seeing as how Antec lists this PSU as "ATX12V v2.2 compliant; backward compatible with all ATX12V systems." I'm pretty sure my MSI Neo2 Platinum is an ATX12V motherboard.

What is lame is that the PSU is failing on boards that don't require much power; that just blows my mind as to how ridiculous that sounds. Shouldn't be the other way around? Doesn't that piss you guys off? Imagine buying a new motherboard so it can be compatible with your PSU; it sounds ludicrous because usually you upgrade your PSU to match your high power components, not the other way around!

I mean i have MSI Neo2 platinum board, which at the time was the top of the line Athlon64 board (right before PCI express was availble), and now they make me feel like im living in the stoneage, talking about how my motherboard is not "advanced enough" for this PSU which is SUPPOSED to be backwards compatible with ATX12v systems.

Honestly guys, am I screwed? Is it at all possible to get this working on a board that needs a 5v? Or are they bullshiting me about this? Would putting all my components on a single 12v rail help in this situation?

And also, if I had gotten the good working version of this PSU, would it help things at all for my computer configuration? In otherwords, would persuing an RMA do anything to help my situation (assuming Antec agrees to send me another PSU)?

I know I am asking a lot of questions, but think they need to be clearly addressed, as I am sure there are many other people on this board with my situation; so thank you in advance.

**UPDATE**

Well it looks like I have found the answers to many of my questions

The Antec NeoHE 430 DOES work on my MSI Neo2 Platinum, despite what Antec told me. I just had to draw ATLEAST 1 amp from each of the 3 rails, like p-munkey alluded to (It wasnt clear to me on whether he meant all 3 rails or just 1 of the 12v rails). This is how i set my system up to fill in the 3 rails:

1st rail: Geforce 6800, which draws about 3 amps from what ive read
2st rail: the cpu, ram, soundcard, and motherboard was enough to fill atleast 1 amp
3st rail: hitachi 250gb Hard drive and dvdwriter was not enough to fill 1 amp, but when i attached the Antec tricool fan to it at medium, it was able to boot fine. I think adding an extra harddrive would also work.

This should help for those people who couldnt get the NeoHE to run on their computer because they were told that their motherboard "required" the -5v. I guess the morale of this story is, don't believe everything you hear from Antec tech support. First the about warranty label getting ripped during shipping and now this...

Case: Antec P150
PSU: Included NeoHE 430, SN/ S05110052xxx, Warranty sticker was cut
Motherboard: MSI K8NGM2-FID, BIOS 3.00 and 3.10
CPU: Athlon X2 3800+
Date of purchase: 2006-02-16

LEDs on kbd flash on power on. Fans run for a second, but no post (no beep, no video), then shut down. Turn the TriCool fan on full - the machine boots OK. :evil:

Update: Won't power on/post with two Samsung SP2504C and BenQ DW1650. Returned the PSU to the store and now I am waiting a new HeoHE. A "no name" 400W PSU, that I got from the store, seems to work fine. Also got a message from Antec support "Since you have returned the power supply to your seller let them know to make sure they send you the revised unit. Usually the serial number should start with 0512.".
Update II: Just installed the new HeoHE 430, s/n 05120165xxx with a little A3 at the s/n label. Works a bit better than previous one, as adding some old DVD and floppydrives to give a bit more load, NeoHE do power up when TriCool fan is set low. So I cannot say that fixed revision are really much better than previous ones; without some old junk hanging in the case my brand new PC won't power on.

What should I do now? Antec Rep, is it really so that Antec P150 with NeoHE 430 is impossible to use with MB that has integrated GPU and some HD & DVD that does not need much power?

Got mine with a P150 case, which I like a lot. Running it with an Asus A7N8X-X mobo, with the usual failure. Unfortunately, Antec tech support has a tendency to not reply to email (emailed [email protected] 5 days ago, no response yet). I'm giving up on tech support responding, I'll just get myself a nice Nexus 4090 and put this sucker in another machine for my sister, which will hopefully work. Very disappointing experience with their tech support, although the phone operator (who told me to send an email) was friendly, I'm not convinced by this company. Next time I'll also stick with buying seperate components (so seperate PSU from case) to avoid having to rip everything out to send the whole thing back to the store.

Hello, since Spain..

W.silentpcreview.com, is a fanstastic, web, and in power supplys the best...

W.storagereview.com is good too.

WEll, some people say me that power supplys runs, for 0.5 seconds, Fan etc.. and CRAHS for ever...

I BUY the First ANTEC Phantom 500W, in agost 2005, CRASH ins 2 days, install windows, etc.. conect all ans 7 fans... etc.. and crahs in runs, 0.5 seconds of ONs

I think I have a incorrec conections, but not see any error... ( devolutions to W.optice.es in Spain... very good service online shop..)

ANTEC soo GOOD, (garanty retuns if error previus 60 days.¡¡¡)

give me the money...

BUY OTHER PHANTOM 500W, in other shop ( I suspech anything..)


RUns okis... but have a lot of hot (noise not.) in (ASus+820D), I think the Case are small, Down the Vcore 1,235 and speed CPU to 2,6 ¡¡(auto it´s 2,8 Mhz) , yes more slowly.. ( have temps.. because Phatom hot, and not help whit the air hot... in case..

CRASH in 15 DAYS ¡¡¡¡¡¡¡, I´n very NOT unhappy, ( in my house family think I very stupid in do my PC ¡¡¡¡)

REturns to W.agalisa.com, (and this shop permit me change the product.. a lot of thanks. ¡¡¡) the distribuitor in spain returns other news for the shop.

I think in that moments, that 1,235 Vcore perphps not good, or 2,6 downclocking not good ( don´t understan anything ¡¡¡) , I think buy more Amp. in that moments ANTEC NEO HE, have 3 lines.. goods ¡¡¡

but... not in spain. in that moment

3 Power SUpply, I alsmost buy ANTEC NEO HE 550W, but in spain not can buy in october 2005. ;-(

I change to buy a SILVERSTONE 600W strike, ( more noise, but I modify it to runs more slowly, and add extern 8 cm Fans to help 12 fans power supply... both runs 7-10 Volts..., open, etc. (don´t care the guaranty, ..)


This power runs oks... The Volts variate more in loads, (Antec not variate the Volts...) but this not is a problem ¡¡¡ is good, because in MAX load the Vcores, and lines downs and temps downs tooo ¡¡¡

have four lines 16+18+16+8, 42 amp.. fanstastic.. and modular cables..
----------------

in resumen 2 ANTEC phantom 500W CRASH in my ASUS, not it´s posible a casuality.

Sorry for ANTEC, is good, but in this case not.¡

very good for 60 days returns ¡¡¡ guaranty.
----------

I see that the Phantom in Agoust,2005 have one PCIX, and not see the manual in box..., and the second phantom, have all manuals, have TWO PCIX, this not like me , because the designs it´s the SAME, wy in the same desings power have diferents PCIX ?

not like, not good, be CAREFULL....

-----------------
go to Nvidea, and see that certificate PCIX power supply, SILVERSTONE GO ¡¡

Other ANTEC true power friendly runs , but do a lot of noise..

I spoke too soon. Playing bf1942, ASUS PC probe complains about low 5V line with the 7800GT pcie plugged into the far right hole (away from the main cable). If I plug it in hole #2 there is no warning. So it seems like the combination of things you have plugged really matters.

Also watching the voltages with speedfan, it seems like the 3.3 and 5 voltages are low in comparison to a thermal take 430.

I just put together an Antec P150/GA-K8NF-9/GeForce 6500 system with two DVD drives, a floppy, two PATA drives, two SATA drives, audio card, LPT2 card and video capture card. Purchased at Fry's in Wilsonville, Oregon, 5February 2006. PSU Serial Number S05110063174. Connected to a Socket A board for about a week with the same peripherals (except the SATA drives) with absolutely no problems.

After installing the Socket 939 board on 12 February 2006, I could only start the machine about 50% of the time. Pressing the start button flashes the LED and bumps the fans but then the power supply crowbars. Cycling the power switch in the back will unlatch the power supply and pressing the start button may or may not start the PC.

Following some of the links in this thread, I tried moving the power cables around on the PSU and finally hit on the following, wacky, combination that seems to boot about 90% of the time:

(facing the front of the case from left to right)

1. One SATA drive
2. Empty
3. 2 DVD drives and floppy
4. 2 PATA drives and fan
5. The other SATA drive.

I specifically tried to move the DVD/floppy power cable to #2 and could never get it to boot. I tried removing the four pins off the ATX power connection (apparently OK from what the manual says) and this had no effect. I tried disconnecting the fan from the PATA drives and leaving it off. It booted every time(?!). I'm certainly not going to leave it like that! Putting the fan switch on high definitely helps but greatly increases the noise.

Oh, and I'm sure the cardboard box the case was in had never been opened but the power supply warranty label is clearly broken.

I will never again buy or recommend Antec's products. No power supply should be this sensitive and their lack of response is beyond understanding. I'd take it back to Fry's if a) I didn't have so much time invested in it already, b) the return line wasn't a mile long, c) they'd take it back without taking twenty minutes to test it and d) it wouldn't take me a couple of hours reassembling a new machine.

At least the NCQ problem in the nVidia SATA RAID (also took several hours to research) was easier to fix. Turn Command Queuing off...

I have bought an Antec P150 and installed motherboard, drives and graphics adapter. It's been used for the last 10 days without any problems.

PSU S/N: 05110060411
Date of purchase: 12. february 2006

Motherboard: Intel D915GAG - micro-ATX board with Pentium 4, 3.0 GHz Prescott.
Graphics adapter: Asus Extreme AX300
HD: 160 GB Seagate SATA.
CD/DVD: Lite-On something
CPU cooler: Scythe Ninja running passive.
Tricool set to low.
A 92 mm fan in front.

Not a lot of hardware in that big box.

No problems with the PSU. It boots every time. No unexplained reboots, crashes or blue screens.

For testing I had it running CPU Burn together with a antivirus scan (Zone Labs), which results in a CPU-load of 60-100% along with a lot of harddisk activity. This has been done a few times. No problems.

After 30 minutes of activity the CPU temp. rises to 65-72 degree C.

When idling (or doing office work) CPU temp is approx. 45 degree C.

But... What will happen if a change the motherboard?! Will the PSU still work?

I purchased a Neo 550 at CompUSA - the supply was dead on arrival so I returned it and got a new Neo 550. Second one worked for two weeks and failed. I returned it and got a third supply. The third one was DOA. I thought that the problem was an incompatibility with my Asus board but the when I tested the second and third unit with a Power Supply Tester, they were completely dead.

NeoHE 380 failed after 2 months

Posted: Tue Feb 28, 2006 6:10 pm

Hey! First post here.
  • NeoHE 380
    Bought in late December 2005.
    S/N: S05090011038
    MB used: Dfi Nf4 Ultra-D
    MB verified: Abit KN8 Ultra
I've got a NeoHE 380 that failed on me yesterday. It had been rock stable and silent as a whisper since just before last year ended. I was doing my regular session of WoW and my computer suddenly just turned off - when I tried turning on the power again all that happened was that the fans (CPU, chip & 2x120 mm) started spinning. The diagnostic LEDs on my mainboard lit up as well. These made me believe that somehow my MB had borked on me so I went to Dfi-street.com looking for people experiencing the same symptoms as I. There was quite a collection there and many answers were about the PSU. I, of course, shrugged the PSU-failing off as a possible answer since my PSU is new and über. Little did I know that there was a ton of people out there having problems with the Antec NeoHE series...

Anyway, I collected the CPU/MB/RAM and PSU and went over to my GF's sister to try troubleshooting my stuff. Turned out it was the PSU after all - I also verified it by connecting my PSU to their MB (also NF4, but Abit), it didn't start except for the fans.

What troubles me right now is that I haven't read about anyone else having a NeoHE for 2 months before it died - everyone seem to have either good or bad from the beginning. :cry:

I guess I'll call the retailer tomorrow (dataparadiset.com) and see what'll happen. Gah, I hate trouble such as this.

This adds a whole new dimension to the problem. Maybe there should be a new poll - "If your neohe was initially compatible, how long was it until it became defective?"

Could you elaborate a bit on what you learned at DFI-street? Are there lots of people whose power supplies have failed, or are is it just like here and there are a lot of people experiencing shutdowns. By "failed" I mean it worked (even if only intermittantly) before, and now will not power anything.

Also, was there any link between people having compatibility problems (as are talked about all over this thread) and having the PSU fail? I think frankgehry is jumping the gun a bit with his assumption here, since you're just one user, but I would like to know more.

All I could find at dfi-street.com concerning the neohe was an emphatic "NO!" and "Known Issues. NOT recommended." from davidhammock200 (1-15-2006) when responding to requests for neohe recommendations.

http://www.dfi-street.com/forum/showthr ... e=82&pp=15

I just noticed that the neohe 430w was placed on the retired recommended psu's list. I'm not sure it really belongs in the same category with other reliable psu's like the enermax noisetaker and the seasonic super silencer.

"Retired until proven reliable. 01-03-06" - that's a tall task.

Nevertheless, the torrid thailand neohe 430w/p150 build article was posted on 01-10-06.

I've also posted about erratic behaviour, in this thread:
http://forums.silentpcreview.com/viewtopic.php?t=25890

On 5 February I reported that a new build started to malfunction (not starting up) after a couple of weeks. I opened a new trouble ticket at Antec and they asked me to test the effect of adding extra fans. I did this, but the results were inconsistent - sometimes it starts, sometimes not. Moving the cables between sockets on the PSU also, sometimes, gets it to start. Whatever the problem with these early NeoHEs, the effects have a degree of unpredictability.

I've asked Antec finally to give me an RMA, and now I'm waiting patiently for an answer.

My PSU has s/n 0509000XXXX.

I didn't read about anyone actually having a NeoHE (on dfi-street) and that's why I never really suspected my PSU to be faulty (until I tried it). I also did no search on "NeoHE", just the symptoms with fans running and diagnostic LEDs being active.

I'll assemble my computer now and try to crank up my case fans to see if there's any effect from increased power demand (got 2x160 GB HDs, X800XL and 2xOptic drives except the case fans). When I assembled my system the first time I tried to even the load on the different rails and perhaps I can try to put more draw on just one rail as well.

I don't really see how the PSU could just suddenly decide that it needs more power draw to be able to start up after 2 months of usage, though. Worth a try before I call for RMA, I guess.

There are many variables at work here - the amount of current needed by the PSU to push it over a threshold, and the amount of current drawn by several different components of the system (mb, drives, fans...). A tiny variation, perhaps linked to the ambient temperature or the even the state of the system at shutdown, could mean that the balance shifts from day to day.

I've noticed that the failure to start is generally evident if the system has been switched off overnight. Once the system is started on a given day, it can usually be restarted with or without extra fans, shifting cables to new sockets, etc.

NeoHE430 DOA; RMA'd PSU; New one works with my ASUS board

Posted: Wed Mar 01, 2006 10:34 pm
by geohec
In January, I bought the Antec P150 with NeoHE430 at Fry's in Sacramento, CA. When I got it home, I built a system with the ASUS A8N-SLI Premium MOBO. Like many others, it spun for a few seconds then died. The seal on the PSU were not ripped so it was a virgin (S/N S05110062XXX). I plugged in an extra PSU that I borrowed from a freind (and it worked fine). I finished my system build in a day or two and I was ok with this since I new of this potential issue with the PSU (just hoped it wouldn't happen to me). The case was sturdy well thought design and great cabling. Only complaint about the case was I had to take out the MOBO to get the PSU out since I installed the CPU with my massive heat sink before the problem occured.

Getting the RMA took a little bit of work. After a week of waiting for Antec to issue me an RMA number, I decided to call them and check in to see what was up. They said they sent me an email with an RMA number, but I never actually received one. So I got the RMA # from the guy on the phone and I RMA'd the PSU ($8 out of my pocket :x ) to Antec the next day. The guy from Antec was nice enough (out of the Fremont, CA) HQ office, but he said that they were having a big computer network problem at the beginning of the year and they've trying to remedy their problems ASAP. They been focusing/prioritizing on RMA products coming in and trying to get them out ASAP, but other things like double checking that RMA number were getting out have slipped here and there. The guy sounded nice enough and sincere so I didn't rip him a new one, I figured $#!^ happens. Just make sure your persistent if your in the process of a return.

After about 8 days I got the new PSU in the mail. It was a new boxed retail version of the NeoHE430 (S/N S05110077XXX) still in the wrapper. I plugged it in and it worked great. I have had this system working 24/7 for about a month now. I put the system through some stress tests (macros, video rendering, etc). I'm not a hard core gamer but I ran a few games on it with out much effort.

The PSU runs very quietly as stated by SPCR. The loudest thing in my system at idle is the 120mm stock case fan in the back of the unit, but even that is whisper like and quiet. I'm very impressed with the PSU and P150 case. The PSU has NOT had a glitch, random reboot or a blue screen of death. The case with a working PSU is a solid performer and great buy, if you have the patience to deal with a possible return.

I've read some posts about possible PSU melt downs after weeks or months of operations. But after a month, I see no signs of that. If it happens I have a 3 year warranty to fall back on or I'll just get a seasonic if I have the spare cash laying around. Good luck. 8)

Latest instalment in the my attempt to get an RMA: this was yesterday's message from Antec Customer Support:
"The NeoHE has a newer design which is the ATX12V v2.2 and when using older motherboards it might not work properly. The NeoHE will work with motherboards that requires the ATX12V v2.01 or higher. One thing you can try is to have everything installed or install additional fans in your case. Otherwise this power supply is too advanced for your system. For a compatible replacement, you might want to take a look into our True Power 2.0 series. With that said, replacing the power supply with the newest revision you have heard about, we are unable to guarantee this will fix your problem."

I replied that my second motherboard (ECS 760GX-M) was brand new and it's a current model which - as far as I know - should require an ATX12V2.01 PSU. So let's see what happens.

Otherwise this power supply is too advanced for your system.
I see Antec are still continuing to give BS (and insulting) responses to RMA requests. They seem to think the mushroom method will make the problems with the NeoHE go away (keep customers in the dark and feed them sh1t).

That's exactly my experience. From a cold PSU, it takes a couple of mains switch cycles to get going. From then on, it'll start reliably as long as the PSU is warm. I've tried adding and removing loads and switching cables around but nothing will get it to start cold.

A8V + NeoHE 430 = OK

I picked up a P150 in Fry's (mistake -- much cheaper on NewEgg :-) for my Asus A8V motherboard. Thus far, the included NeoHE 430 works fine with the A8V. I don't have the PSU's exact serial number handy, but it begins with S0511, and the warranty seal is broken.

Antec NeoHE 430 - SERIAL NO. S05110048031.
And the Warranty VOID sticker is broken from the factory.

I just put together a system with the following:
  • Antec P150
  • ASUS P5LD2 Deluxe BIOS 0312 upgraded to 0506 in the hopes of fixing the issue.
  • ATI ALL-IN-WONDER 2006 Edition X1300
  • Intel Pentium 4 630 3.0GHz 800MHz FSB Prescott w/2MB cache
  • Corsair XMS2 PC2-5400 1GB 2X512MB DDR2-675 CL4-4-4-12
  • Thermalright XP-120
  • Seagate Barracude 250GB 7200.9 (x2) - RAID 1
  • Seagate Barracude 80GB 7200.9 (x2) - RAID 0
  • Pioneer DVR-110D DVD-RW
  • LiteOn DVD-ROM
  • 1.44MB White 3.5" Floppy Drive
  • Nexus 92mm (x2) - front intake
  • Nexus 120mm - CPU fan
  • 5.25" 7in1 Flash Card Reader w/USB Ports
  • Microsoft Comfort Curve 2000 Keyboard
  • Logitech MX1000 Cordless Laser Mouse
  • Windows XP Media Center Edition 2005
I hooked everything up, and had it all nicely tucked in and powered up the system. Guess what? It didn't work. The keyboard was hooked up via PS2 and the Num Lock / Scroll Lock / Caps Lock keys would just flash in a repetitive manner. I tried stripping the system down to just the CPU, motherboard and PSU but the system still wouldn't react any different.

I took my Antec TP2-550EPS12V out of my dual Xeon machine and hooked it up to the system and voila, everything worked beautifully. Just as I would expected it to. I then flashed the BIOS from 0312 to 0506 in the hopes of that maybe helping, well it didn't. I also tried plugging in the ASUS EZPlug hoping that would help, nope.

Sadly, I had read through this thread before ordering, I was just hoping I wouldn't have the issue. Guess what? I did.

Looking at this thread again feels like an I told you so.

Despite the warnings in these fora and others I decided to go ahead and buy the Antec NeoHE 500 for use in my new system:

Asus A8N-SLI Premium
Athlon 64 3700 (San Diego) with CoolerMaster Sussuro HSF
1 x eVGA GeForce 6800 GS (OC'd by manufacturer)
2 x Seagate 7200.9 SATA-II 160GB HDD
1 x Maxtor DiamondMax 10 SATA 80GB HDD
2 x optical drives
Antec P180 case with 2 of the 3 stock fans connected, both set to Low

The Antec NeoHE was exactly what I wanted for the system. I figured that if it didn't work then my good friend (who designs PSUs for a living) would be able to fix it for me :D

I needn't have worried - it worked perfectly straight out of the box. I tried it first with just the mobo, CPU + HSF and the gfx card and it booted up fine (as far as it could without any drives at least). I didn't wait to see how long it would stay stable. I installed the rest of the components, booted it and it's still running 4 days later.

The PSU was bought off-the-shelf at Central Computers in San Francisco and has an 0512... serial number. The warranty sticker is folded over an edge but it was intact.

[OT: I'm very happy with this setup. All the components are pretty quiet and I really only notice noise at night when the apartment is quiet and I sit next to the PC, and even then it's only a low whipser. The case is very good and not that tricky to build. I bought an ATX PSU cable extension set but ended up not needing it with careful cable routing.]

I also have a NeoHE 430 mounted in an Antec P150. The warranty sticker is broken.

Everything works, but the PSU is quite noisy (probably the noisest fan in my system). It starts out very quiet, but after about a minute, it ramps up and starts making noise. (See this thread.)

I don't have a very hot system (board temperatures are around 25 C and CPU temp is around 35 C, its an AMD XP 2GHz), and I tried insulating the PSU from the CPU cooler with a rubber mat, but it still starts blowing lots of air soon after I power it on.
