Any Modu82+ 525w update?

DeltaForce · Post by **DeltaForce** » Wed Mar 26, 2008 11:04 am

I need a new PSU soon, and the review of the Modu 82+ on this site persuaded me to go with it. However the review mentions in the conclusion that the sample 625w PSU was the only one tested and that more would be coming in a couple weeks, including the lower watt versions.

a) Has there been any update to this?
b) Has the 525w version been listened to by silentpcreview yet, or by anyone else? While it seems likely it would be just as quiet as the 625, it would be nice to know for sure before buying it. For example, Michael Sandstrom said in previous thread about the Modu425w, â€œBTW, The fan in my PSU had an audible rumble that's annoying.â€

Hi, you might like to take a look at Anandtech review of Pro82+ 385 & 525w and Modu82+ 525 & 625w PSUs.
My quick summary: Efficiency is similar across all of them, the 525w appeared to beat the 385w at all levels, inc very low wattages. EDIT for 240v AC, for 110v AC their tests show the 385w having small advantage up to ~100w
Also it (the 525w) only spins it's fan to max of 1300rpm vs 1500rpm for the 385 and 625w versions. Why the 385w should need to get to the same fan speed as the 625w I'm not sure, I think one of the heatsinks is smaller which may partly explain it. Either way none start to ramp the fan up until ~50% load, in the 385w PSUs case that's ~200w. My PC will get to around that level if I over-clock the E6600 CPU (2.4GHz) to 3.5GHz (inc the Vcore increase this probably DOUBLES the CPU power usage) and load it and the Radeon X1950pro fully.
In other words most systems won't tax the 385w version and it's significantly cheaper.
Pro82+ Â£43 vs Â£52 vs Â£70 vs Â£90 (385w, 425w, 525, 625w)
Modu82+ Â£60 vs Â£76 vs Â£105 (425w, 525w, 625w) [from www.scan.co.uk]
Hope this helps, Seb

For a UK comparison should I be looking at the >230 VAC (we use 240 here I think?)

I have the 625W version (running at 471 RPM at the moment). A bit OTT but I wanted something quiet now as I was building a new system (and there wasn't any reviews of the 4xx/5xx versions!).

I can't give you any noise comparisons as I am using the stock intel fan (ouch) and stock P182 fans (ouch!) until the replacements come. So they drown out anything.

SebRad,

That was a helpful post, and I have decided to go ahead and get it. The review you cited had silentpcreview's good conclusions, at least at this point in time for the Modu -which is a new product.

One last question, and it is probably a meaningless one, but the Modu specs says it has the latest ATX12V v2.3. Is the PSU being compatible with version 2.3 going to cause any problems if I put the PSU into my 3 year old system? I am assuming not because it is the same voltage, but just wanted to be 100% sure.

Thanks.

I installed a Modu82+ 425 watt in a four year old system. There is no compatibility problem and the units are also designed to work with inexpensive simulated sine wave UPS units.

I am satisfied with my new Enermax but my fan is not as quiet as the one tested in the SPCR review.

I think it is fiendishly hard to "tune" the volume and equalisation on your PC to evaluate the SPCR samples fairly. So, perhaps you can say whether the unit you received is also louder than the competing samples from the SPCR review at the same settings (as I understand it) as when you play the SPCR sample for the Modu+625?

thx in advance

I just installed the Modu82+ 525 in an Antec Solo and, fortunately, it is as quiet as the the SPCR review indicates -- totally silent.

The reason my Modu82+ 425 watt was louder than the 625 watt unit tested by SPCR was a faulty fan control circuit. In my low power system the fan would idle at 650 rpm, a speed much higher than the ~480 rpm reported by many Modu82+ owners. I RMA'ed my faulty unit and ordered a replacement.

Please, when you recieve your replacement report it to us. I'm thinking about getting a 425 modu82+ enermax too

I've got the Modu82+ 425W that I won from the draw. Next to the Scythe Slipstream 120mm fan in the Antec Solo, turned down to ~730rpm using a Fanmate, I can only hear the Scythe and not the PS.

However, I'm trying to read the fan speed of my Modu82+ 425w. Using it with my Asrock Conroe954G-DVI, I can't read it off neither the CPU nor chassis fan headers. The Scythe SY1225SL12M fan is detected on the CPU fan header. Any ideas why the PS's fan can't be read?

Hello Lucky,

I would not stand for a problem like that. You should definately ask for your money back. Oh right, you didn't have to pay anything.

To get serious, I read my Modu82+ fan speed off the chassis header of an Asus K8V SE Deluxe MB using Everest Home Edition (free at File Hippo). I had to temporarily disconnect my chassis fan to free a header for checking the PSU fan speed. Although my MB has three 3-pin fan headers only two of the headers function. Even when the MB was brand new the third header would neither power a fan not read rpm. I considered exchanging the board but I kept it because there were no other problems.

I think you should be able to read the PSU fan speed if the same chassis header will read other fan speeds. You might want to contact Enermax if monitoring fan speed is important to you.

Thanks for the update!

Thanks Michael. I thought about raising hell with Enermax, blasting them on various forums including this one, but looked at my credit card statements and couldn't find the line showing my purchase and smiled.

I've tidied up my cabling inside the Solo, but I bought a bolt-thru kit for my Ninja so I will try when I install that. The CPU fan header is a 4-pin header that I current use with a Fanmate for the Scythe case fan. The chassis fan header is a 3-pin one. I'm pretty sure the chassis fan header could power up and read my Noctua fan in my previous setup, but I'll confirm.

I RMA'ed a Modu82+ 425 watt PSU which was relatively loud with a beginning fan speed of 650 RPM. I decided to order another unit and hope for better results. I just hooked up the new unit and it is very quiet with a beginning fan speed of 463 RPM. The previous lowest fan speed I have seen reported was 479 rpm. Power usage readings with a Seasonic Power Angel show considerably reduced draw compared to my old Seasonic SS-400.

Any Modu82+ 525w update?

Any Modu82+ 525w update?

is the fan louder than the other comparisons?
