What's a good silent 400W PSU that is high quality?

Post by Happy Hopping » Sat Jun 01, 2013 3:10 am

I am leaning on the EA-380D or EA-430 from Antec. However, their EA-650 review make me pee my pants: 44 bad review of it caught on fire.

So I was thinking of trying Coolmax ZU series, it's very quiet, but the review shows a lot of them pops after a few mth. of usage:

And yet, their Coolmax ZX series has good review and it's cheaper

and I don't know how much wattage I need on these PSU, as I sell quite a few of them, it's the Gigabyte

connects to 1 DVD burner, and 1 x SSD.

I am sure the 430W is enough, but how much do I really need? Can I go down to 380W?

Assuming in the future, some of them might need to add a 6 pin PCI E powered video card

Seasonic G 360.

You don't mention the CPU, so let's assume it's a 77W Ivy Bridge. Your system's stressed load power will be under 130W.

http://www.silentpcreview.com/Nexus_Value_430

I've been using one since 2010 and I'm still very happy with it.
you can also find it in the table of the article that was linked to earlier
http://www.silentpcreview.com/article1297-page4.html

Seasonic G360 is very loud by comparison.

Sadly the Nexus was discontinued and is now hard to find but there is currently a sale on Amazon:

I think it's CPU 2 x 4 pin, it says that on their website, although I like website that clearly shows a photo of the 2 x 4 pin connectors, that way, I know for sure.

I won't mind knowing the dB of their fan, even it did say "Smart & Silent Fan"

How come this new G series is so inexpensive? It gives Japanese capacitors tested at 105 deg. C for the street price of $59?

anyhoo, that's great find, thanks, I'll go with it

Blubberhoofd, I think Nexus is only 2 yr. warranty vs. 5 yr. by seasonic

From the JonnyGuru review has written 4+4 pin EPS/ATX12V, and even though the photo is not that big, i see the 4+4 next to the 24pin.

thanks. The system I'm installing weekly compose of:

1 Pentium G2020, 4 GB of RAM
gigabyte B75M-D3H motherboard

http://www.gigabyte.com/products/produc ... id=4150#ov

plus 1 x SSD, 1 X DVDRW

So w/o using the PSU calculator, I would agree that 360W is enough

IN the future, there is the possiblility of a GT video card for those who seriously need 1, using 6 pin PCI E, but that would be rare, not to mention the PSU does support a PCI E 6 pin plug anyway

I built a system with the exact CPU, a B75M-D3P (should be close enough), 8 G ram, spinny HDD, optical drive *and* a geforce 650. It's running on a Seasonic G360, draws 45 W at idle and maybe 110 W in gaming load. Basically any quality PSU you can buy is overspecced :)

Another data point for the OP: Core i7 3770K, 16 G ram, 2 spinny HDDs and a GeForce 660 draws 70W-ish in idle and 170W-ish in gaming loads.

I just re-check the spec. of the Seasonic G-360, its dB level is 22 dB. How quiet is 22 dB? I know with 12 dB on a cooling fan, you can't hear it. So what about 22 dB? Can any1 gives me an e.g. of 22 dB is like?

Also, is there a wide range of quality control from this brand, as I read this:

http://www.newegg.com/Product/Product.a ... llFullInfo

some said it's quiet, some other said coil whine. ANd I have read other seasonic PSU, they also complain about coil whine.

Can I assume if my load (the above configuration) is so low, that I shouldn't need to worry about coil whine? Or is seasonic quality control has such a wide swing that you'll get coil whine depends on what batch of shipment you get. Which is it?

Alternatively, wouldn't this be better?

it's the Enermax NAXN 350W to 450W PSU

I have a seasonic X660 and X400 and both are fine no coil at all. I just did a couple of builds with Seasonic G550 no coil either. My guess is a combination of hardware that does it, and seems more prevalent on seasonic than other brands atm. Still its not an issue for all, but if you want to avoid it, you could go with Rosewill SilentNight-500, reveiwed by SPCR also, Rosewill Silent Night 500 Platinum 80 Plus, its the same as the KINGWIN STR-500 Stryker Fanless Power Supply and has great user review also.
