There are three different cooling schemes:So the venting on the Seasonics might well be superfluous, if the Corsairs can do without??
a) Seasonic S12 with very quiet fan and venting holes on the back;
b) Seasonic M12 with additional 60 mm fan on the back;
c) Corsair without 60 mm fan and venting holes, but with more powerful (and more noisy) 120 mm fan.

HX620W model.... basically, this model has the same accoustic properties of the 520 version except that it can handle higher loads correct?
HX620W is my next psu for the new r600 ati cards that are comming out. hopefully, like usual, the all-in-wonder versions require less cooling (like my x1900 aiw is much easier to cool than the xt version non aiw)

Hi
Im looking for the quietest power supply to buy, and after reviewing the tops chart @ http://www.silentpcreview.com/article699-page1.html Im wondering why is Corsair HX520 rated 8+ in the noise department, and Seasonic S12-430 only 8 when in their reviews HX520 produces 22 dB(A) of noise and additional noise at lower loads, and S12-430 only does 20 dB(A). Another weird thing is that while hearing the recordings, i find the S12-430 to be louder than Corsair despite their measured dB(A)s . So, which one of these 2 PSUs would you recomend for my "silent workstation" based on a Intel G965 motherboard (with integrated Intel X3000 graphics), a Pentium D 820, a couple of hard-drives and an optical drive in an Antec Solo case? I don't want to be bitten by buzzing sounds from the Corsair PSU at lower loads, tough it seems quieter overall.
Cheers

My current PC has been crashing alot, and now won't even boot (using the Antec 380watt PSU in the NSK4400 case). I'm hoping it's not the motherboard, and so have gone for one of these Corsair 520watt PSU's - hopefully I'm replacing the right part, but either way, looks like I've picked a decent PSU!
You've pretty much answered your own question - the ratings are based on how audible/noticable the unit is to a human ear, which is not always the same as the db(A) rating.

The only difference is the "EU", which means they're the European model386-sx-33 wrote:Corsair CMPSU-620HXEU, 620W (ATX12V v2.2)
Corsair CMPSU-520HXEU
I can only find the above PSUs.
Their modelnumbers are slightly diffrent from the ones in the PSU.
Are it the same ones as in the review that's 7 months old now.
there are 3, EU, UK and US, the only difference is the type of plug that is supplied, the internals are designed such that it will recognise any type of voltage is being input and switch accordingly.386-sx-33 wrote:Yeah, I guessed that much
But it also means its a different model.
Most likely there are no performance differences; but lets say I've gotten over cautious over the years...
Fan swap possible?
Hi guys,
Does anyone know if it is possible to replace the fan of one of these corsair units with any other one?
I mean, is there any two/three pin plug inside the psu, or otherwise the fan is welded to the pcb?
Thank you very much!

In S3 sleep mode, the PSU fan turns off, at least it does on the systems I've built that do S3 (SU380 x2 and neoHE 430). My system with the corsair 520 doesn't really do 'off', in any variant, so I've never tried that one, but I suspect that it, too, would completely shut down the fan in S3.
And without the fan running, most PSUs are completely silent (not entirely self-evident, the transformer can hum a bit in some of them -- not on the ones rated highly by SPCR, though).

After reading nothing but gold reviews from just about every major hardware site and Newegg's comment section, I finally bit and got the 620w. I plan on doing some overclocking so clean, reliable power is key. Hopefully the unit I have will be up to the task. A five year warranty even tops my Antec True Power 3 year. Not bad! I powered on the the new PSU with the old paper clip trick just to see how loud the fan was without connecting any other noisy parts. At no/mild loads it is nearly inaudible at a meter away. Great unit!
