PC Power & Cooling S75CF or CORSAIR CMPSU-750TX

PC P&C
Corsair

Looking at purchasing a PSU for my storage server. Was planning on getting a 750TX, but then this hot deal for a PC P&C 750 pops up, $60AR. So I could save $40.

Both have 60A on the 12V rail, PC P&C has 30A on 5V rail, Corsair has 28A.

Which is a better PSU?

Both are very good... But the PCP&C uses a 80mm fan compared to the Corsair. Then again, it's cheaper!

Well, I ordered the PC P&C Silencer 750W CF edition PSU. Can't beat the price AR. Hopefully mine wont have the same problem that the other fellow did.

21 HDDs??? nice

do hdds use the 12v rail now or 5v like the past?

let us know how it goes

My PC P&C Silencer 750 arrived not working quite right in that my machine started acting extremely flaky after installing it. The PSU is longer than standard so I actually had to pull my Icy Dock out for it.

Yeah awesome PSU's. Just got one 2 days ago and it supported much more than its labeled 750 watts

I believe they use both rails.

This is often true for a lot of good PSUs, they're rated for a specific ambient temperature and if they're kept cool they can output more than the labels rated power. Silencers are rated for X watts at 40C. Some other brands are even rated for X watt at 50C.

You've got 21A @ 12V running and up to 42A @ 12V of starting current, so you'll want to have some system that stagger starts your HDDs as you won't really get the specs you think unless the other voltages/rails are lightly loaded. 60x12=720W so not much left for the other voltages - this means you'll never see those 60A except in bench-test circumstances.

Just playing devils advocate here...
So are you saying that bench tests can be misleading?
