Hello.
I'm thinking about changing the PSU due to a weird hardware problem, and I'm wondering which one should I choose between Corsair AX1200 or Cooler Master Silent Pro Gold 1200W. Both are 80plus gold certificated and have cable management.

Plus a bit information of the weird hardware problem:
This happens randomly and not every time of system boot, the PC will run fine for around 10-30 minutes, but then suddenly there are no signal output to the monitor which will turns to a black screen but the most weird is the audio output will keep on going, the only way to get the PC runs property again is to force reboot by pressing the power for several seconds and press again. In personally I thought this is a PSU problem, but would like to hear what the others thought as well.

Thanks for the great help!

Official site of each PSU:
Corsair AX1200
Cooler Master Silent Pro Gold 1200W

Here is my system specs:
Intel Core i7 975
OCZ DDR3 PC3-16000 Platinum Series Low-Voltage Triple Channel 6GB
Asus Rampage II Extreme
Inno3D GeForce GTX280 PCI-E 2.0 1GB GDDR3
Seagate 640GB SATAII/32MB
Cooler Master RC-1100-KKN1-GP COSMOS Alu.
Cooler Master RS1250 Real Power Pro
LG GGW-H20L

AX1200, definitely.

It would be easier for us to help you out if you put in your system specs.

corsair.

it is the god of psu.

 

[tagurtoast]

also why do you need 1200W a good 750w could easily handle it. 1200w is enough for like quad SLI

Between these two, the AX1200 wins, hands down.

We still don't know about the new SeaSonics, which may best both of these.

 

[Inglewood78]

Hmm, it sounds like a videocard problem to me.

Your psu should be more than enough to handle you system. If you can get access to another psu, try switching it and see if that helps. I'd hate for you to replace the psu when its might not be the problem.

I'm planning to do a GTX 480 SLI or GTX 485 SLI.

a 750w is still good enough, 850w is ample too.

But isn't one GTX 480 consumes 450 walts at full load, so two 480 will be more than 900 walts?

No that is full system load, They use about 250w each.

I see. btw, are you sure a 1200W PSU can do a tri-SLI of GTX 480? Thanks.

Should why go for a tri sli though. From what I've seen a tri sli 480 uses about 1kw, but I can't verify how good their tools were though.

I won't have that much money too, I asked because I'm interesting about that.

 

[Eagle1337]

To clarify the answer to the question: yes a 1,200w psu should be enough to tri-sli.

[Witchdoctor]

For SLI 480's a 1200 is not really required here

the best 1200 out ATM is

I know many who have pushed these things to the breaking point and they have survived against all odds

Check out some reviews for yourself and see why this is the first choice for many benchers and enthusiasts

So RMA your card then? I don't think a new 1200w PSU is going to solve your obvious video card issue.
