Sounds like a video driver problem, or an unstable GPU overclock. Bring the GPUs back down to stock speeds and see if the problem still occurs.
Corsair TX850, biting the dust?
First check sig rig...
I can't seem to be able to play crysis anymore, at least not for any length of time, after about 15-40 minutes of gameplay the screen goes black, all video feed from the computer is lost, and the sound continues to loop in the background, computer is completely unresponsive inluding things like the caps lock key.
This happens mostly in crysis and occasionally in other games, GPUs and CPU are under water, all temps nominal. Have been running stable overclocks (prime95, furmark, 3dmark) for almost 5 months now, so no problem there. The only recent change has been the addition of water cooling and several accompanying fans.
So my question is…
Are these random shutdowns a symptom of a failing power supply?

I would have gone with the GPU or RAM failing, seeing as the computer continues to run, admittedly locked up, but you lose video feed. This could be caused by the memory overheating on the GPU.
Im sure more experienced users with the Nvidia can comment. I've seen this with my ATI and that was caused by too much overclocking on the RAM and it getting too warm.

It's hard to say, but you could probably start testing the problem with only 1 gtx 285 and 1 memory slot used, and than 2 different, and 3 and so on....disconnect those fans just for testing purposes...
A bit more expensive solution-> get different PSU from your friend or buy one if you can return it and find the solution.
GOOD LUCK

The symptoms you described are exactly the same as mine when my old power supply died. It would lose all video and have a constant sound loop or once in awhile it would BSOD. we changed, ram first, that wasn't it, video card, not it, finally ram and mobo before we tested the psu and it was dead.

Its been stable for months before this (on air), crysis benchmark will run for sometimes over an hour then....poof, nothin'
Video drivers are the latest from EVGA, have tried dropping core, shaders, and memory by 10-15 mhz, didn't help one bit, but I shouldn't have to considering it was fine a couple weeks ago.

If its running prime etc and not failing, but only in games then i'd not be questioning the PSU. Drivers or GPU / RAM overclocked.
Other than that, as others have suggested, try another PSU, but the 850 will run all them components easily.

Sounds like the psu is dying, i had the same problem when i was running my 9800GX2 on a 400w generic PSU, in GPU intensive 3D games the monitor would go into standby and a continous loop will output through the speakers.
Try running 1 GTX285 and using different drivers, see if that would work first before buying a new PSU

Using everest I found that all the temps on the GPUs were fine, memory never rose past the 50s. I have full cover passive aluminum HS on the cards, but they are kept cool by the massive 230mm fan in the HAF 932s side panel
Prime runs overnight on the large ffts so I don't think its ram...guess I'll have to take apart my PC when I just got it back together...

Ouch .. .. Don't you just hate surgery.
There is nothing worse .. Good Luck dude..

What you're describing happened exactly to me with my 5870, while gaming under load. Usually 15-30 min in. Screen would go black, sound starts looping in the background, computer unresponsive, inevitably freezes, etc. Other times computer would just power right off. Was on an Ultra X-Finity 600w while it would occur. Blamed the video card as the culprit... until I replaced the psu and bought a Corsair TX650w. Hasn't happened since. So, I'd say those are prime examples of a psu starting to fail. ...Or video card.
Thanks for the quick replies, will have to start disassembling when I get home, luckly I have a HIPER 880 watt that I can try out.
Happened to me with my old system when my enermax died.
It could be that your PSU may be a bad one. I guess its just bad luck.
Contact Corsair here and they'll sort the problem for you.
Good luck!

Thanks guys for all the input, (+1 to all)
Think it was the GPUs over all as I tried varying speed fans directly on them, when using the higher speed ones the system remained stable.
Guess thats what I get for not going full cover on my water blocks (sigh*)
