Pc shuts down when playing on 3 monitors

[Chill1100]

I just recently installed another GTX 770 for sli and whenever I try to play an online game with nvidia surround my pc restarts? I think it may be a psu problem.

i had this problem and it was related to ram, try to run memtest and see how it goes, and yes it might also be a psu problem.
Have you checked temps when playing games? maybe some components are overheating.

I've checked temps gpu 1 will run 50 - 60 Celsius gpu 2 will run 60 - 70 Celsius
It might be my ram as I'm currently running corsair vengeance with Kingston HyperX beast

Sometimes mixing ram from different manufactures can cause problem, so try taking out the Kingston ram and only run the crosshair ram then see how it goes.
Also Is anything in your system overclocked? Overclocking can sometimes cause systems to become unstable

Both gpus came factory overclocked but other than that nothing has been oc'd

Also just FYI I can play games fine on 1080p ultra setting just whenever I go to 5780 my pc restarts. I can use programs like photoshop and cryengine without problems and my system recognized and synced the speed of my dram

Il try taking out the Kingston and see what happens

Tried removing the Kingston ram but same issue I think it's the psu
Tried playing game just with one monitor and I can play it with no issue

 

[PlasmaScopes88]

hmmm, sounds like a software issue now.
Try updating or reinstalling drivers.
what games are you trying to play? Maybe the game doesn't support 3 monitors.

Did you re-enable sli? You need to do this when you reinstall drivers.

Yes I went into nvidia control panel and activated sli. I'm now just running on one monitor and everything is fine I don't get it and I really hope it's not the psu I've just spent 400 bucks on a gpu!!

What PSU is it specifically?

Also a new gtx770 can be had for $320.

[Chill1100]

Yea I got the GTX for 330

My psu is a ultra professional HS 750 hybrid atx power supply 80+ bronze

There is not much info about that PSU, but seeing as how it only costs $70 and is modular and 750w, I doubt it is good at all. It is probably among Ultra's low quality units. It also only makes 16a on each of the 4 12v rails. This is pathetic for a 750w unit. My 750w Antec makes 40a on each of the 4 12v rails. This could be the problem. Replace it with a quality 750w unit from Antec, XFX, Seasonic.

 

[Chill1100]

Should I go with an 850 or a 1000? I found a cheap 850 at bestbuy the thermaltake m850w smart for 119

 

[Chill1100]

Is 750 enough? I took a psu test online it told me I needed 1100w? Crazy

 

[tiny voices]

750 is fine for your build, it just needs to be a quality unit.

No, I would not recommend Thermaltake PSUs.

No, that test lied. 750w is plenty. I SLI'd 570s on 750w (a 570 uses WAY more power than a 770 does) with no issues for like 2 years.

How about corsair psu's

The closest tigerdirect is 45 min away and bestbuy is ten seconds and they have corsair and thermaltake but if they're shitty just let me know
