I cant figure out why my computer is crashing when I sli my two gtx 580 cards. The PSU I have is 1350w and reviewed very well on this site. Both cards
play well on their own it's just when I sli them it crashes in the game I'm playing and the game my son is playing. I dont have another high wattage psu to
see if it the problem. I have a 600w sitting around I just dont it will do the job as a test replacement. Any ideas ? Thanks.

Have you checked the cards in the second PCIe slot?
Does the issue occur only when gaming or can you not even boot?

When you say it crashes what does it exactly do?

Does it close the game and go back to the desktop or does it blue screen?

Need more info about the nature of the crush and you should analyze the dump file (if there is any).
And please also mention the version of driver that you are using.

Have you tried a different sli cable? I had the same problem before and switched out the cable and fixed it.

What happen is when you try to play a game the computer just reboots. Its fine other wise ,when theres no demand on the system. I have tried a different sli bridge cable and tried swapping the the cards in the slots their in .
The computer is not OC,ed currently so thats not it. It seems like the power supply to me. I hope not.

Have you tested a single card in the second slot only (leaving the first slot empty)

Have not. I will give that a try. I didn't know you could get it work like that,second slot only.

It depends on the motherboard, I know my motherboard will support a single card in either slot, but by all means give it a try

Well it's working in the second slot. Now for some testing. Thanks for the suggestion BTW check out this psu from evga http://www.newegg.co...N82E16817438004

Well if you want to buy me a present...

Only kidding - I was going to suggest though you could (possibly, entirely at your own risk) raise the PCIe clock by 1 or 2 and that could resolve some issues, however be very very careful

Thats something to consider. I was able to play the game fine with just the one card in the second slot. It seems to be the psu. I wish I had another one just to test before I pull the trigger on a new one.
