Because of the Great deals last week I pulled the trigger and bought another 8800gtx. Problem is nothing seems better. In the middle of a game, system will just turn off. No BSOD just OFF:eek:. No benchmarks are any better. Could this be a power supply issue?
 
If the PSU just shuts off, and it's not a thermal issue, then it could be overloaded.

What's odd though is that the PCIe connectors are on their own rails. Each pair have a rail capable of 18A. 18A * 12V = 216W. That should be more than enough as it already exceeds the mechanical specifications of the PCIe connectors!

Take a look at the PCIe connectors. Two of the connectors should have yellow wires with green stripes and two should have blue stripes. Do you have them hooked up as both green striped wires to one card, blue stripe to another or are they mixed up?
 
Jonny Thnx for responding. I don't think I'm smart enough to answer your question:eek: But What I can tell you is that the power supply only has two pci-e plugs so I had to use 4 4pin into the pci-e adapters that came with the cards. Hope this tells you something LOL
 
You're not smart enough to tell me the color of a wire? LOL! :)

Ok... I thought that PSU had four PCIe. If there's only two and you're using splitters, that explains a lot. You're putting too much load on +12V2.

Are the splitter-to-6-pin PCIe adapters both on one card or do you have one splitter and one native 6-pin on each card?
 
It doesn't matter if it has four +12V rails if it only has two PCIe connectors. Because the PCIe connectors are each on their own rail, the CPU is on a third rail, and everything else is on the fourth rail. Everything else being: hard drives, optical drives, fans, etc. and now the power connectors you're adapting from Molexes to feed those graphics cards.

Quite frankly, although "700W" should be enough for your build, that particular PSU simply was not meant to run a pair of 8800 GTX cards.
 
Can you recommend a power supply so I don't have this problem in the near future. I would be greatful for your advise:D PS. If not a specific brand then how many watts should I be looking at. Thnx again.
 
Make sure it has four PCIe connectors. Then it's made to run SLI with four PCIe connectors in the first place. ;)

If you want to make it really easy on yourself, just go to SLI Zone and see what's certified for GTX SLI.
 
DAHHH:eek: Thnx 4 all u r help man:cool:. Think I'll read somemore of u r reviews b 4 I go 2 SLI zone:D U have been a big help mad props 2 U
 
I bought a second GTX too and the OCZ 700 is just not cutting it anymore - the specs at OCZ do say it should have 4 pci connectors but I bought my PSU about a year ago when I first built my rig and it only comes with 2. I am using the included adapters from eVGA to turn my 4 pin adapters into PCI adapters. It runs, but if I do anything too strenuous - say 3dMark06 4th test or 1920x1200 with options on high for Crysis it powers down. I sent OCZ a tech support question, especially as I bought the PSU when I did because it was SLI ready and I new I was going to get a second card down the line when they became cheap enough. I borrowed a friends BFG 800 to test if it was the PSU and it sure enough is - with that in there I experienced no issues at all.
