8800 Gt

see thats what i thought as well because my other power supply had 19 amps on each rails as well. but it turned out i needed 25 amps on each rail or something. plus it didn't help that my power supply was rated at what it was suppose to be. so that is why i bought a the corsair 750 wat one. 60 amps on each rail i do believe.

If I'm not mistaken (and I may well be), the rails are separate and it would only draw from one with a single power connector. That PSU has two native PCIe connectors. I would try an adapter that will let you hook two Molex connectors into a single PCIe connector and see what that does. The specs show it has six Molex connectors, if there are three connectors on two native cables try one from each cable in this adapter. If it does split the amperage that will provide power from both.

I've heard multi-rail PSUs derided for this very reason.

Edit: I used to run an 8800GT off of two 400-watt PSUs this way, one Molex from each separate PSU, and it ran fine. They only had one rail each at 16A.

So you would suggest something like this so that It can draw power from both rails?

So for future reference this PSU would work becuase it's single rail at 30 amps.

Yes, on both counts. Personally, because of stuff like this, I won't buy a multi-rail PSU. Also, PC Power & Cooling and Corsair don't make multi-rail PSUs (except for the 1kV Corsair), and they're the only manufacturers I'll buy for systems I really care about...

actually biggoofy i tried that with my power supply to. running off of the molexs and it didn't work. the problem is you need a new power supply. not a extension. the power supply isn't rated at what its suppose to be or isnt give you enough power. so you need a new better one like that corsair one. x88x is right corsair and pc and cooling are very good manufacturers.

Rosewill is Newegg's in house brand. Not saying that its at all bad, but their PSUs aren't up to the task of ANY gaming whatsoever.

Here's a good test for PSU. If it feels quite heavy, then it is good. If a 600 watt PSU weighs less than the paperback version of Lord Of the Rings, well....I'd get a different PSU.

Having gone the route of Rosewill in the past (WoW would lock up on me way back in the day until I got a beefier PSU), I am willing to bet that this is the issue.

I've got this PSU and its 12v rail is rated @60A I'm also running 2 Radeon HD3870x2's off this puppy with no issues. both with a 6-pin and 8-pin connector

Thanks for all the replies. Looks like I learned my lesson and seems I have to do a little more research in the PS department. And now I'm investing in a new PSU. Even though this is only 400w the rail is it 30 amps, and its super cheap after rebate.

MUCH better choice! You should be rather pleased with it.

Another plus for that new PSU Corsair has earned a reputation for quality products.
