GTX 480 SLi Power Supply Issue

post #1 of 7
Thread Starter 
Hey everyone, I have my computer over-clocked mostly and when I had a single GTX 480 It too was heavily OC'ed:1.35volts. Now with SLi 480's if I got above 1.1volts my computer during any 3D application will just shut down. When I have the system at 1.0v it runs fine during anything I throw at it.

My question is do you think my Power Supply, Antec Quattro 1000w which is about 2 years old is just getting too old to power my entire system? What you guys think? Thanks

I wouldnt have thought so i mean its 1000W, that would run on 850 wats and still have enough power , have you seen about any drivers for the card ?

I had the same problem with a Enermax 1000w PSU. I think when the cards pulled it was to much for the rail and it shut off. Mine just cut off no warning, Is that what yours is doing?

yeah, as soon as something graphic extensive comes on it would just shut down and then power on fine.

The fix was plugging in the Molex connector for extra power for the PCI-E. Thanks everyone anyways.
