How to limit power supply draw from GPU?

[rihsc102]

I have recently upgraded to a GTX 970 and my 470w power supply can't handle it. I think it's only a few watts under as sometimes I can game for hours and other times the PC cuts out and reboots every 10 minutes.

I have ordered an EVGA P2 850w as I plan to upgrade the other components soon, but is there anything I can do until it arrives? I tried using MSI afterburner to limit power draw but that strangely has no effect, and I tried turning down in game graphics settings but again, it didnt work.

Any ideas?

Either underclock/undervolt the GPU (personally I wouldn't recommend that) or what's better, reduce the maximum FPS for the games it happens. For example if a game runs at 150fps just limit it to 60fps, that would reduce the power draw by a large margin and still the game will be playable.

Nope, not much you can do here, you probably have a low quality power supply. I would just leave the system alone till the new PSU gets there, running it the way you are just puts all your components at risk. An unstable power supply can kill everything else in the computer.

Put your old video card back in? You could probably do System Restore to put the old drivers back if it hasn't been very long. Did you kake a backup or restore point when you put the new card in? It would be a way to keep running until the new PSU arrives.
