Can my PSU support these two cards (physx)

#1vinnied717Posted 8/4/2013 8:49:12 AM
I just received my MSI gtx760 OC a few weeks ago and it is supplanting my old EVGA SSC GTX460.

I think I'm getting tired of seeing it collect dust on my desk so I was curious if my PSU could support both cards w/ the 460 being used for Physx. I already know that there is VERY little benefit to doing so I figure I could use it in this manner until I find someone that may want to buy it.

The PSU is an Antec TP-650. It sounds like a silly question because this was a very good PSU when I bought it two years ago but you never know...

If you really want a dedicated physx card you should sell that GTX 460 and buy a GTX 650 with the money as it uses a lot less power and I mean a lot less power according to graphs I'm looking at in comparison to that 460.

It would be fine, with room to spare. You are right that the TP-650 is a good unit, it still is even though it's no longer really sold.

Nah, if it was enough, he'd be cutting it real close.

What are you talking about... the 760 is a 150-175W card, the 460 is about the same, but in PhysX mode you'll never hit full load, so it's going to be far less than the sum of both cards at full load.

That PSU is plenty. You could probably SLI 780s on it.

I agree, the 460 and the 760 should be a piece of cake on 650W. Especially if you're running a power-efficient CPU.

Lol at anyone thinking it's a possible issue running with that PSU.

It says 54 amps max on +12v rail:

Those cards couldn't possibly use more than 330 watts. Whole system couldn't possibly be more than 500 watts.

Saying he can't use those cards on that PSU is like saying I can't use 780 on my 50 amps +12v rail PSU
