Can I use this card as a PhysX dedicated GPU with this Power Supply and specs?

Polistiren · May 15, 2015

Hi, I have the following configuration:

Motherboard - ASRock 970 Extreme3 R2.0
CPU - AMD FX-8320 3.5GHz box
GPU - GIGABYTE GeForce GTX 980 WindForce 3X 4GB DDR5 256-bit
Ram - 2X Crucial Ballistix Sport 8GB DDR3 1600MHz CL9 Dual Channel Kit (8 chips at 4gb)
Power Supply - CX750M ATX 750 Watt 80 PLUS
An Asus DVD Writer and a case fan (they also consume power)

I happen to have a GIGABYTE GV-N630-2GI REV1.0 lying around. What I want to know is whether or not can I use it as a Physx dedicated GPU, given my current power supply. What I've seen online is rather all over the place, either I need 500W for the 980 or it needs around 350W, etc.

Thanks in advance.

It says the card supports PhysX. You should be ok, slap it in there.

Yes I know, but it's the power consumption that worries me.

with a 750W PSU? I mean, you can use two 980's on a 750W. It's pushing it a bit but still. You should be fine as far as I can tell.

The only issue is whether the GT 630 would even be beneficial to your system. It may be so slow that when called on, it would be slower than just using the 980 for PhysX and rendering.

Thanks for the notice. I'll try it with some benchmarks and see how it turns out.
