Can my PSU handle all of this?

post #1 of 10
Thread Starter 
Hey, My PSU is running my sigrig just fine
It's a Corsair TX750W
My question is, what happens if I add another 9800GT or a GTX 260 as a PhysX card? will it handle the load? I'm going to use PCI-e to Molex converters if that's going to work.

What do you say?

I'd say a provisional yes, but it will be pretty tight. So long as all the 3rd card does is PhysX, it will work.
If you try and fold on all 3, expect OPP shutdowns.

More than enough. Your two GTX 275 are probably pulling ~350W or under while gaming. A 9800GT would add no more than 100W to that.

I dont *really* plan on using a 3rd card for so long. You see, we're gonna have some lan party at my friend's house pretty soon, and we're gonna try all kind of stuff on our computers, switch graphics card, combinations and stuff. anyway I'm not gonna use the 3rd card for more than 30mins or so, and it's just gonna be for benchmarks and tests

If Phaedrus says, Phaedrus is right.

I tried running through it based on your sig rig, but it came out with an insane kilowatt, so I probably screwed something up >.< At any rate, there's some stuff I wouldn't know about your system from the sig rig anyway. Hope it helps!

With my rig (SLI and everything complete) I got 661W in this calculator. those tend to exaggerate and be fairly inaccurate so I'd say my system doesn't use over 550W.

You will be fine.
