can my PSU handle it!

post #1 of 6
Thread Starter 
Ok will my PSU be able to handle my sig rig with two 9800gx2's in SLI instead of my 470 in there so replace with my 470 with the gx2's and will my rig be fine!? Cause i know there power hungry.

To be honest, I think that it wouldn't be worth trying. It would first and foremost generate significantly more heat (even more heat than two GTX 480s), but it would also mean that you could no longer benefit from DirectX 11.

So I guess I'm curious: why do you want do to this? I apologize for asking "why", but I just have a feeling that it might be something you'd regret (that is, if the 775W Toughpower XT is up to it).
It's a computer!

To answer the question , yes your psu is fine but i agree with twocables, loss of dx11 would be a step down depending on what you do with your computer. But once again , depends on what you want to do with them.
