Two 750W PSUs or One 1200W+ PSU

post #1 of 15
Thread Starter 
Hai everybody,

I want to try out Tri SLI 480s for some 3D surround action and I definitely need more power. Seasonics are still on sale for the day so I wanted to see if there is any benefits/drawbacks going with 2x smaller PSUs instead of one large one.

Don't worry I have ample room in my case for 2x PSUs.

I would grab one large one. because if you fold or game you will be able to run at 80 percent and be able to run more efficiently.

Yeah, I know the popular choices.

Just seeing if there are any unforseen benefits or drawbacks except for space and making sure your not overloading one or the other. I was thinking about the X-750s as they are silent up to a point.

Three cards would would take upto 900W on full load, GTX480s are power hungry cards. Get one 1.2kW instead of 2 PSUs simply because one is better than two.
