Having own power supply for CPU and VIDEO Card

post #1 of 7
Thread Starter 
I saw at Best Buy a power supply that you add on and sits in one of your empty bays on your tower. It is an extra 430 watt supply, but you hook it up to only your CPU and Video Card. Is this that beneficial. I already have 700 watt supply and only run SLI with two cards. Will it help the performance of my CPU and Video to have its own power supply.

If you're running on that 700w right now, then you don't need another unit. It apparently can power your system just fine.

I wouldn't use two, because it's hard to fit into a case, and can affect airflow.

you are far from needing any more power and would gain nothing by using that

But you could replace the lacking psu for a more powerful one instead of adding a second psu and having two psu's and creating a veritable cluster f of wires
