dual psu.....is it possible?

post #1 of 22
Thread Starter 
i have a tesla c1060(wich i will be using for physx) and i bought two gtx295 on ebay now i have a coolermaster 1200w psu fitted and a 750w psu laying around.
right so this idea popped into my mind "what if i would use two psu's ?",i wanna use one for the two gtx295 and another one for tesla c1060 and the rest of the computer,basically dedicate the 1200w psu to the gtx295's,now my problem is how am i gonna make both of them to start when i turn my pc on?

A quality 1200w PSU will hand your needs easily.

You don't want to use multiple PSUs unless you really understand PSUs.

Negligible load. To put it simply, your computer would run fine on just one 750W unit.

Yes, although what you have will be more than adequate.
