Need PSU size advice on new build.

post #1 of 12
Thread Starter 
Building a new computer with the following specs:

Intel i7 920
Asus MB
6 GB DDR3
(2) Nvidia GTX260's in SLI
(2) 1TB HD's
DVD Burner

What size of PSU would be enough? I don't want to spend a fortune on something that is oversized that I don't really need.

The Corsair 750w should do just fine.

Just go for one of those 1000W. It'll cover your next upgrade as well as this one.

Waste of money IMO...

Go with the 750TX.

My recommendation: http://www.newegg.com/Product/Produc...007&Tpk=es-800. It's better than the Corsair.
