I am going to build a i5 budget pc.
I dont have much to spend on a GPU, so I was thinking of getting the HD 5770 now and another later on to CF when the games I want to play like Starcraft 2( early next year) and Diablo 3( not sure when) come out so I can play in high settings.
The monitor I will be using is 1900x1080.
My question is due to these gpu's low power consumption, is 750W psu necessary like for other graphic cards, or can i get away with 650W.
MY build will look like
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333
GIGABYTE GA-P55-UD4P LGA 1156
SAMSUNG CD/DVD Burner Black SATA
Seagate 7200 rpm 500gb HD(this I had alrdy otherwise I would go for spinpoint F3)
The older Earthwatts from Antec were actually made by Seasonic themselves (same company that makes that Corsair we listed above) but this model is made by Delta Electronics and there quality isn't quite as good. Not bad by any means just not on the same level.
I noted you plan to Crossifre the HD 5770's too. This PSU will allow that with the lesser manufacturer quality I'd be leery to use it. And you'd be limited to using GPU's with a single 6 pin PCIe each and nothing bigger such as the HD 5850's.
