The crossfire (5750 and 7850) crossfire will require 600 watts (about 55 amp on 12+ rails). The 6950 is about 49% better than 5750.

Eremi :

Those combinations will not work in crossfire. They have to be the same generation and same core chip inside of the gpu's.

Ah, so what about HD 5750 and HD 5950?

Eremi :

Nope they have a different GPU. Here is a chart to go by: http://www.techpowerup.com/forums/attachments/amd_crossfirex_chart_1618w-jpg.56836/
