CPU: i5 3570K
GPU:Sapphire Radeon HD 7850 2GB
RAM:Mushkin Enhanced 8GB RAM
Hard Drive: 2TB WD Black

I MIGHT choose to get a second 7850, for crossfire. And, any recommended companies will be appreciated.

let's see believe a professional review site or the village idiot...not that is funny...i think I will laugh at that

Radeon HD 7850 - On your average system the card requires you to have a 500 Watt power supply unit and 650 Watt if you go with two cards in Crossfire mode.

UNLESS you get a very good 550W... 650W is a safety margin. But whatever.

I would not Xfire HD7850...

I was almost going to choose the other guy as best answer. Can you specifically name any "very good" 550W power supplies?

OK so I can not seem to find a well price very good 550W PSU anyway. BUT the above 650W is only 79$ after rebate, which is cheaper than most 550W PSUs anyway.

I run 2 hd7950s on that EXACT PSU.
