Hi,

I am going to upgrade my current rig to have my 7850 crossfired

Here is my current rig:

Processor: FX 6300
Motherboard: Asus Maximus VI Gene
RAM: G.SKILL DDR3 8GB SR 2133 (4GBx2)
HDD: Seagate SSHD 1TB
GPU: HD 7850
Power Supply: 550W

Which wattage power supply will I need to upgrade to in order to run crossfired 7850s?

Thanks.
