How much power do I need?

[DimaH98]

Hello im new to this but what I wanted to ask is this I currently have a AMD Radeon HD 7990 and my power supply is 1000WATTS for AZZA.

My Question is how much power do I need if I put another 7990 into my system?

Thanks

A quick google search, About 1200W

 

So, 1200W PSU for DUAL 7990's in CF, Leaves some head room for overclocking
