r9 290 crossfire

Hey I was thinking about upgrading to a crossfire setup with my r9 290
and was wondering if my 850W gold powersupply would be sufficiant.
Thanks in advance.

Hi Neagal,
Can you provide us what is the make and model of the power supply you have? I need to look up into the the rails and also the amperes.
Thank you.

Hi,
You are fine with this power supply. It has a single rail design with 70.8A which is enough for a CrossFire configuration with the 290 cards.

OUTPUT

Rail +3.3V +5V +12V +5Vsb -12V
Max output 24A 24A 70.8A 3.0A 0.5A

Total 850W @ +50C
