Minimum Wattage for 2 x R9 290s in Crossfire

[futureslay]

Hi,

New here, but you guys seem to have a very helpful and responsive community, so this was my best bet!

Just picked up 2 of the Gigabyte R9 290 (Windforce) cards, for an amazing deal. I'm not sure about power supplies. My current one was bought with expansion in mind because I originally had one HD7870 GHz, with the intention to buy another further along the line. I currently have one of the new cards running fine, but wanted some advice on the other one being put in and roughly where I should be PSU-wise.

Specs:

MB: Asus M5A97
CPU: AMD FX-8320 (No OC)
Memory: 2 x G-Skill Ripjaws X 4GB 1600MHz
CPU Cooler: Cooler Master Seidon 120V (Water cooling)
Storage: Sandisk Ultra Plus 256GB SSD
WD Blue 500GB 7200RPM
Video: 2 x Gigabyte Windforce AMD R9 290 (4GB)
ODD: Samsung Generic CD/DVD RW drive.
Fans: 3 x 120 mm LED
2 x 80mm standard
Others: NZXT Sentry 2

Current PSU is a Corsair RM750

Cheers,
Dom

You have a nice rm750 (good efficiency and wattage) but it has heat issues so you should watch out for that (Your setup should pull less than 80% of the total wattage so you should be fine). Other than that you should be fine to put the other card in your computer.
