Power Supply and crossfire 6850s

Last response: in Graphics & Displays

Hiiiiii Everrrrybody!

I am currently running an AMD Phenom II x4 with 12gb of cas9 Gskill 1600 DDR3 RAM on a Gigabyte 790XTA UD4. My PSU is an Antec Earthwatts 650. I also have 60gb kingston SSD on the way. I am wondering if anyone would recommend a PSU upgrade to crossfire two 6850s? I will probably want to overclock them, and if I run into any bottleneck issues, I will overclock the PSU. I just really don't know if the Antec EW 650 can handle it properly? Any thoughts?

Thanks!

you will be fine with the antec. the ATI 6850 is very power efficient, you won't even break 400w total system power during gaming

CPU: Intel Core i7-920 @ 3.33GHz
Motherboard: Asus Rampage II Extreme
Chipset Drivers: Intel 9.1.1.1015 (Intel)
Hard Disk: OCZ Summit (120GB)
Memory: Patriot Viper DDR3-1333 3 x 2GB (7-7-7-20)

your PSU has a 6 pin and 6+2 pin power connector. the ATI 6850 only takes one each so run each power connector to each card, a 6+2 will fit a 6 pin socket.
