Hey guys, I'm planning to get another HD 7950 card, and I want to ask for some help here.
Here is some my components:
Mobo: http://www.gigabyte.lt/products/product-page.aspx?pid=4434#ov
CPU: FX 8350
PSU:http://www.gigabyte.lt/products/product-page.aspx?pid=3606#kf
VGA: http://www.gigabyte.lt/products/product-page.aspx?pid=4121#ov
RAM: Kingston Beast 1600 9 CL running at 1.8V

The question: Is another same GPU will be ok with this components, or I have to change PSU? I have checked, and the connection slots will be enough, the thing is about power?

Anyway I will wait for any other ideas, how to make this thing work :)

Thanks :)

According this: http://www.thermaltake.outervision.com/ my config with second VGA would pick about 500W power, my block is 620 W. Its not good??

I have read a lot of articles, where people says that in crossfire you need at least 750w PSU, but still dont understand WHY the numbers so different.
 


You will definitely need another power supply to run the 7950 in crossfire without any issues. You always want to shoot higher on the power supply and your 620W PSU is equivalent to a 500W high-end brand power supply.

I recommend the Corsair brand and they are currently on sale at Newegg.
