Will a 700w PSU handle 6850 Xfire

post #1 of 15
Thread Starter 
As the title says.

I have a 700w PSU and I want to add another Gigabyte 6850 and Crossfire it, here are my specs for my AMD rig:

AMD Phenom II X4 965 at 3.4Ghz
Gigabyte GA-890FXA-UD5
Gigabyte 1GB ATI Radeon 6850
AeroCool E80-700 watt power supply
4GB G.Skill NQ 1600Mhz DDR3 RAM
Western Digital 500GB SATA hard drive
LG BluRay/DVD combo drive
Coolermaster HAF 922
Coolermaster V8 CPU Cooler

My PSU has two 6x PCI-E connectors, will it be enough?

Well, I had GTX 470 SLI running on an Antec 750w so I would say any quality 700w should handle 6850 crossfire without breaking a sweat. As for Aerocool, I know nothing about them so I can't comment on that particular unit. That being said, I'm sure someone here who knows a lot more about PSUs will help you out!

Yeah

if you run on stock maybe but i just don't trust aerocool

many ppl after me will post that 700w is fine and blah blah blah but i like to be on the safe side and use a psu that will definitely run my machine+

Two 12v rails @ 30 amps each, so yeah, it's more than enough.
