im looking to crossfire a 4870 and 4850 and i found this psu, is it powerful enough and is the company a good company. budget is strict, the 4870 cost too much but im going for it anyway so i had to find a moderately cheap but powerful psu. please state your ideas/opinions and thanks.

Looks OK, but I think others might find this more attractive;

Oh and check on the ATI site to be sure your MB can support CrossfireX!

Do you mean you're going to crossfire either two 4850s or 4870s?
Not a 4850 with a 4870.

Btw, you'll need 8 pin PCI-e connectors for the 4870, which the PSU doesn't have. You'll need to get adapters or something.

The 2nd one only has a single 12v rail?

I get the Corsair. It's a little more expensive than the PC Power & Cooling, but if you read the reviews on the PC P&C, alot of buyers are getting dead units.

A single 12V rail is the best way to go. And as other's pointed out, crossfire 2 of the same card...don't crossfire a 4850 and a 4870.

ati.com only shows certified amd cpu mobo's but my asus p5q pro has 2x pci-e 2.0 slots that will run crossfire at 8x/8x.
