PSU for 2x HD4870 in crossfire

[stevozilik]

Hi there,

I'm building a gaming system with 2x HD4870 crossfire + E8400 + 2x 500Gbb HDD + X48.... I wanted to get Antec TruePower Quattro 850W but it got £15 more expensive so I'd like to consider other options.

Can you list good PSU for reasonable price and quality, that would handle my system ? thanks a lot!

I got OCZ 600W GameXStream that can take 2.

Mainly anything above 600W can take dual...but need a good make, and 12V rail.

Corsair make some of the best PSUs

It's good to hear that I don't need that powerfull PSU.

any other opinions?

That will handle your system fine. Its the same as Kxk's except 100 watts more.

that's no going to handle my system at all. I need 4 x 6-pin PCI-E to handle two HD4870 . :/

750 watts, strong 12v rail, and 4 6+2 pci-e pins.

excellent PSU, and only 100 bucks after mail in rebate.

You dont need 4 X 6 pin ....why does everyone think this... just use adapters for the other 2 6 pins they work fine.

The CORSAIR CMPSU-750TX 750W is an excellent power supply. I build pc's for other people. For the past several years I have been using Corsair exclusively. The psu's are very stable and reliable.

You also might want to look at PC Power & Cooling, Seasonic, and Thermaltake psu's.

drobb2626 is correct. It is possible to use an adapter cable in place of the 6 pin, 2x3, PCIe cable. The adapter cables are available from many on line vendors.

There have been posts made by other people indicating a top quality 600 to 650 watt psu can power two 4870 video cards in Crossfire mode without any problem.
