PSU for 2x HD4870 in crossfire

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!

  1. 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
  2. It's good to hear that I don't need that powerfull PSU.

    any other opinions?
  3. comme on, some advice! :)

    That will handle your system fine. Its the same as Kxk's except 100 watts more.
  5. 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.
  7. thank you, that looks much better!

    any more quality suitable powersupplies?
  8. You dont need 4 X 6 pin ....why does everyone think this... just use adapters for the other 2 6 pins they work fine.
  9. i have the same worries too.. will the Corsair 620W handle 2 x sapphire hd4870
  10. 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.
