Just want to double check before ordering (PSU)

The Corsair TX 750w would be enough for a Crossfire setup with two HD 3870 X2s, right?
Single +12v rail @ 60A should be enough for two cards, correct? I can't find how many amps each card needs.

System Specs (includes future upgrades):
GA-X38-DS4
Q9450
8GB 1066 RAM
3 HDDs
2 ODs
TV Tuner
Sound Card

newegg says it has "Crossfire Support" but it is not listed as being "Crossfire Certified" by ATI. (Even though the Corsair HX 620w is "Crossfire Certified" for two HD 3870s.)

The more research I do, the more questions I have!

  1. This will take care of your dilemma:
    With no mail in rebate.

  2. I have heard the Corsair power supplies are very good, efficient and stable.

    But, personally i would go with a PC Power & Cooling Silencer 750 Quad (Crossfire Edition)

    I bought one for a friends build, and I love it. We are running a Q6600 @ 3.6Ghz (50% OC) and a 2900XT (which is a juice hog), and it is super stable!

    Maximum PC even used it in there 2007 "Dream Machine." And they have no budget for the "Dream Machine," so they could have used any powersupply they wanted!

    PS. It also will match the 3870 X2's, and costs about the same as the Corsair you mentioned (without the mail-in-rebate hassle).
  3. ahhh......Bobbknight beat me to it! (Fist shaking in the air)
  4. Well I found the Corsair for $115. Unfortunately, I do have a budget for my build, lol.

    I was actually comparing it to the PC P&C because they are pretty similar (although the PC P&C will output more than 825w at peak and I can’t confirm the same for the Corsair)

    I'll second this recommendation.
  6. Well I bought the Corsair 750w for $107.49.

    Even cheaper than the 650w I was gonna get.

    Thanks for the input though.
  7. Nice, where did you get it from?
  8. @ Buy.com it's $145 (same price as on newegg.com)

    But, if you use the following coupons...

    $30 mail in rebate from Corsair (if purchased through buy.com)

    5% off total purchase price (found on retailmenot.com)

    ...then it comes out to be $107.49 after rebates including shipping and handling.
