Will a Corsair HX850 work with SLI 570's

Alright guys sorry if this kind of redundant but I want to make sure for my specific build.

Right now I have a CORSAIR Professional Series HX850 in my system with a single EVGA SuperClocked 012-P3-1573-AR GeForce GTX 570 HD. I wanted to get a second one and wanted to make sure that the PSU would be enough to handle that load. The specs I have currently are :

EVGA SuperClocked 012-P3-1573-AR GeForce GTX 570 HD
ASUS 24X DVD Burner
Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB Cache
G.SKILL Ripjaws Series 16GB
Crucial M4 CT064M4SSD2 2.5" 64GB
Intel Core i7-2600K Sandy Bridge 3.4GHz
CORSAIR Professional Series HX850 (CMPSU-850HX) 850W
ASUS P8Z68-V PRO LGA 1155 Intel Z68

So basically, 1 SSD, 1 Hard Drive, 1 Disc drive, and the single 570.

The links from newegg for the video card and PSU are

So what do you guys think. Will that PSU be enough to run two of those 570s, any feedback will help.

  1. Your psu is fine. Thats a quality unit. Enjoy
  2. That is more than enough.

    NZXT & Corsair PSU's FTW.
  3. Quality PSU, although I would suggest getting a 2500k to save ~$100 if you are not using hyper threading and are only gaming ect...

    2500k, you wont regret it.

    And yes it should be fine.

    Good luck!
  4. Alright cool, Ill order the new video card today,

    @appleshaq I bought all of the things listed and I had heard that same thing from other people too lol.

    For a system running with two GeForce GTX 570 graphics cards in 2-way SLI mode, NVIDA specifies that the power supply unit should have a minimum of 800 Watts or greater with a combined +12 Volt continuous current rating of 56 Amps or greater and with at least four 6-pin PCI-Express Supplementary Power Connectors.

    Your Corsair Professional Series HX850 (CMPSU-850HX), with its +12 Volt continuous current rating of 70 Amps, is more than capable with plenty in reserve for any overclocking of the CPU and GPUs that you may want to attempt.
