Will this PSU be enough and work alright?

Looking to get that PSU and put it into this case:

http://www.newegg.com/Product/Product.aspx?Item=N82E16811119245

Gonna add the optional 4 120mm fans.

This is my setup:

Kandalf LCS with ASRock P67 Extreme6
i5 2500K @ 4.4ghz/1.260v - 720w Enermax PSU
2 x 250gb WD 1TB Seagate 150gb Raptor 1TB
Crucial RealSSD C300 128gb for Windows 7
8gb of G.Skill Ripsaw X Series DDR3 1600
eVGA GTX 570
X-Fi Fatality Sound Card and Logitech Z5500
24" Acer P234W and a 20.1" Viewsonic VX2025WM

I'm asking if the PSU will be enough because I plan to SLi the 570 in the future. Also, all the extra fans and whatnot. Just want to make sure I have all the power I need and room to spare!

More about will work alright
  1. Nice case man ;)

    Yeah that PSU is fine for the case, fans and SLI, plus a little extra.

    Your build is looking really nice :)
  2. For a system using two GeForce GTX 570 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 800 Watt or greater power supply that has a combined +12 Volt continuous current rating of 56 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

    The Corsair Professional Series Gold AX850 (CMPSU-850AX), with its +12 Volt continuous current rating of 70 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is sufficient for your build.
  3. Feel pretty good right now! The 720 I use works great with the single setup! Just wasn't sure how close I am to pushing the limits of it now due to the 5 harddrives and overclocking everything. I figured 850 would be enough but just wanted to be sure! I have no idea how much juice harddrives suck up.

    You're saying it's sufficient, but am I better off getting a 1000w? I see Corsair makes a 1050w but it's not Gold.
  4. Total Power Supply Wattage is NOT a crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.
  5. You're good man. The 850 is fine.

    If you want options though, I have both of these:

    The 1000 is rated a bit better but both are good.

    Edit:

    See the rebates ;)

    This is going to come off as me questioning your knowledge but I promise it's not! I just feel comfortable with Corsair or Enermax so I prefer to stick with them.

    I was looking at this one. Because I imagine that "Platinum Certified" is the best certification they offer? And it's 83amps @ 12v. It's a little expensive but I paid a lot for my Enermax Liberty and it's lasted 5 years while working perfect the entire time.

    80 PLUS certification is based on the power supply's AC power to DC power energy conversion efficiency:

    80 PLUS
    80 PLUS Bronze
    80 PLUS Silver
    80 PLUS Gold
    80 PLUS Platinum
    80 PLUS Titanium
