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

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

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!

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.

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.

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.

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
