At first I was pretty set on getting a Corsair 850AX but now I'm not sure if it will be enough.
This is the proposed build:

Case: Define XL Black Pearl
Drives: 1 DVD-Rom and 1 DVD+-RW
Motherboard: ASUS P8P67 Deluxe
Ram: 4x4gb Sticks of DDR3 1333 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820231312)
Processor: 2600K (Will be overclocked)
Heatsink: Hyper 212 Plus
SSD: Crucial C300 128gb
GFX Card: Undecided, looking at Radeon 5xxx series
PCI: A 4 sata card (http://www.newegg.com/Product/Product.aspx?Item=N82E16815124020)
Hard Drives: 10 Hard Drives (2TB+ Mix of 5400 and 7200 RPM)
Other: Card Reader and a KVM Switch (http://www.newegg.com/Product/Product.aspx?Item=N82E16817399056)

Please advise, I have tried multiple PSU Calculators and have gotten estimates between 792W and 1100. That's a huge difference, so would like an expert opinion.
 
Single 5xxx will not require anything greater than a 650 watt, unless you get the 5970. Even then, you probably don't need anything more than a 700-750 watt power supply. You'll probably be fine with a 550 watt and a HD5870. Are you planning to crossfire? If so, I would avoid the 58xx series, those have poor crossfire scaling (compared to the 57xx and 6xxx, and nVidia's offerings).

I am still trying to brush up on which card I should get. So far I've only narrowed it down to an ATI instead of nVidia. But unless I decide to upgrade later, I will be running one card. I thought the HD's would take a lot more power seeing as there is going to be so many.

Edit: Thanks for the opinions!
 
What kinda idiotic calculator thinks you'd need even 792w? Your system is like a 400-500w system at worst. This is exactly why I hate all psu calculators.

For the HDs, you're looking at about 15W maximum per drive, so a good ~650W PSU would be fine. This would be a good bet: http://www.newegg.com/Product/Product.aspx?Item=N82E16817207002

If you want something higher-end, look at these:

Thanks a lot, I looked at those PSU's, but it looks like I'm going to get the Corsair 850AX (same price as the 750 currently) because it has 12 sata connectors (2 DVD drives, 10 HD's) and none of the other PSU that I looked at did.
