Um, unfortUNATELY THAT SETUP WILL NOT work.
The sr-2 requires xeon server chips not i7 consumer products. And it needs 2 of them
I also believe it requires server ram so make sure you get them.
You really should look for a better psu. The sr-2 uses 2 8 pins, and the psu you choose is low on the Amps.
This Antec is cheaper and alot more Amps.. Newegg.com - Antec High Current Gamer Series HCG-750 750W ATX12V v2.3 / EPS12V v2.91 SLI Certified CrossFire Certified 80 PLUS BRONZE Certified Active PFC Power Supply
Now folks... Please please look at the parts before giving "suggestions"... As TJ found out it is a dual socketed server board that allows for overclocking..
The 990x is expensive, but if building a power cruncher, video editing, simulations etc.. The 990x again totally destroys a 2600. Each chip has its good points and uses.
My.... What are your itended use of this thing? A regular server board is 1/3rd the price, and a couple of cHT Quad xeons are about the same as the 990x or its xeon counter part.. Plus you need 2.
You need to rebuild your build as it will not work... literally.
It will destroy a 2600k.. because it's designed for a whole different use.
