The big thing I see is "Six powerful +12V rails with high maximum loads offer great compatibility with heavy-duty graphics cards". If you go EVGA 1600 you get a single rail.
I could be nut's but I think that part might cause some problems. And I could be wrong, but all mine have been single rail.
If you already own one you can use it and it will work, I have one myself I ran one from, just be careful how you separate the rails... I went one rail per board, and the 4th rail I used a splitter on and spread across all three boards plus power and it worked fine..
If you are buying something there are much better options, I would just a server PSU myself for less than an ATX option..
