You need to now how many amps it can put out. That is a LOT of HDDs to power up. The case i bought for my server came with a 350 watt and it couldn't handle a board (25 watts TOTAL including RAM+CPU) and 8 hard drives on power up. Had to get a 450 watt. Now I am consolidating all my stuff into one PC. My now upgraded server with a 4th Gen i5 4570 can't do 4k encoding or well can't keep up. Tested on my AMD FX 8320 and had no issue so moving everything into my HAF-X Case. I had a 600 watt PSU but with a 250 watt GPU + 125 Watt CPU and other thing + what will now be a dozen hard drives, 600 watts wasn't going to cut it. I just bought a HXi1200i for 161 new out the door plus a 20 dollar mail in rebate on newegg. It is overkill yes but plan...
