I have a test unit set up with 5 Antminer S5's , The Bladecenter appears to be handling it OK. but I think this has got to be close to the max for it. I am wondering if it would be safer to just run 4 per Bladecenter. Can't complain about how loud the S5's are since you can not hear them over the Bladecenter's fans.

Awesome! I've got 4 S5's arriving tomorrow and already have the PSU here. How did you "rig" yours up until the board is available? Do you have pictures? I thought the S5 only pulls around 560W x 5 = 2800W. The BladeCenter H PSU's are 94% efficient 3180 * .94 = 2989W that your S5's are pulling or 597W each. So, it's all pretty close I guess.
