Hi,

As you may have noticed on this list, power supplies are very
frequently a problem.  Just taking what you said, a ST3500630AS
7200.10 disk requires up to 2.8A peak on the +12V line, which is 28A
total for 10 disks.  The Coolermaster Real Power Pro 750 has three
separate 12V rails and each can only go up to 19A.  So that might
already be the answer, depending on how the rails match up with your
wiring.

I suggest hooking up a couple of the disks to your old power supply
and powering them up separately [1].  If you don't see any problems on
those disks then it was likely power related.
