I am moving some drives into my gaming rig and want to be able to support atleast 6 HD's total. My specs for my gaming rig are in my sig. Will my TX650 be up to this or should I jump on the cheap Antec 850 Quatro deal?
HDs generally use about 5W under load, 10W at most. Your current setup probably uses around 400W under load tops, so you still have plenty of headroom even after adding the drives.
