I have a question on the best power supply for a JBOD cage holding a dozen hard drives. It seems that many power supplies dedicate, at most, one rail for hard drives. I don't want to go down the spinup/MAID/power up on standby road, since about every raid controller out there is different, as are most hard drives and how they react to those commands.
My question is this - if I want a power supply for a JBOD cage, what's my best bet? It seems as though most PS's dedicate much of their output to the PCIe connectors. I have no use for that, obviously. Is there a way one can recover at least one of the rails, such as tapping the 5V and 12V on the 20/24 pin ATX connector and making a custom 4-pin Molex harness off of that?
Can one tap the 12V rails on the PCIe connectors and splice in the 5V supply from the ATX connector to recover some more 12V current capacity? I assume that there is a single 5V rail that feeds everything coming out of the PS since I've never run across a PS with 2X/3X/4X 5V rails. Any thoughts are appreciated. Thank you.
