Good tip, thanks punish3r, I'll check it out.
I went over the Digi-Key options, and I'm not happy with a single one of them.:shrug:
Three PSUs will be mounted in the 5 1/4 bay areas, as soon as I figure out how to trim 1/8" from the sides...
I'll also be wiring in a lit AC switch to each PSU
along with status LEDs for "Stand-by" and "Power_ OK".
I'm also wiring in a pump relay, with a power outlet, not to cut the pump cord.
