I also have a need for multicomputer (motherboard only) ATX power supplies. Chances are we aren't the only ones, so perhaps it wouldn't hurt to suggest such a product to a high quality power supply manufacturer?
My requirements don't necessitate the motherboard being able to turn off it's power.
Within the next 6 months I expect to need:
20-60 units : At up to $30 / computer
When I have the budget approved for them I'm thinking of contacting PC Power and Cooling to see if they're interested. Their Turbo-Cool 425 ATX/ATX12V in 12-31 units is on sale for $125.74 each right now, and its rated at: +5V @ 40A +12V @ 20A -5V @ .3A -12V @ 1A +3.3v @ 40A +5VSB @ 2A (With +5 and +3.3 combined < 300W)
They're very conservatively rated power supplies, and I've never had one fail, (even in the most brutal environment I know of on computers schools.)
The only power output limitation I see for the purpose is the 5VSB power. Some NICs (particularly Gigabit, and older 100 Mbs ones,) draw more than that for the WOL. But as the computers are diskless I don't have a need for that feature.
How many quad output power supplies do you expect to need?
