[asterisk-users] No-mobo PC for USB Drives Enclosure?

[Col Ferguson]

If I understand right, your problem is that the power supply won't turn on ?
ATX power supplies can be told to turn on by jumpering 2 pins on the
motherboard power connector. From memory its the Green wire and one of the
black wires, I usually use the next one inwards. Pinouts for the connector
can be found via Google.
If the power supply also has an external on/off switch you can jumper these
pins and use the switch to turn the power on or off.

Hope this helps,
Col
