Help with extracting power from a PS with no MoBo

[Diabolik]

I am replacing my SCSI raid array with an ATA raid (less noise from drives and fans...). I need to move the data. However, I have a feeling that my 340w PS will not be able to handle 6xSCSI + 6xIDE at the same time. So I want to use a second PS for the ATA drives. However, an ATX PS does not turn on if no motherboard is connected.

I know there is a way to bridge two connectors in order to cheat. The question is how? Thanks!

Yes, if you use a jumper or short wire to connect the power on wire (green) with the ground next to it (black) your PSU should power on.

My dual-PSU PC is so powerfull that the neighbourhood dims when I turn it on
