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!
