Does a PSU supply power when it is plugged in? I just bought a new Fortron PSU for my project 40Ghz Xeon. Anyway, that is off-topic.
So I have it plugged in to AC power, but not hooked up to a computer... and no fan noise.
I hooked it up to two hard drives connected to another computer with a separate PSU... and nothing. (The other computer boots fine, but did not recognize my two hard drives.)
Are PSUs more sophisticated than I had guessed? Do you need the PSU to be hooked to the motherboard with the big-ass connectors to get it to work at all?
In case you are wondering WTF I am trying to do... here goes.
I have a 400gb HD and I need to copy the info to another 400gb HD. But I am short on computers that have native SATA power supply connectors. And I had this brand new Fortron $90 PSU just sitting there waiting for Project 40ghz Xeon. The Fortron has two SATA power connectors.
Thanks for your help!
