Okay I've searched up and down the web and can't find anything about this connector.
First off this is a 300-watt Compaq PSU from a Presario 7000 Desktop.
This Compaq computer won't power up. When I installed a standard ATX-12 PSU, the green light on the mobo came on but because most ATX-12 PSU's don't come with this very proprietary connector the computer failed to boot up. The CPU fan didn't even twitch. But the mobo green light AND the PWR LED on the front of the case lit up. Neither lights came on with the original Compaq PSU.
This connector is white and labeled "P8" and is a 6-conductor white plug. The overall size is similar to the power connectors you plug into your hard drive and other IDE devices. It looks like an oversized floppy drive connector. The wiring colors are: Red, Orange, Orange, Black, Black, Black.
I've traced the wires and here's where they go to the PSU's circuit board:
Red - connects to the same red lead on the IDE power connectors
Orange - connects to the same orange leads on the main power (mobo) connector
Black - connects to what looks like the PSU's chassis ground.
It looks pretty straight forward and I could probably modify a standard ATX-12 PSU to a Compaq PSU by snipping off this 6-conductor plug and splicing into a generic PSU's standard wiring.
But before I attempt this, is there anyone out there that knows the pin configuration on a standard/generic ATX-12 PSU and a Compaq PSU?
Thanks.
