I found a power supply that’s supposed to be a replacement HP power supply at my local computer store and it had that exact same 4-pin “video power connector”…and it was actually marked as such. It was a Athena PSU 200 watt MP3ATX20
The tech there said this connector is rarely used. But, as you said, it was used in some HP Pavilions that had the Ensoniq sound card.
I can definitely put this question to rest.
Does anyone know what the -5volt connector is used for in an HP Pavilion XL866 AMD Athlon? Not many PSU’s have this particular voltage (-5V @0.3A Max is on my dead PSU which is a “LiteOn PS-6161-2H1”).
I need a replacement for the LiteOn PSU…the XL866 is a micro ATX…so it has to be like 3.25" H x 4" D x 5.75" W in order to fit in the case.
The dead LiteOn PSU has 9 connectors: 1 each 20-pin mobo connector; 5 each molex (could get by with 4); 1 each 4-pin Floppy Drive connector; 1 each 3-pin PS (I suppose PS means the power supply) fan; and 1 each 4-pin “video power connector”.
By the way, is a 4-pin ATX12V connector for Pentium processors? This connector is square with 4-pins and I was told it’s for P4’s…just trying to confirm…my computer is a AMD Athlon 1.1GHz cpu.
