Hp 6000/8000 ATX adapter

Some HP business class desktops use a proprietary Power Supply with (2) 6 pin connectors
This PCB allows you to cut off the connectors from your current power supply and use a
standard 24-pin ATX power supply
you still need a small 5v to 12v boost converter which can be found on ebay

Note: I had to use a 3-wire fan instead of a 4-wire fan to get rid of the [NO Power Supply Fan] warnings

6 Month update:
Board works flawlessly, I had the boards made by JLCPCB in black matte
looks a lot better than the one I home etched but same functionality albeit slightly smaller
I salvaged my connectors from an old motherboard and the 5V convertor came from ebay
This is the same design as I got but any 5v -> 12v output boost convertor should work
There isn't a very high current draw.. its only for standby power
