Power supply startup solution hp PS-3381-1C1 PSU

Hi Guys

Ive managed to get one of these power supplies powered up and working ok.

Its rated at 32A and I've had it running at 20A without it getting warm at all

Heres the solution ,

- Simply connect the 3 pins in the photo to ground. There are 4 grounds/negs, these are the ends of both sides of the boards.

- The 12+ is the long middle section on the top

- Connect all 4 grounds together and this is your negative. (note the thick white wire wraps top to bottom at both ends

- Cover the pcb with "Magic Plastic" to prevent any shorts

And your done

Any questions give me a shout
