The HP 750W, 1200W and 1500W are Common Slot PSUs, which are in no way the same as this 800/1000W (DPS800GBA I believe). A generic board made for Common Slot PSUs won't work for the DPS800, and a DPS800 board won't work for a Common Slot PSU, but my board was made specifically to work with both.
Thanks.
I never sent you that board back to get fixed, I just never got around to it and may not, remember we talked about it and you asked me to send it...I may buy another one from some one who still sells some and he has some in stock still, to find out and i kind of had that feeling if your board didn't work it was either the board or PSU, making sure .
I had two of your boards at one time but got care less with one but the one i still have and use, I didn't mess up or i wouldn't have told you about it , just never sent it back ...
