Hi guys,
I have an HP XW4600 that I'm trying to use as the basis for a 3 GPU mining rig. I have just purchased an EVGA Supernova G3 750W PSU as the power supply.
https://www.evga.com/products/product.aspx?pn=220-G3-0750-X1The PSU plugs into the motherboard correctly, but when I press the ON button the computer powers for half a second then I get a red flashing light and a "beep, beep" noise.
After doing a bit of research it looks like the HP motherboard uses proprietary power and isn't compatible with ATX power. Has anyone successfully got an ATX power supply to work with a HP motherboard? Or have any tips on how to make them compatible?
