Hello, I have a built a watercooled Maximus VI Formula based machine that refuses to power up.
mother board has all 3 ATX connectors attached. If I disconnect the 24pin supply and short the restart pin I can get the power supply to provide power to HDD, Fans & Pump etc.. but when connected to the board the on board start button or the chassis button connected to the system panel connector does nothing.
Does the Maximus VI need a CPU Fan connected in order for power to be provided to the board? I have a stock fan but not to hand
Rather frustrated that I didn't check the board before building the system and fixing the pipework in place.
Many thanks for any guidance.
