I have just installed a Gigabyte UD7 motherboard into my Cosmos S and I'm not able to get the power switch to work. The power switch lead is a 2 pin female and the mother board header for the lead is a 3 pin male. The manual explains that the left pin is + and the right pin is -. There is no mention of the centre pin. I have tried the power lead on both middle left and middle right and have not managed to get the case to start from the touch sensitive button. Is there a 2 to 3 converter out there or do I simply cut the power lead socket in half and insert each wire separately? Any ideas?
