Hi I have a Gigabyte board GA-880GM-UD2H (rev. 1.3) and just bought a new power supply. I was wondering since the new power supply is missing the #20 pin -5v would this stop my motherboard from turning on? In the manual next to the ATX pins it gives (Pin 20 | -5v) does this mean pin 20 is required in order for the board to turn on?
