Subj : Connectors POWER SUPPLY CONNECTORS - Typical Power Supply has 6 Connectors: 2 ea. - 6 pin for Motherboard Power and 4 ea. - 4 pin for Disk Drive Power. Motherboard Power Connectors P8 P9 Pin Signal Pin Signal ----------------------------- --------------------------- 1 - Power Good 1 - GND 2 - +5v (or N.C.) 2 - GND 3 - +12v 3 - -5v 4 - -12v 4 - +5v 5 - GND 5 - +5v 6 - GND 6 - +5v Disk Drive Power Connectors (4 - 4 pin) Pin Signal ----------------------------- 1 - +12v 2 - GND 3 - GND 4 - +5v MOTHERBOARD CONNECTORS - Motherboards have various combinations of connectors depending on design type and built-in facilities. These will be found in a typical clone.
