![]() ![]() also, I sacrificed the floppy drive power connector (smaller white plastic connector with the same four wires as the other standard molex connectors that you power up your hard drives or optical drives with) to hook up the fan connector: tape off the extra black wire and red wire and connect one of the black wires to the black wire of the fan connector and the yellow wire to the yellow wire of the fan connector.will have an extra black wire, just have eight pairs of black wires) connect the remaining 7 black power supply wires (ground on pin #3, #5, #7, #15, #17, #18, and #19) to the remaining 8 black wires (ground on pin #3, #5, #7, #11, #14, #16, #17, #18, and #19) on the harness connector (and if using a 24-pin power supply, i.e.tape off the power supply blue wire ( would-be optional -5V on pin #20) i.e.connect the power source blue (-12V on pin #14) wire to the harness connector blue wire (-12V on pin #13).connect the power source yellow wire (+12V on pin #10) to the harness connector yellow (+12V on pin #10) wire.connect the power source green wire (power on pin #16) to the harness connector green (power on pin #15).will have an extra orange wire, just have three pairs of orange wires) connect the 2 power source orange wires (+3.3V pin #1 and #2) to the 3 orange wires (pin #1, #2, and #8) on the harness connector (and if using a 24-pin power supply, i.e.tape off the power source grey ( would-be power good on pin #8) i.e.connect the power source orange and small gauge brown (+3.3V and smaller gauge 3.3V sense on pin #13) to the orange and brown (pin #1) on the harness connector.Then attach the various wires by twisting them together and then tapping them up with some electrical tape. I also found the above table and image online please reference just in case your colors don't match (as wire color means nothing, just helpful).Ĭlip off the 22 pin connector (you know, give yourself a couple inches to work with) from your dead power supply and clip off the 20 pin connector from the good power supply and unsheathe a centimeter from all the ends of the wires (using a wire stripper tool). ![]() the power plug lined up with the back of the G4 opening for the power plug). Also note, make sure the power source fits (i.e. no need to jump voltage from 5V to 14V or even 28V). (20-pin omits the last 4: 11, 12, 23 and 24) Colorįinding a 22 pin power supply was hard for me so, I just re-used a power source from an old Windows machine (a 20 pin, but you could easily use a 24 pin as well) AND, note that the standby pin #22 states 28 Volts but I got mine to work with the standard 5V (i.e. How to use a standard 24-pin or 20-pin ATX power supply for a 22 pin power supply (e.g. ![]()
