Special (only on the ATX conector) -Green is PSon(put a wire between green and black to turn the power on) -Gray is PWRGOOD -White is -5V(optional) -Blue is -12V -Purple is 5VSB(Always on when the PSU is plugged on) Power -Orange is 3.3V -Red is 5V -Yellow is 12V -Black is Ground (0V)

???? if it's a PC psu The connectors voltage are indicated by colors yellow is 12V red is 5V orange is 3.3V black is 0V(GND) green is PSon purple is 5Vsb blue is -12V white is -5V(optional) gray is PWRGOOD/PWROK
Black=0V(GND) Yellow=12V Red=5V Orange=3.3V Purple=5Vsb(everytime on) Gray is PWRGOOD or PWROK(pwr=power) must be at 5v White=-5V(optional) Blue=-12V Green is PWRon must be connected to a black wire to turn on the PSU

/PSON activated by pressing and releasing the power button while the power supply is in standby mode. Activating /PSON connects the power supply's /PSON input to ground, thereby switching the power supply to full-on condition. 18 AWG is recommended for all wires except pin 11, which should be 22 AWG. For 300W configurations 16 AWG is recommended. There are several ATX variants. Hope this helps. If this helps you resolve your problem, please consider giving me a rating of 4.It will help me as well. Thank you.
Hello Anvar, hi, to run the power supply on its own, you need to short the green wire with the black wire. (plug in the unit)
using a Volt meter, select a range of DC 50V. put the black probe of the voltmeter to any black wire, and the red probe to the ff:
Many power supplies have a chart on the side of the case. Here are the wire colors for an ATX type supply: RED +5, YELLOW +12, White -5, Blue -12, ORANGE +3.3, PURPLE +5VSB, GREEN Power On, BLACK -Gnd (common).
Use a paper clip to connect the GREEN wire and a BLACK wire. There should be a black one right next to the green. This is how I test PSUs before and after I repair them. Now it should be running, assuming there are no internal problems.
You can also connect the GRAY to ground with an LED. Not necessary, but I like to do it ;)
green-white for front panel Power indicator LED , Blue-white for RESET Switch , Orange-white for POWER BUTTON , Red-white for HDD LED . The berg pin header on the motherboard will have these legend printed just beside the connector or due to lack of space slightly away from it .
