You may have a faulty power supply, if so you need to replace the faulty power supply.
Do not try to repair this power supply because mains equipment are dangerous if you do not know what you are doing.

The only place I can think you will find an actual schematic for the PSU is from the manufacturer.

ATX-300-12Z was hit with a power surge (thought we had a surge protector). Green light on power supply blinking at 2X/second. No power at USB devices (or anywhere else.) PC was on when surge hit.


There were 2 Switching power supply circuit inside the ATX PSU. There's a Standy PWM circuit whichSupply +5V to the PWM IC of the Main PWM. Stand by pwm still working or insufficient voltage, lower than +5V. This is the reason you still have Green light. Check or replaced small filter capacitor around 100 MFD 16V, open resistor or shorted diode that was nearest of the PWM IC..
Watch out for charge voltage on big capacitors.

I want to convert this power supply for use with a battery charger for model aircraft. I need to know the color codes for the wires and also the pinout and which wire is the power on.


Pin Name Color Description
1 3.3V Orange +3.3 VDC
2 3.3V Orange +3.3 VDC
3 COM Black Ground
4 5V Red +5 VDC
5 COM Black Ground
6 5V Red +5 VDC
7 COM Black Ground
8 PWR_OK Gray Power Ok (is a status signal generated by the power supply to notify the computer that the DC operating voltages are within the ranges required for proper computer operation)
9 5VSB Purple +5 VDC Standby Voltage (max 10mA)
10 12V Yellow +12 VDC
11 3.3V Orange +3.3 VDC
12 -12V Blue -12 VDC
13 COM Black Ground
14 /PS_ON Green Power Supply On (active low). Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF.
15 COM Black Ground
16 COM Black Ground
17 COM Black Ground
18 -5V White -5 VDC
19 5V Red +5 VDC
20 5V Red +5 VDC

/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.
