How do i turn on a compaq ps-7231 power supply?


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 (+5 VDC when power is Ok) 9 5VSB Purple +5 VDC Standby Voltage (max 10mA, max 2A in ATX 2.2 spec) 10 12V Yellow +12 VDC 11 12V Yellow +12 VDC 12 3.3V Orange +3.3 VDC 13 3.3V Orange +3.3 VDC. ATX V2.3 / EPS12V V2.92 both define that the PSU has to use remote sensing to compensate cable drops on the 3.3V line. Because of this there is an additional brown cable crimped together with the orange cable either to pin 13 (ATX) or pin 1 (EPS12V). 14 -12V Blue -12 VDC 15 COM Black Ground 16 /PS_ON Green Power Supply On (active low). Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF. 17 COM Black Ground 18 COM Black Ground 19 COM Black Ground 20 -5V White -5 VDC (this is optional on newer ATX-2 supplies, it is for use with older AT class expansion cards and can be omitted on newer units) 21 +5V Red +5 VDC 22 +5V Red +5 VDC 23 +5V Red +5 VDC 24 COM Black Ground /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.

I HAVE A JENNAIR JS42CSDBDA FRIDGE THAT WENT DEAD NO POWER,NO LIGHTS CHECKED OUTLET AND FOUND POWER GOING TO FRIDGE BUT NOTHING. IT ACTS AS IF IT'S NOT EVEN PLUGGED IN.


No one turned off your power switch up above the refrigerator, I trust. So, either your power supply or your main PCB is blown. Check the fuse on the main PCB (up on top of your refrigerator in the compressor area). The fuse will be right next to that round, black piezo electric speaker on the main PCB board as shown here:


52f3d145-54c2-4885-b0b7-dceebc8d9c83.jpg
If that's not it, then check to see if your power supply board is supplying power by measuring the voltage on JP11 of the Main PCB. You should see 26 vdc between pin 3 (GND) and pin 1. And, you should see 12 vdc between pin 3 (GND) and pin 2.

If you don't get those voltages, then you might have a bad Power Supply Board. It looks like this:

73a3b2de-febc-4413-9ad4-529414e074c1.jpg
Also of note, your 120vac going into the Main PCB board comes in on JP8, pin 1 (WHT) and pin 5 (RED).

I don't know if you will be able to see the larger image of the schematic, or if Fixya will just give you a thumbnail, but I'll try to post it here, anyway:

Well, good luck and let me know if you need any more assistance.

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.
If this helps you resolve your problem, please
consider giving me a rating of 4.It will help me as well. Thank you.

The DB15 VGA (Video Graphics Array) connector contains however 15 pins in three rows of 5 pins each. These five pins carry the color and synchronisation signals, also a digital I2C interface for two-way communication between the video controller and monitor. The common 15-pin VGA connector found on most video cards, computer monitors, high definition televisions which support VGA connections. The following schematic diagram and table shows respectively connector and pin assignment of DB15 VGA.

Power supply


ATX Version 1.2 - 20 wire motherboard connector Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8 Pin 9 Pin 10 3.3V 3.3V Gnd 5V Gnd 5V Gnd P_OK 5VSB 12V Oran Oran Blk Red Blk Red Blk Gray Purp Yell Oran Blue Blk Green Blk Blk Blk White Red Red 3.3V -12V Gnd P_ON Gnd Gnd Gnd -5V 5V 5V Pin 11 Pin 12 Pin 13 Pin 14 Pin 15 Pin 16 Pin 17 Pin 18 Pin 19 Pin 20 The color scheme used for the voltages in the 20 pin connector holds for the other ATX standard power supply connectors. However, brand name manufacturers often build proprietary power supplies or make up their own color coding, so I wouldn't throw out a power supply that supplies 5V where you think it should supply 3.3V. It's more likely a proprietary design than a failure.
