5. How to test whether the computer power supply is broken? How to simply test whether the power supply is good or bad?

Specific steps:

(1) First we need to find a conductor wire, which can also be a common paper clip at home, or iron wire. On the 24PIN plug of the power supply, insert both ends of the conductor into a green wire and a Any empty space for a black wire. (Be careful not to touch the exposed iron wire when plugging in the power supply)

(2) We insert the power cord into the power strip.

(3) Plug the other end of the computer's power cord into the power supply to power the power supply. Remember to turn it on if there is a switch on the power supply.

(4) At this time, pay attention to the power supply fan. If the power supply fan spins, it means the power supply is good. If the fan does not spin at this time, it means the power supply is broken.

6. How to test the quality of computer power supply?

Sometimes the computer is used well but becomes unresponsive the next time it is turned on, or it shuts down automatically after a thunderstorm and then turns it on again without response. The unresponsiveness mentioned here means that the power supply and CPU and other fans will not work. Here There may also be a problem with the power supply or the motherboard. First, simply judge the quality of the power supply and test it. Prepare a conductive wire. Connect the computer power supply to the 220 volt power supply to make it in the powered state. Hold the 24P connector (old-fashioned) on the computer power supply. The power supply is a 20P connector) Connect one end of the prepared wire to the hole corresponding to the green wire. The voltage of the computer power supply is only 5V. You can operate it with confidence. Then connect the other end of the wire to the hole corresponding to any black wire. At this time, check whether the fan on the computer power supply is rotating. If the fan on the computer power supply is rotating, By rotating it, you can basically confirm that the computer power supply is good. If the power supply fan does not rotate, it means that the computer power supply is broken.

7. How to test the quality of computer power supply?

If you want to quickly test whether there is a problem with the computer power supply and whether it is a good power supply, turn on the product directly to see if it can light up normally. If the computer cannot light up normally, check whether the data cable connection socket is open and check the power supply.

Whether there is a normal 220 volt power input and the output terminal reaches the normal voltage, all computer power supplies use DC voltage output. It is easy to detect using a multimeter. I hope my answer can help you.

8. How to test the power of computer power supply?

1 Use the power meter to test 2 The power meter can be plugged directly into the power socket, and then connect the computer to the power meter for testing. When testing, the computer needs to be fully loaded, such as running large software or games. After the measurement, you can check the data displayed by the power meter. This data is the current power consumed by the computer. 3 Alternatively, you can view your computer's power plan in the power management options, which displays the computer's estimated power consumption. However, this method is only a rough estimate, and the actual power still needs to be tested using a power meter.

9. How to test the PG signal of computer power supply?

The P.G signal is the POWERGOOD signal in the power supply, also known as the "power good" signal. In the ATX power supply, this signal is called the PW-OK signal. After the microcomputer is turned on, due to the different output voltage timing of each channel, it is easy to cause confusion to the working status of the motherboard. Therefore, a delayed P.G signal is provided to the motherboard in the power supply. This signal has been available since the birth of the IBM-PC. It is still used today. The requirements for this signal are: after the power is turned on, it is generated with a delay of 100ms to 300ms relative to the +5V voltage, and when the power is turned off, it disappears 100ms in advance. Its waveform corresponds to the time of +5V voltage. On the motherboard, this signal has a logical AND relationship with the RESET signal of the host. After powering on, when the P.G signal jumps from 0V to +5V, the microcomputer starts to start. When there is no signal from P.G, the microcomputer is equivalent to pressing the RESET button all the time. (At this time, the hard disk light and the optical drive light are always on) and cannot enter the initialization state; when turning on the machine, if the timing sequence of the P.G signal and other output voltages is confused (usually the delay time is insufficient), the machine will not start after turning on the machine, but The difference from when there is no signal is that the machine can start again when the RESET button is pressed. Pay attention to distinguish these two types of faults. If the signal is unstable and disappears after starting up, the host will restart frequently. The P.G signal is controlled by the power supply, indicating whether the power supply is ready, and the PS_ON# signal is controlled by the motherboard, indicating whether the power needs to be turned on. Both signals are connected through the 20-core motherboard power cord. The working process of turning on and off the computer is as follows: after the AC line is powered on, the power supply outputs a voltage of +5VSB to the motherboard, and a small number of lines on the motherboard start to work. And wait for the power-on operation, this is called standby state; when the host switch is pressed, the motherboard turns the PS_ON# signal to low level, and after the power supply is connected to low level, it starts to start and generate all output voltages. Within 0.1~0.5 seconds after normal establishment, the power supply will change the P.G signal to high level and transmit it back to the motherboard, indicating that the power supply is ready, and then the motherboard will start to start and run. During normal shutdown, after completing all shutdown operations, the mainboard returns the PS_ON# signal to high level, the power supply turns off all output voltages and P.G signals, leaving only the +5VSB output, and the entire host returns to standby state. When shutting down abnormally, the motherboard cannot give a shutdown signal. At this time, the power supply will detect the AC power outage and change the P.G signal to low level to notify the motherboard. The motherboard will immediately perform an emergency reset of the hardware to protect the hardware from damage. . In this case, after the power supply notifies the motherboard of a power outage, it must maintain the normal output voltage for at least one thousandth of a second for the motherboard to reset, otherwise some hardware may be damaged.

10. Simple test method for Lenovo computer power supply?

Get a power supply somewhere else and try it~ Or take the power supply somewhere else and try it~ Or turn off the external power supply, remove the computer power supply, find a paper clip (thin copper wire or iron wire is fine), and short-circuit the power supply The green and black (either black is acceptable) pins in the plug connected to the motherboard must not be connected incorrectly, otherwise you will be responsible for the consequences.

Find a socket with a switch and connect the power cord to the computer power supply. If the main power supply at home does not have trip protection, it is recommended to disconnect some household appliances first.

Connect the power supply with the switch of the socket. If the power fan rotates, it means the power supply is basically normal; if there is an abnormal sound, it means the computer power supply may be damaged, please cut off the power supply immediately.

If the power supply is basically normal, with power on, adjust the multimeter to the DC 20V range and measure according to the nominal voltage of the motherboard power socket in your motherboard manual.

It is best to use a digital meter to judge the quality of the computer power supply by observing the voltage and fluctuations. Also pay attention to personal safety when operating.
