Check power suppy computer dead or work

A computer's power supply (PSU) is a crucial component, responsible for converting wall outlet power into the various voltages needed to run your system. When it malfunctions, it can lead to a range of frustrating issues, from random crashes and reboots to complete failure to power on.

If you're experiencing computer troubles and suspect your PSU might be the culprit, there are several ways to check and test it. Here are a few simple methods you can try:

1. Look for Warning Signs:
Before diving into technical tests, observe your computer's behavior for clues. Some common signs of a failing PSU include:
Random shutdowns or reboots: This can happen under load (gaming, video editing) or even during idle periods.
On of problem about this.
Pin connector, unplug and plug again.
If you fell, can solve a while. Check again pin main power and pin 12V/DC

Inability to power on: If your computer doesn't turn on at all, the PSU could be completely dead.

2. Basic Checks:
Before you perform any tests, ensure it's not a simple issue:
Double-check the power cable connections: Make sure both the wall outlet and the PSU plug are secure.
Test a different power outlet: Try plugging your computer into another outlet to rule out a faulty socket.
Check the power switch: Some PSUs have a physical on/off switch on the back. Ensure it's turned on.

3. The Paperclip Test (Advanced):
This method is for more experienced users and should be done with caution. You'll need a paperclip and some basic knowledge of PSU pinouts. With the PSU disconnected from everything, bend the paperclip to touch the green wire (labeled PS_ON) and a black ground wire on the 24-pin connector. If the PSU fan spins, it's likely getting power, but this doesn't guarantee proper voltage output.
This method, to make sure your power good or broken.
Specially chip, many user always plug-in electric power to power supply
That make ruin your power for long time.
