You want every part of your computer to be in optimal condition, regardless of whether you use it for online browsing or intense gaming. In the PC operation the power supply unit (PSU) of the PC plays a main role. In this guide, I will tell you how to check PC power supply wattage.
Overall power needs of a personal computer can vary greatly. Ranges from 250 W to over 1000 W for a high-end system with several graphics cards. 300–500 W are often needed by personal computers without particularly powerful CPUs or graphics cards. Read this blog post carefully step by step;
What is PC power supply wattage?
Total power range for personal computer from 250w to 1000w. Switched-mode power supplies are used in all modern personal computers. While some power supplies automatically adjust to the main voltage, others have a manual switch for choosing the input voltage.
How to check PC power supply wattage
To check your PSU to the test:
1- Turn off your power supply.
2- Except for the 24-pin cable and the main AC cable, unplug every cable from the PSU.
3- Pins 16 and 17 on your 24-pin cable should be located.
4- Pins 16 and 17 can be located by counting from the left, with the pins facing you and the clip facing up. As you count from left to right, they will be the fourth and fifth pins, as the example photo below illustrates.
5- To fit the ends of your paper clip into pins 16 and 17, bend it.
6- Put the ends of a PSU jumper into pins 16 and 17 if you’re using one.
7- Activate the power supply unit.
8- Try to get the PSU fan to turn. If so, the PSU is operating as it should.
NOTE: A zero-RPM feature found in many Corsair PSUs causes the fan to spin for a brief period after the PSU is turned on. This suggests that the PSU is still operating as intended.
To test your PSU using a multimeter, use the chart below and carry over the steps from before:
Check supply by using a power supply tester:
A power supply tester such as the one shown above is another method of testing your PSU (others can be used, this is just the most common). Use one by doing the actions listed below:
1-Turn off your power supply.
2-If any modular cables are present, disconnect them all.
3-Connect the 8-pin (4+4) CPU cable and the 24-pin cable to the PSU and tester, respectively.
4-Turn the power switch to the “On” position after plugging in the AC power cord.
NOTE: A zero-RPM feature found in many Corsair PSUs causes the fan to spin for a brief period after the PSU is turned on. This suggests that the PSU is still operating as intended.
The PSU tester’s LCD screen ought to turn on and display numerical readouts.
