How to Test the Power Supply Unit (PSU) in Your PC
Testing your computer''s power supply unit is fairly simple. You can test the PSU with a basic jumper test, multimeter, or power supply tester. This will help you rule out power delivery issues as the source of your problem.
Important Facts About Power Supply Voltage . The power supply can only use what''s being provided by the power source. So, if the outlet is transferring 220v of power but the PSU is set to 110v, it will think the voltage is lower than it actually is, which can cause damage to the computer''s components.

The PSU is one of the most important foundations of the system. 08-08-2012 01:26 PM. I dont know how but my PSU is not dropping in Voltages like it was fresh out of the box. Now 12v are only dropping to 11.9v under 100% load. 5v are staying above 5v and the 3.3v are only dropping to 3.28v.
The Power Supply Unit. The computer''s power supply unit (PSU) converts the domestic alternating current (ac) mains supply voltage (220-240 volts in Europe) into various regulated, low voltage direct current (dc) outputs required by the components that make up the computer system. The PSU usually takes the form of a metal box 150mm wide x …
Ensure the voltage range selected on the DMM is suitable for the expected voltage output of your PSU. If uncertain, start with a higher range and adjust accordingly. Attach the Probe Leads: Connect the black probe lead to the COM (common) port on your DMM and the red probe lead to the VΩmA (voltage) port.
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies .
PSU: How to test a PSU (Power Supply Unit) – Corsair
Plug in the 24-pin cable along with the 8-pin (4+4) CPU cable into the tester and to the PSU. Plug in the AC power cord and flip the power switch to the On position. NOTE: Many Corsair PSUs have a zero-RPM feature that results in the fan only spinning for a moment after the PSU is powered on. This still indicates that the PSU is functioning ...
Power supply unit (PSU) calculators work by analyzing the components in a computer system and determining the power requirements of those components. They use information such as the wattage of the CPU, GPU, and other components to estimate the total power consumption of the system.
