What unit is power supply?
Despite the name, Power Supply Units (PSU) do not supply systems with power – instead they convert it. Specifically, a power supply converts the alternating high voltage current (AC) into direct current (DC), and they also regulate the DC output voltage to the fine tolerances required for modern computing components.

How does a power supply unit work on a computer?
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.
How to troubleshoot the power supply unit ( PSU )?
Some power supplies are auto-switching and do not have a physical switch. For those that do, make sure the power cord is unplugged and flip the switch back and forth; again making sure it is set to the proper voltage. Plug the power cord in and test.
What should I consider when choosing a power supply?
Another factor you’ll need to consider when choosing a power supply is the different 80 Plus efficiency ratings. 80 Plus (trademarked 80 PLUS) is a voluntary certification program intended to promote efficient energy use in computer power supply units (PSUs).
What kind of power supply do I need for a GPU?
Central Processing Unit (CPU) – Be sure you know the make, model or series, and socket size. Graphics Processing Unit (GPU) – You will need to account for the actual power draw and the number of additional power pins a GPU may have. It’ll be either 6, 8, 6+6, 6+8, or 8+8-pins – and that’s per GPU.
