In such instances, your second resort is the original documentation. If you built your own computer or purchased a pre-built system, the PSU’s model and wattage should be listed on the box, in the user manual, or on the purchase receipt. For those who bought a pre-assembled desktop from manufacturers like Dell, HP, or Lenovo, the original product specifications on the company’s support website, accessed via your computer’s serial number, will often list the installed PSU wattage.

Therefore, you must look at the component itself. This involves turning off and unplugging your computer, opening the side panel (usually the left side), and locating the metal box where the power cord enters the case. On one of its sides, you will find a label affixed by the manufacturer.

To find this crucial number, one cannot simply click through a menu; instead, one must look at the hardware itself, the box it came in, or use a process of deduction.
