Report ID: PSU-DIAG-2024-01 Date: [Current Date] Subject: A systematic approach to verifying the operational health and output stability of a computer Power Supply Unit. 1. Executive Summary The Power Supply Unit (PSU) is the foundational component of any computing system. It converts AC mains electricity into regulated DC voltages required by the motherboard, storage devices, and GPUs. A failing PSU is notoriously difficult to diagnose because its symptoms (random reboots, hard drive failure, video corruption, “no POST”) often mimic motherboard or RAM issues. This report details the five primary methods of checking a PSU, ranging from non-invasive software checks to physical hardware validation using multimeters and dedicated testers.
