Before delving into hardware, a safe and methodical approach begins with software and observation. Users should first eliminate simple software causes by checking the Windows Event Viewer for critical Kernel-Power errors (Event ID 41), which indicate the system rebooted without cleanly shutting down. While this confirms a power anomaly, it does not condemn the PSU alone; a failing motherboard or overclocking instability can mimic the same error. The true diagnostic value here is corroboration: if these errors coincide with periods of high power draw (gaming, rendering), the PSU becomes the prime suspect.

The most definitive test for the home user is the "paperclip test" or the use of a dedicated PSU tester. To perform the paperclip test, the PSU must be completely disconnected from the motherboard, drives, and peripherals. After shorting the green "Power On" (PS_ON) wire to any adjacent black (COM) ground wire on the 24-pin motherboard connector using a bent paperclip, the user plugs in the PSU and flips its switch. A functional unit will cause its internal fan to spin. However, this test is a binary check—it only confirms the PSU is not dead. It cannot measure voltage stability, ripple, or wattage output. A PSU that passes the paperclip test can still fail under load. check power supply pc

Moving from software to hardware requires caution, as a PSU contains capacitors that can hold lethal charges. The initial physical check is non-invasive. With the PC unplugged, open the case and inspect the PSU through its ventilation grille. Look for bulging capacitors, a smell of burnt electronics, or visible dust bunnies that could cause overheating. If the unit is physically compromised, stop immediately and replace it.
