Service overview

Signs of a Failing PC Power Supply

The power supply unit (PSU) is one of the most commonly overlooked causes of PC problems. A failing PSU can cause symptoms including random shutdowns, instability under gaming load, PC refusing to turn on, clicking or buzzing noises from the case, or BSOD errors that seem hardware-related but change when the PSU is swapped.

PSU failures are also a safety concern - a faulty unit can deliver incorrect voltages that damage other components including the motherboard, CPU and GPU. We test the PSU under load using specialist equipment rather than just a simple paper clip test, ensuring accurate diagnosis.

See our full desktop PC repair page for all faults we cover.
