Professional diagnostic and board-level repair service for this Shuttle PC4313502 power supply.

Shuttle PC4313502 is a 400 W industrial‑grade power supply used in compact workstation and server chassis. Common failure modes for this model include electrolytic capacitor degradation on the +12 V/5 V rails, fan motor burnout or bearing wear leading to overheating, and occasional voltage regulator IC failure that can cause output droop under load. First‑check diagnostics: verify input AC voltage and polarity; measure each regulated rail (+12 V, +5 V, +3.3 V) with a multimeter while the unit is powered on; inspect for bulging or leaking capacitors and listen for fan noise or abnormal vibrations.
