Astec RS-PSU-450-4835-AC-1 84627-02A Power Supply

The Astec RS‑PSU‑450‑4835‑AC‑1 (part 84627‑02A) is a 440 W power supply unit used in Dell EqualLogic PS5500/PS6500 storage arrays and similar Astec industrial systems. Common failure modes include degraded output voltage regulation, fan or capacitor failures, and internal PCB burn marks due to over‑voltage or thermal stress. First‑check diagnostics: verify incoming AC voltage and continuity of the 12 V/5 V/3.3 V rails with a multimeter; inspect for blown capacitors, loose connections, or overheating components on the board; review any system error logs for power‑related fault codes before proceeding to component replacement.[oss-gpt-20b]
