Dell DPS-650-BB-A Power Supply

Dell DPS‑650BB‑A is a 675 W redundant hot‑swap power supply used in PowerEdge 1800 servers. Common failures on this model include internal fuse blowouts, capacitor degradation, and fan motor burnout; symptoms are sudden shutdowns, error codes indicating “PSU failure,” or audible clicking from the PSU housing. First‑check steps: verify that both input mains voltages (120 V/240 V) are present and within tolerance, then confirm the PSU’s LED status indicator shows green or amber rather than red; next inspect for visible signs of overheating or burnt components on the PCB, and finally read any POST error codes from the server BIOS to isolate a single‑side failure.[oss-gpt-20b]
