Dell DPS-650BB power supply

Dell DPS‑650BB is a 675 W redundant hot‑swap power supply used in PowerEdge 1800 servers. Common failures on this model include internal fan burnout, capacitor degradation, and output voltage sag due to aging electrolytics or thermal cycling. First‑check diagnostics: verify the unit’s input voltage and polarity with a multimeter; inspect for visible signs of overheating, bulging capacitors, or fan obstruction; confirm that both redundant rails are delivering the rated 12 V/48 V outputs and check the server’s event logs for power‑related error codes.[oss-gpt-20b]
