Delta Electronics DPS-450FB b Rev 00 6500668 power supply

The Delta DPS‑450FB B Rev 00 6500668 is a 450 W redundant server power supply designed for Dell PowerEdge SC/960/980 models and supports hot‑swap operation. Common failure modes include capacitor degradation or shorted electrolytics, fan motor burnout, or DC output voltage drift due to aging rectifier diodes; the internal switching regulator can also fail if the input AC is unstable. First‑check diagnostics: verify 120 VAC (or specified input) and measure the PSU’s output rails with a multimeter; inspect for visual signs of overheating, bulging caps, or fan failure; and review any diagnostic LEDs or error codes that may indicate a failed internal component.[oss-gpt-20b]
