Dell DPS-650BBA Power Supply

The Dell DPS‑650BBA is a 675 W redundant, hot‑swap power supply designed for PowerEdge 1800 servers, delivering 12 VDC at up to 55 A from a 100–240 VAC input. Common failure points in this class include degraded capacitors on the high‑current rail, failing MOSFETs or bridge rectifiers, and fan or thermal sensor faults that trigger protection shutdowns. Initial checks should verify input voltage stability, confirm output current capability with a multimeter or clamp meter, inspect for bulging electrolytics or overheating components, and review any system logs or error codes indicating power‑related issues.[oss-gpt-20b]
