dell H275P-00 power supply

The Dell H275P‑00 is a 275‑Watt ATX power supply designed for OptiPlex GX620/740 and similar low‑profile desktop systems. Common failure modes for this model include capacitor degradation leading to voltage ripple, fan motor burnout causing overheating, and internal fuse blowouts that cut all output rails. First‑check steps: verify the 12 V, 5 V, and 3.3 V rail voltages with a multimeter while the unit is powered on; inspect the PSU for bulging or leaking electrolytic capacitors and listen for fan noise; review any POST error codes or BIOS messages that indicate power supply issues.[oss-gpt-20b]
