Professional diagnostic and board-level repair service for this Dell N275P-00 power supply.

The Dell N275P‑00 is a 275 W ATX power module used in OptiPlex GX series desktops, featuring a 24‑pin main connector and a 4‑pin auxiliary rail. Common failure points include capacitor degradation on the +12 V rails, overheating of the internal switching regulator, and failure of the AC input rectifier or smoothing capacitors due to voltage spikes. First‑check diagnostics: verify that the unit receives proper 100–240 VAC input; measure output voltages with a multimeter against ATX specifications; visually inspect for bulging electrolytics or burn marks, and test the PSU’s fan operation and thermal response under load.
