Dell PS-5161-7DS Power Supply Repair Service

Professional diagnostic and board-level repair service for this Dell PS-5161-7DS Power Supply.

PS‑5161‑7DS is a 160 W switching power supply for the Dell OptiPlex GX280SFF desktop. Common failure modes in this unit include capacitor degradation on the 3.3 V/5 V/12 V rails, fan burnout or stalling, and transformer winding insulation breakdown leading to shorted output lines. Begin troubleshooting by verifying that the AC input voltage is within the specified 100‑240 V range and that the PSU’s internal fan is spinning; then measure each DC rail with a multimeter for correct output voltages and inspect the electrolytic capacitors for bulging or leakage. If any rail deviates from spec, replace the affected capacitor or transformer section before reassembling. Post Comment
