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.[oss-gpt-20b]
