Compatible Dell OptiPlex MT power supply

This 240 W switching power supply replaces units in Dell OptiPlex 3040, 5040 and 7040 micro-tower systems. It accepts 100-240 V input at 50-60 Hz and carries part numbers 0M1C3, W72XN, DHVJN, H62JR and 0TRD3. The unit ships as one of the compatible model variants D240EM-00, AC240EM-00, L240AM-00, H240EM-00 or B240EM-00.

Fits OptiPlex 3040 5040 7040 MT only

Buyers repairing or upgrading those specific micro-tower models will find the correct connector layout and 240 W rating. Systems requiring higher wattage, a different form factor or proprietary pin-outs used in small-form-factor or all-in-one chassis cannot use this unit. Shops needing redundant or hot-swap server supplies should look elsewhere.

Steady 12 V rails under continuous load

The supply delivers +12VA at 16.5 A, +12VB at 16 A and +12V standby at 2.5 A. Combined 12 V current stays within the 240 W limit during sustained operation, avoiding the voltage droop seen in short-burst ratings. Thermal protection engages if internal temperatures exceed safe thresholds during prolonged use.
