265W Server Power Supply for OptiPlex

This 265-watt power supply replaces the original unit in Dell OptiPlex 790, 990, 390, T1600, 7010, 3010 and 9010 mini-tower systems. It matches part numbers GVY79, 053N4, 9D9T1, YC7TR and D3D1C as well as model codes H265AM-00, L265AM-00, AC265AM-00, F265EM-00 and L265EM-00. The unit accepts 100-240 volt AC input at 50-60 hertz.

Suitable for direct replacement.

It suits IT staff or owners restoring or repairing the listed OptiPlex mini-towers with a new, compatible power supply. Builders needing more than 265 watts for upgraded graphics cards or additional drives should look at a higher-capacity unit. Small-form-factor or micro-tower chassis that require a different mechanical design are also not served by this adapter.

265 watt maximum output decides fit

The single specification that determines compatibility is the 265-watt maximum power rating. Verify that the system’s original power supply is rated at 265 watts and uses the same part or model numbers before ordering.

Questions about this item

How can I verify the 265W power supply is working correctly after installing it in my OptiPlex 7010 MT?

The system should power on reliably, show no POST errors, and remain stable under load; the fan should spin and the unit must accept 100-240V~ 5.0A 50-60Hz input without shutting down.

What comes in the box with the WMtec 265W adapter and what extra parts are needed for an OptiPlex 990 MT?

The package contains the 265W power supply unit only; you must reuse the existing IEC power cord and mounting screws from the OptiPlex 990 MT chassis.

Which model number — H265AM-00, L265AM-00, AC265AM-00, F265EM-00 or L265EM-00 — matches the GVY79 part for my OptiPlex 3010 MT?

All five model numbers (H265AM-00, L265AM-00, AC265AM-00, F265EM-00, L265EM-00) correspond to the same GVY79 / 053N4 / 9D9T1 / YC7TR / D3D1C part and fit the OptiPlex 3010 MT.
