275W replacement for OptiPlex Mini Tower

This 275W server power supply is built as a direct replacement for Dell OptiPlex 3010, 7010 and 9010 Mini Tower desktops. It matches the original part numbers CF5W6, VGDDM, 61J2N, D3PMV and 56DXG as well as model numbers H275AM-00, B275AM-00 and L275AM-00. The unit suits IT teams and home users restoring or maintaining these specific workstations.

Standard ATX connectors and 100-240V input

The supply uses the standard ATX connector layout required by the OptiPlex Mini Tower chassis, so installation follows the normal motherboard and drive power routing. A wide-range 100-240V input at 50-60Hz handles global mains voltages without a voltage selector switch. The new condition means all capacitors and solder joints are fresh, reducing the risk of early failure after fitment.

Replaces aged or failed OEM units

This unit replaces the original 275W power supply when it no longer holds voltage under load or has developed coil whine and capacitor ageing. The jump is worth it when the workstation shows random shutdowns, POST failures or drive spin-up issues traced to the power rail. It is not for systems needing higher wattage for discrete graphics upgrades or for small-form-factor OptiPlex models that use a different PSU form factor.

Questions about this item

What input voltage range and frequency does the 275W unit accept?

The supply takes 100-240V AC at 50-60Hz, so it works on mains worldwide without a voltage switch.

Which Dell OptiPlex Mini Tower chassis does this PSU fit?

It is built for the OptiPlex 3010, 7010 and 9010 Mini Tower cases and matches the CF5W6, VGDDM, 61J2N, D3PMV and 56DXG part numbers.

How do I install the PSU and what step is often missed?

Remove the side panel, unscrew the old unit, slide this H275AM-00, B275AM-00 or L275AM-00 model in, secure the screws, then reconnect the 24-pin motherboard and CPU power cables — forgetting the CPU connector is the common mistake.
