WMtec H250AD-00 250W Server Power Supply

This 250 watt power supply is built for OptiPlex 390 790 990 3010 7010 9010 desktop systems. It replaces a failed or ageing unit with a direct-fit component that matches the original form factor. The unit accepts 100-240V input at 4.4A across 50-60Hz mains. It is suited for IT technicians maintaining fleets of these specific workstations.

Replaces Dell part numbers 7GC81 07GC81 CN-07GC81

The supply matches model numbers H250AD-00 and D250A005L used in the listed OptiPlex desktops. Swapping the old unit restores reliable power delivery without adapter cables or chassis modifications. The upgrade is worth it when the original supply shows voltage instability, fan noise or complete failure. It is not for builders who need higher wattage for discrete graphics cards or additional drive bays.

Sustained 250 watt output at 100-240V input

Under continuous load the unit delivers its rated 250 watts within the specified 100-240V 4.4A 50-60Hz input range. Internal protection circuits maintain stable rails during extended workstation use. Thermal design matches the original Dell specification for the OptiPlex DT chassis airflow. It is not for servers requiring redundant hot-swap power modules or 24/7 datacentre duty cycles.
