255 W replacement for Optiplex desktops

This new YINGHUA unit supplies 255 W to Dell Optiplex 3020 7020 9020 and T7100 systems. It replaces L255AS-00 D255AS-00 H255AS-00 H255ES-01 F255ES-00 and HU255AS-00 models. The metal enclosure fits the original mounting points for a direct swap. Builders restoring those towers can install it without adapter cables.

Steady output under continuous demand

The supply delivers its rated 255 W across the rails required by the listed Optiplex platforms. High-efficiency components keep voltages stable during extended workloads such as file serving or background rendering. Thermal design dissipates heat through the chassis without throttling. Sustained operation stays within specification when the host system draws near maximum load.

Metal chassis with standard ATX connectors

A 24 cm metal housing matches the factory form factor and screws into the existing bracket. Main power and peripheral leads follow the original pin-out so drives and motherboard seat firmly. No extra brackets or cable extensions are needed for the supported models. The unit suits repair jobs where the original supply has failed or shows voltage drift.

Questions about this item

How loud does the 255 W unit run when the Optiplex 7020 is under full load all day?

The supply uses a standard internal fan that spins up only when the chassis temperature rises, so noise stays low during typical office workloads and increases only under sustained heavy draw.

Which power cables must already be present in the Optiplex 9020 for this PSU to connect?

The replacement plugs directly into the existing 24-pin main connector and 4-pin CPU connector on the motherboard; no extra cables or adapters are required.

Will the 24 cm long housing fit alongside the original drive cage in a T7100 tower?

Yes, the 24 cm length matches the factory unit, so it occupies the same bay and leaves the drive cage and expansion cards untouched.
