Internal 255W PSU with 8-pin and 4-pin

This unit is a 255 watt internal power supply designed for specific small-form-factor desktops and servers. It provides one 8-pin graphics connector and one 4-pin CPU connector through a non-modular cable set. Active PFC operates across a 100-264V input range. The unit carries no 80 PLUS rating and is sold new.

Fits 3020 7020 9020 SFF and T1700

It matches the listed Dell OptiPlex and Precision workstations using part numbers such as L255AS-00, H255ES-00 and YH9D7. Builders needing higher wattage, modular cables, an 80 PLUS badge, or different connector counts must choose another model. The fixed harness cannot be reduced or rerouted for tight custom loops.

Single 8-pin GPU and 4-pin CPU limit

The decisive specification is the fixed pair of one 8-pin and one 4-pin output. Any graphics card requiring two 8-pin plugs or a 12VHPWR connector cannot be powered. Any motherboard demanding an 8-pin EPS connector will not fit. Verify both requirements before ordering.

Questions about this item

What does the 255W rating mean for my Dell OptiPlex 3020, 7020, 9020 SFF or T1700?

It is the maximum continuous power the unit can deliver to the motherboard, CPU and graphics card through its single 8-pin and single 4-pin connectors in those small-form-factor desktops.

What interface does the power supply use and what does it limit?

It uses a fixed 8-pin PCIe connector for graphics and a 4-pin ATX12V connector for the CPU, so it cannot support components that need dual 8-pin or 6+2-pin power.

What physical space and mounting does the unit need to fit?

It is built for the proprietary small-form-factor chassis of the OptiPlex 3020, 7020, 9020 SFF and Precision T1700, matching their original screw holes and bracket.
