250W Gold ATX power supply for Dell DT chassis

This 250 watt unit carries 80 PLUS Gold certification and active power-factor correction across a 100 to 240 volt input range. It fits the Dell 390, 790, 990, 3010, 7010 and 9010 desktop towers. The non-modular cable set provides one 20+4 pin motherboard connector, one 4 pin CPU connector and three SATA power leads. No PCIe graphics connectors are included.

Replaces OEM 250W PSUs such as L250PS-00.

Match the original when the output voltage, current and connector shape on the adapter body are the same or higher. The jump is worth it if the existing supply has failed, shows voltage drift or lacks Gold efficiency. Spare part numbers 07GC81, 0K2H58, 0DY72N, 0HY6D2, 0CYY97, 04M and 8GF cross-reference to this model.

Verify chassis clearance

The unit measures 17.5 by 8.5 by 6.5 centimetres and uses a fixed cable harness. Confirm the case can accommodate these dimensions and that the 4 pin CPU lead reaches the motherboard socket. Systems requiring a dedicated graphics power connector or more than three SATA devices cannot use this supply.

Questions about this item

Will the 17.5 cm × 8.5 cm × 6.5 cm unit fit my Dell OptiPlex 390, 790 or 990 DT chassis?

The supply matches part numbers 07GC81, 0K2H58, 0DY72N, 0HY6D2, 0CYY97, 04M and 8GF and is listed for Dell 390, 790, 990, 3010, 7010 and 9010 DT models.

Which cables must I connect during installation, and what is the common mistake?

Plug the 20+4 pin motherboard connector, the long 4-pin CPU connector and up to three SATA drives; the frequent error is leaving the 4-pin CPU cable unplugged because the board still powers on without it.

What upkeep does the non-modular 250 W Gold unit need over time?

Vacuum the intake grille periodically and listen for bearing noise; the internal fan is the only moving part and cannot be user-swapped without opening the sealed PSU.
