280W L280P-01 Dell Optiplex Replacement

This Vszerda power adapter is a new 280 watt unit built to replace the original supply in Dell Optiplex GX520, GX620, 740, 745, 755, 210L, 320 and 330 desktops as well as Dimension C521 and 3100 systems. It accepts 100-120V or 200-240V input at 50-60Hz and delivers up to 280W maximum output. The package includes the power supply unit only.

Who This Suits and Who Should Look Elsewhere

This unit fits owners of the listed Dell Optiplex and Dimension models who need a direct replacement for part numbers such as L280P-00, L280P-01, H280P-00, H280P-01, D280P-00, MH596, MH595, RT490 or NH429. Builders who need higher wattage for modern graphics cards, additional PCIe power connectors, or a standard ATX form factor for non-Dell cases should look elsewhere.

280W Maximum Output Decides Compatibility

The single specification that decides fit is the 280W maximum output combined with the proprietary connector layout of one 24-pin motherboard plug, two SATA power plugs, one 4-pin Molex, one floppy power plug and one 4-pin ATX power plug. If your Dell chassis and motherboard require exactly this wiring and wattage, the adapter will work; if the system demands more power or different connectors, it will not.

Questions about this item

How can I verify the 280W L280P-01 is working after installation?

Power on the Dell Optiplex; the system should POST and remain stable under load, confirming the 24-pin motherboard, 4-pin ATX, two SATA, one Molex and one floppy connectors are all delivering power correctly.

What comes in the box and what must I source separately?

The package includes one 280W power supply unit only; you will need to reuse the existing IEC C13 mains cable and any additional drive cables your configuration requires.

Which compatible part number should I match when choosing this unit?

Match the original Dell part number — MH596, MH595, RT490, NH429, P9550, U9087, X9072, NC912 or JK930 — or the model numbers L280P-00, L280P-01, H280P-00, H280P-01, D280P-00, B235PD-00, D235PD-00, H235PD-01, D233N, M618F or M619F.
