Replacement 420W ATX PSU for HP DX2300M

This Replace Power unit is a direct replacement for the original 250W supply in HP DX2300M and DX2300 series desktops. It restores reliable operation to systems suffering from a failed or ageing power module. The reduced-depth form factor matches the chassis constraints of these specific models.

Single-rail 12V output with 16A capacity

The power supply delivers its 420W rating through a single +12V rail rated at 16A, alongside +3.3V and +5V rails at 13A each. This rail configuration is the critical specification that determines whether the unit can support the installed components. Auxiliary rails provide -12V at 0.8A, -5V at 0.5A and +5VSB at 2.5A.

Fits HP DX2300 chassis with 20+4 pin main connector

The PSU connects via a standard 20+4 pin ATX main connector and a dedicated +12V plug, matching the motherboard headers in the target HP systems. It accepts 115V or 230V input at 50 or 60Hz without manual switching. Hold-up time is 17ms and rise time is under 70ms. It is not suited for builds requiring higher 12V current or standard-depth ATX dimensions.

Preguntas sobre este artículo

How much power does the 420W rating actually deliver to the components in an HP DX2300M?

The unit provides a single +12V rail at 16A, +3.3V and +5V each at 13A, -12V at 0.8A, -5V at 0.5A and +5VSB at 2.5A, matching the original 250W part's output specification.

What does the 20+4 pin connector mean for compatibility with the motherboard?

The 20+4 pin main connector fits the standard ATX motherboard socket used in the DX2300M series and the split design also works with older 20-pin boards.

Will the reduced-depth chassis fit the original mounting points in the DX2300M case?

Yes, the supply is built as a direct replacement for HP part numbers 441390-001 and 440569-001 and uses the same ATX mounting pattern.
