## Long description

The Dell 305W PFC JH994 internal replacement unit is a compact power supply designed to provide up to 305 watts of continuous output for compatible Dell systems. This internal module integrates active power factor correction (PFC) to improve electrical efficiency and reduce harmonic distortion. Intended as a direct replacement for failed or missing original units, the supply delivers stable voltages and reliable current to motherboard, storage devices and peripheral components when installed in supported server or workstation chassis.
Advantages
The unit combines a 305 W power rating with active PFC to maintain efficient AC-to-DC conversion and reduce reactive current draw from the mains. Its form factor and connector layout match common internal Dell designs, enabling straightforward swap-in replacement without extensive modifications. Built for sustained operation under typical server or workstation loads, the supply helps maintain system stability and decreases electrical noise that can affect sensitive components.
Suitable for
Repairing a compatible Dell server or workstation that requires a 305 W internal power supply
Replacing a degraded or non-functional internal PSU in supported chassis
Keeping as a spare part for maintenance and rapid field swaps
Small office or laboratory builds where a compact internal PSU with active PFC is required
