  • Designed for PowerEdge R430 and R330 server integration

Dell PowerEdge R430 and R330 Compatibility

This power supply is built for Dell PowerEdge R430 and R330 servers. It uses a standard ATX form factor to fit the chassis. The unit targets IT teams maintaining these specific rack platforms. Buyers needing a supply for other server models or desktop builds should look elsewhere.

80 PLUS Gold Efficiency Under Load

The 80 PLUS Gold rating means high efficiency is maintained during sustained operation. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight when the server runs continuously. Zero RPM fan mode stays inactive under heavy load, so active cooling engages automatically. Coil whine is reduced even during prolonged high-current delivery.

ATX Interface and Modern Standby Limits

The ATX connector set limits use to systems with matching pinouts and power-good signalling. Modern Standby support enables fast wake from low-power states on compatible motherboards. Servers lacking the required firmware hooks will not benefit from the quick-resume feature. The design does not support redundant hot-swap configurations.

Questions about this item

How does the 80 PLUS Gold rating affect heat and noise when the PSU runs all day?

The 80 PLUS Gold certification means high efficiency, which lowers power draw and reduces heat output. Combined with Zero RPM Fan Mode, the fan stays off at low and medium loads for near-silent operation.

What Dell server models must I already own for this 4HPKX unit to fit and work?

This power supply is designed for the Dell PowerEdge R430 and R330. It uses the correct form factor and connectors for those specific chassis.

Will the resonant LLC topology and DC-to-DC conversion cause issues with older components I keep in the R330?

The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine. It supports modern, energy-efficient sleep states compatible with the server platform.
