1U 250W ATX Power Supply for FSP Replacement

This compact 1U ATX power supply delivers 250W of continuous power for small-form-factor systems and server chassis. It is built as a direct fit for units requiring the DPS-250AB-55C form factor. The unit targets builders and integrators who need a reliable, space-saving replacement for original FSP equipment.

80 PLUS Gold Efficiency with Zero RPM Fan Mode

The 80 PLUS Gold certification ensures high efficiency during normal operation, reducing power consumption, heat output and overall noise. A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent performance for typical desktop or edge workloads. Resonant LLC topology with DC-to-DC conversion further lowers coil whine and supports efficient sleep states.

Modern Standby Support for Fast Wake Times

Modern Standby compatibility allows the system to resume from sleep almost instantly while maintaining low power draw. This feature benefits users who rely on quick wake-up for productivity or always-on services. No additional accessories or software bundles are included with the unit.

Domande su questo articolo

How do I install the 1U 250W DPS-250AB-55C in a standard ATX chassis, and which step is most often missed?

Align the unit with the ATX mounting holes, secure all four screws, then connect the 24-pin motherboard cable and the 4-pin CPU power cable; the step most often missed is plugging in the 4-pin CPU connector.

What maintenance will the 250W DPS-250AB-55C need over its lifetime?

The Zero RPM fan stops at low load, so dust builds up unseen; clean the intake mesh and fan blades with compressed air every six to twelve months to keep airflow clear.

At what load does the 250W DPS-250AB-55C hit its first thermal limit during sustained use?

The 80 PLUS Gold rating guarantees high efficiency up to full load, but continuous operation near 250W will raise internal temperatures until the fan ramps to maximum speed.
