Compact 1U 250W ATX Replacement

This 250W ATX power supply is built in a 1U form factor and serves as a direct replacement for the DPS-250AB-44 A and DPS-250AB-44 K units. It targets system integrators and IT professionals who need a compact, brand-new unit for rackmount servers or slim desktop chassis.

Sustained load efficiency and acoustics

The 80 PLUS Gold certified platform uses Resonant LLC topology with DC-to-DC conversion to maintain high efficiency and clean power delivery during continuous operation. Zero RPM fan mode keeps the unit silent at low and medium loads, while Modern Standby compatibility ensures fast wake times and efficient sleep states.

250W total output limit

The single deciding specification is the 250W maximum power rating, which restricts this unit to low-power CPUs and configurations without discrete graphics cards. Builders requiring higher wattage for multi-drive arrays or dedicated GPUs must select a higher-capacity power supply.
