250W ATX power supply for compact builds

The KHACHIMO DPS-250AB-55B delivers 250W of continuous power in a 1U form factor suited to small chassis and low-profile systems. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for rapid wake-from-sleep performance. Resonant LLC topology with DC-to-DC conversion supplies clean, stable voltage rails.

Check physical fit and power budget before ordering

Verify that your case accepts a 1U power supply and that the ATX connector layout matches your motherboard. Ensure the 250W rating covers the combined draw of your CPU, graphics card, drives and peripherals under full load. Confirm the unit’s fixed cable set reaches all required headers in your build.

Sustained-load behaviour with thermal control

Under continuous demand the resonant LLC design maintains tight voltage regulation while the Zero RPM fan mode keeps the cooling fan off at low and medium loads for silent running. When temperatures rise the fan engages to sustain output without throttling, and the Gold-rated efficiency limits waste heat during extended operation.

Questions about this item

Does the KHACHIMO DPS-250AB-55B include power cables or must they be purchased separately?

The power supply unit itself is supplied; any required ATX cables for your specific build must be sourced separately.

Should I choose this 250W model or a higher-wattage unit for my system?

Select the 250W unit if your total component draw stays below that limit; otherwise a higher-capacity supply is needed.

What does the 80 PLUS Gold rating mean for daily power draw and heat?

It certifies at least 80% efficiency at typical loads, reducing wasted electricity and keeping temperatures lower.
