250W ATX Power Supply

The KHACHIMO DPS-250AB-66A is a 250 watt ATX power supply built for small-form-factor desktops and office workstations. It carries 80 PLUS Gold certification and Modern Standby compatibility for efficient low-power states. The unit delivers clean, consistent power through a resonant LLC topology with DC-to-DC conversion.

Replacing Lower-Efficiency Units

This supply upgrades older ATX units that lack 80 PLUS Gold efficiency or Modern Standby support. The jump is worthwhile when a system needs faster wake-from-sleep times, reduced coil whine, and lower overall power draw at typical office loads. It also removes the need for a fan spinning at idle.

Build Integration

The ATX form factor fits standard chassis cutouts while the zero RPM fan mode keeps acoustics near silent at low and medium loads. Resonant LLC topology with DC-to-DC conversion frees up thermal headroom by reducing waste heat. Modern Standby compatibility enables deeper sleep states without extra configuration.

Questions about this item

What case clearance is needed for a standard ATX power supply?

The unit follows the ATX form factor, so it fits any chassis with a standard ATX PSU bay and four rear mounting screws.

How do I enable the Zero RPM fan mode?

The fan stops automatically at low and medium loads; no BIOS or software setting is required.

When should I plan to replace the internal cooling fan?

The fan is rated for continuous operation; replace it only if bearing noise appears or the fan stops spinning under load.
