KHACHIMO Power ONE 250W Power Supply CPA250-4530

250 W ATX power supply

This 250 W ATX unit is built for compact desktops and small-form-factor systems that need reliable, efficient power without excess capacity. It suits office workstations, media PCs and light productivity builds where a lower-wattage design keeps cabling tidy and heat output low.

Modern Standby and zero-RPM fan

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency for everyday responsiveness. The 80 PLUS Gold certification reduces power draw, noise and operating temperatures, while the zero-RPM fan mode stops the fan completely at low and medium loads for near-silent running.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power, reduces coil whine and supports more energy-efficient sleep states. This design replaces older group-regulated units that struggle with transient loads and modern sleep states; it is not suited for high-power gaming rigs or multi-GPU configurations that demand substantially more wattage.
