Gold 80 Plus 250W ATX unit

This KHACHIMO power supply delivers 250W through a standard ATX form factor. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable output. Modern Standby compatibility enables rapid wake-from-sleep transitions and improved low-load efficiency. A zero-RPM fan mode stops the fan completely at low and medium loads for silent running.

Compact builds and quiet office PCs

The 250W limit suits small-form-factor systems, basic workstations or upgrades for older OEM chassis that require an ATX supply. Builders needing more headroom for discrete graphics cards, multiple drives or high-end CPUs should look at higher-wattage units. The fan-stop feature benefits noise-sensitive environments but cannot compensate for insufficient power capacity.

250W maximum output

This single rating determines whether the unit can support your components. Check the combined power draw of your CPU, GPU, storage and peripherals against the 250W ceiling before purchase. If the total load exceeds this figure, the supply will not be adequate regardless of its efficiency or topology.

Questions about this item

Should I choose the 250W model or one of the higher wattage versions listed?

The 250W unit suits low-power office or thin-client builds. Higher wattage models such as 350W, 520W, 550W or 750W are intended for systems with discrete graphics cards or multiple drives.

What does the 250W rating mean for my actual system build?

It is the maximum continuous DC output the supply can deliver across all rails combined. Your total component draw — CPU, GPU, drives and peripherals — should stay comfortably below this figure.

Is this unit compatible with the standard ATX interface in my case?

Yes, it follows the ATX form factor and provides the usual 24-pin main connector plus 8-pin CPU power, fitting standard ATX cases and motherboards.
