KHACHIMO 250W ATX Power Supply

The KHACHIMO SS-250TFX is a 250W ATX power supply built for compact or low-power desktop builds. It carries 80 PLUS Gold certification for high efficiency and lower running costs. Modern Standby support enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine.

Suited for basic office PCs

This unit fits builders assembling energy-efficient workstations or home office machines that stay well within a 250W envelope. The Zero RPM fan mode keeps acoustics near silent at low and medium loads. It is not for gaming rigs, workstations with discrete graphics cards, or any build whose peak draw exceeds the rated output. Buyers needing higher wattage or multiple PCIe power connectors should look elsewhere.

Integrates into ATX cases with standard cabling

The ATX form factor allows installation in compatible chassis using the included cables. High efficiency reduces waste heat, easing the burden on case airflow. Modern Standby compatibility frees the system to enter deeper sleep states without losing responsiveness. Ensure the total system power demand remains within the 250W limit for stable operation.

商品問答

What motherboard power connector does the 250W ATX supply need to function?

The unit uses a standard ATX form factor, so it requires a 24-pin main connector and a 4-pin or 8-pin CPU power connector from the motherboard.

Will the Zero RPM Fan Mode activate with legacy components that draw little power at idle?

Yes, the fan stops completely at low and medium loads, so older hardware that idles at modest wattage will keep the supply silent.

How can I verify the 80 PLUS Gold efficiency is active after installation?

Monitor AC wall draw versus DC load with a power meter; the supply should maintain Gold-level efficiency across typical operating ranges.
