KHACHIMO 250W ATX Power Supply

This KHACHIMO ATX power supply delivers 250W of continuous power for desktop systems. It carries 80 PLUS Gold certification for high-efficiency operation and lower running temperatures. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The unit uses resonant LLC topology with DC-to-DC conversion for clean, consistent power delivery.

Suits Modern Standby builds and quiet offices

The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion reduces coil whine and supports energy-efficient sleep states. Builders needing higher wattage for multi-GPU configurations or power-hungry workstations should look at higher-capacity units instead.

80 PLUS Gold efficiency at 250W

Gold-rated efficiency cuts power waste, reduces heat output and lowers system noise across typical workloads. The 250W rating defines the maximum continuous output available for components. Verify that your platform's total power draw stays within this limit before purchasing.

Questions about this item

Does the KHACHIMO 250W ZT6303 include cables or must they be bought separately?

The unit is supplied as the power supply only; any ATX cables required for your build must be sourced separately.

Which capacity should I choose when the supplier lists CPA 250-4530S181?

The part number identifies a single 250W model, so there is no alternative capacity to select.

What does the 80 PLUS Gold rating mean for daily use in my PC?

It guarantees high efficiency at typical loads, reducing power draw, heat output and fan noise compared with lower-rated units.
