  • TypeATX
  • Modern Standby compatibility for near-instant wake from sleep

Purpose and Audience

The KHACHIMO 250W ATX power supply is built for compact systems that need reliable, efficient power delivery. It suits office PCs, home-theatre builds and entry-level workstations where a lower wattage unit keeps cabling tidy and heat output low. Buyers who require more than 250 watts for discrete graphics cards or high-core-count processors should look at higher-capacity units.

Build Integration

The unit follows the standard ATX form factor so it fits most mainstream chassis and works with common motherboard power connectors. Its Resonant LLC topology with DC-to-DC conversion delivers clean voltage regulation, which helps stable operation during modern sleep states. The 80 PLUS Gold certification means less waste heat, easing the cooling burden on the rest of the build.

Thermals Noise and Power

Zero RPM fan mode stops the fan completely at low and medium loads, giving near-silent running during typical desktop tasks. When the fan does spin, the high-efficiency design keeps temperatures lower than less efficient units. The 80 PLUS Gold rating confirms reduced power draw at the wall, contributing to cooler, quieter operation overall.

Questions about this item

Will the 250 W continuous rating handle a modern CPU and GPU under sustained load?

The unit delivers 250 W total output; sustained heavy loads that approach or exceed this limit will trigger protection shutdown.

How loud and hot does the power supply get when running all day?

Zero RPM mode stops the fan at low and medium loads for silent operation; 80 PLUS Gold efficiency reduces waste heat, keeping temperatures lower during extended use.

What cables or connectors must my build already have for this PSU to work?

As an ATX-type supply it provides standard motherboard, CPU and peripheral connectors; your case must accept an ATX form-factor unit and your components must use standard ATX power plugs.
