KHACHIMO PSR450-12A1 450W ATX Power Supply

Capacity & Certification

The KHACHIMO PSR450-12A1 is a 450W ATX power supply built for modern desktop PCs. It carries 80 PLUS Gold certification for high efficiency, lower power draw, and reduced heat output. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. This unit suits builders wanting reliable, efficient power for standard components.

Upgrade Path

This supply replaces older, less efficient units that lack Modern Standby support or Gold-rated efficiency. The jump is worth it when your current PSU cannot maintain stable voltages under load or runs its fan constantly at idle. Resonant LLC topology with DC-to-DC conversion delivers cleaner power and reduces coil whine. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation.

Compatibility Check

Verify your case accepts a standard ATX form-factor power supply before ordering. Confirm the motherboard requires a 24-pin ATX connector and that your CPU and GPU power cables match the unit's fixed outputs. Ensure the 450W capacity covers the total system draw of your chosen components. The fixed cable design means you cannot remove unused connectors for cable management.
