450W ATX Power Supply

The KHACHIMO DS450-3-001 delivers 450W of continuous power for standard desktop builds. It targets system integrators and home users who need reliable energy delivery for office or mid-range gaming configurations. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The unit suits builds that prioritise efficient power conversion over extreme wattage headroom.

80 PLUS Gold Certified Build

Gold certification confirms high efficiency operation that reduces power consumption, noise output and operating temperatures. Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine for quieter performance. This topology also enables more energy efficient sleep states during idle periods. The ATX form factor fits standard chassis mounts without proprietary brackets or adapters.

Zero RPM Fan Mode Thermals

A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Fan activation occurs only when thermal conditions demand active airflow, keeping acoustic output minimal during typical desktop tasks. High efficiency conversion produces less waste heat, contributing to cooler internal case temperatures. The design supports stable voltage regulation across varying load conditions without audible coil whine.
