KHACHIMO PWS-1K27A-1R 1200W ATX power supply

High-wattage ATX power supply

The KHACHIMO PWS-1K27A-1R delivers 1200W of continuous power for high-end desktop builds. Its 80 PLUS Gold certification ensures high efficiency, reducing waste heat and lowering overall system power draw. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. This unit targets enthusiasts building workstations or gaming rigs with demanding multi-GPU configurations.

Build integration and cable management

The ATX form factor fits standard chassis designs while the resonant LLC topology with DC-to-DC conversion provides clean, consistent power to sensitive components. This topology reduces coil whine and supports energy-efficient sleep states for quieter operation. Builders gain a high-capacity foundation that frees headroom for future upgrades without needing to replace the power supply. The design suits systems where stable delivery under heavy load is critical.

Cooling behaviour and acoustic profile

Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation during everyday tasks. The fan engages only when thermal demand rises, balancing acoustics with component longevity. This behaviour complements the Gold-rated efficiency by minimising unnecessary airflow noise. Users who prioritise a quiet workspace or bedroom PC benefit directly from the semi-passive cooling approach.
