KHACHIMO 2200W ATX Power Supply CDR-2221-2M1

High-capacity ATX supply for demanding builds

The KHACHIMO CDR-2221-2M1 delivers 2200W of continuous power in a standard ATX form factor. It is aimed at workstations and multi-GPU configurations that draw sustained current well beyond typical consumer limits. The unit supports Modern Standby for rapid wake-from-sleep and improved low-load efficiency. Builders needing a single high-wattage rail will find the output suitable for heavy compute loads.

Sustained output with resonant LLC topology

Under prolonged load the resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation and clean power delivery. This design reduces ripple and coil whine while supporting energy-efficient sleep states during idle periods. The 80 PLUS Gold certification confirms high efficiency across the load range, lowering waste heat during extended rendering or compute sessions. Performance remains consistent without the voltage droop seen in lesser topologies.

Quiet thermal profile with zero-RPM mode

At low and medium loads the cooling fan stops completely, eliminating audible noise for near-silent desktop operation. When the fan engages, the efficient Gold-rated platform keeps temperatures lower, allowing the fan to spin slower than on lower-efficiency units. Reduced heat output also eases case airflow requirements in dense builds. The combined topology and fan strategy minimise acoustic intrusion in noise-sensitive environments.
