KHACHIMO PAC-2200WB 2247W power supply

High-wattage ATX power supply

The KHACHIMO PAC-2200WB delivers up to 2247 W of continuous power from a standard ATX form factor. It is aimed at builders assembling dual-GPU workstations, render farms or extreme overclocking rigs that demand sustained heavy loads. Buyers who only need a single mid-range graphics card will find this unit far larger than necessary.

80 PLUS Gold efficiency rating

Certification at the 80 PLUS Gold level means the supply meets strict efficiency targets across typical load ranges, reducing waste heat and electricity cost. Resonant LLC topology with DC-to-DC conversion further tightens voltage regulation and supports modern low-power sleep states. Systems that cannot utilise the full 2200 W headroom will still benefit from the quieter, cooler operation.

Standard ATX installation with semi-passive cooling

The unit fits any ATX-compatible chassis and uses conventional 24-pin, EPS and PCIe connectors for straightforward cabling. A Zero RPM fan mode stops the fan completely at low and medium loads, eliminating noise during idle or light work. Installers must verify that their case provides enough depth for the PSU length and that the motherboard supports Modern Standby wake functions.
