KHACHIMO

KHACHIMO PAC-2200WB 2247W power supply

SKU CH-YGME-2K1P3

An 80 PLUS Gold ATX power supply delivering 2247 W with Modern Standby support, Zero RPM fan mode and resonant LLC topology for quiet, efficient operation

  • TypeATX
  • 80 PLUS Gold certification cuts power draw and heat
  • Zero RPM fan mode stops the fan at low load for silent running
  • Modern Standby support gives faster wake-from-sleep and better idle efficiency
  • Resonant LLC with DC-to-DC conversion delivers clean power and reduces coil whine
  • 2247 W maximum output handles demanding multi-GPU systems

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.

Questions about this item

What does the 2247 W rating mean for a working system?

The unit can deliver up to 2247 W of continuous power to all rails combined, so it supports multi-GPU workstations or servers with very high total draw.

Which ATX standard does this PSU follow and what does it limit?

It is an ATX-type supply, so it fits the standard ATX mounting pattern and uses the usual 24-pin, EPS and PCIe connectors defined by that form factor.

What clearance and mounting does the PAC-2200WB need?

The PSU uses the regular ATX mounting holes and depth, so it fits any case designed for a standard ATX power supply.
