KHACHIMO GWCR-1200D 1200W ATX power supply

High-output ATX unit

The KHACHIMO GWCR-1200D is a 1200W ATX power supply built for systems that draw sustained heavy loads. It targets workstations and high-end gaming rigs where multiple GPUs or dense storage arrays demand a large, single-rail reservoir. Builders who need a second card or more storage than a mid-range unit can support will find the headroom useful. It is not for compact chassis that cannot fit a full-size ATX PSU.

Verified build and standard connectors

Each unit is test working before it ships, confirming that the internal soldering and protection circuits function as intended. The ATX form factor means it mounts in any standard tower case using the usual four screw holes. Native 24-pin, EPS and PCIe leads plug directly into modern motherboards and graphics cards without adapters. Cable routing stays straightforward because the connector layout follows the established ATX pinout.

Practical limits of the ATX 1200W class

The 1200W rating represents the maximum combined continuous output the platform can deliver within ATX specification limits. Transient spikes above that level will trigger over-current protection and shut the unit down. Efficiency and thermal behaviour follow the constraints of the switching topology used in this class. First listed by the manufacturer in 2024, the design reflects current ATX guidelines but does not extend beyond the standard's defined power envelope.
