KHACHIMO 400W ATX Power Supply

The KHACHIMO SSG-550M-SH delivers 400 watts of continuous power through a standard ATX form factor. It is intended for desktop builders replacing a unit in an existing system or assembling a new office or entry-level gaming PC. Each unit is tested working before dispatch to confirm basic operation.

Thermals noise and power draw

The supply operates within typical ATX thermal limits for a 400W design, using its internal fan to move heat across the heatsink array. Under normal loads the fan runs at a low speed that stays quiet in a standard chassis. Power draw from the wall matches the connected components up to the rated 400W output.
