The KHACHIMO SP400-A is a 400W ATX power supply built with Resonant LLC topology and DC-to-DC conversion for clean, consistent output. It carries 80 PLUS Gold certification, Zero RPM fan mode and Modern Standby compatibility for fast wake times and low-load efficiency.

Check your build first

Verify that your system power draw stays within the 400W rating and that your case accepts a standard ATX unit. Confirm the included cable set covers your motherboard, CPU and graphics connectors before ordering.

Who it suits and who it doesn't
