What this PSU is

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

Suits office PCs, home-theatre builds and compact workstations that value silent operation and high efficiency at modest loads. Not for gaming rigs or workstations that need more headroom, multiple GPU power cables or higher continuous wattage.
