KHACHIMO 400W ATX Power Supply DPS-400AB-12H

400W ATX Power Supply

The KHACHIMO DPS-400AB-12H is a 400W ATX power supply built for modern desktop systems. It supports Modern Standby for extremely fast wake-from-sleep times and improved low-load efficiency. The unit targets builders who need reliable power for standard components and value quiet operation. It is not suited for configurations requiring higher total output or multiple high-end graphics cards.

80 PLUS Gold Efficiency

Rated at 400 watts, the supply delivers continuous power with 80 PLUS Gold certified efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, consistent voltage regulation across the rails. This design reduces energy waste and helps maintain stable operation under typical loads. Headroom diminishes quickly when several power-hungry devices are added simultaneously.

Zero RPM Fan Mode

At low and medium loads the cooling fan stops completely, enabling near-silent operation during everyday tasks. The same topology that enables Zero RPM mode also reduces coil whine for quieter performance overall. Efficient conversion keeps internal temperatures lower, so the fan spins less often and at lower speeds when active. Heavy sustained loads will eventually require active cooling.
