KHACHIMO 3020 7020 9020 3620 1700 8Pin 400W Power Supply

Ready for modern standby systems

This ATX power supply delivers 400 W and carries 80 PLUS Gold certification for high efficiency. It is designed for PCs that use Modern Standby so wake-from-sleep times stay extremely short and low-load efficiency is improved. The resonant LLC topology with DC-to-DC conversion provides clean power and enables deeper sleep states. Builders wanting silent idle operation will appreciate the Zero RPM fan mode.

Standard ATX fit with single 8-pin

The unit follows the ATX form factor so it mounts in typical cases using four screws. Only one 8-pin connector is mentioned in the model data, so systems needing multiple CPU or GPU power plugs will require adapters or a different unit. Cable routing is straightforward but the fixed cable set limits how far you can run wires behind the motherboard tray. Check your motherboard and graphics card power needs before installing.

Quiet under sustained load

At low and medium loads the fan remains off entirely, keeping noise near zero during everyday work. When output rises the fan spins up, and the resonant LLC design with DC-to-DC conversion reduces coil whine so the unit stays quiet even during longer sessions. Gold-rated efficiency means less waste heat, which helps internal temperatures stay lower over extended use. The fan will run continuously only under heavier sustained demand.
