400W ATX power supply for efficient builds

This KHACHIMO H47107 unit delivers 400 watts of continuous power in a standard ATX form factor. It targets system builders who want reliable energy delivery without excess capacity. The 80 PLUS Gold rating confirms high efficiency across typical loads, reducing waste heat and electricity draw.

Upgrade from lower-efficiency or noisy units

Replacing an older Bronze-rated or uncertified supply cuts power loss and enables Modern Standby for faster wake times. The jump is worthwhile when your current unit lacks DC-to-DC conversion or runs its fan constantly at idle. Builders staying within a 400 W envelope gain cleaner rails and quieter operation without over-provisioning.

Fits standard ATX cases

The resonant LLC topology with DC-to-DC conversion provides stable voltages for modern sleep states, so the board and firmware must support those states to benefit. Zero RPM mode keeps the fan off at low and medium loads, freeing acoustic headroom for GPU or CPU coolers. Ensure your case accepts a regular ATX power supply and that your component peak draw stays within the rated output.

Questions about this item

What ATX case clearance does the H47107 400W PSU require?

The unit follows the standard ATX form factor, so any case with a regular ATX power-supply bay will accept it without modification.

Which cables must be connected during installation to enable Modern Standby?

Attach the 24-pin motherboard connector and the 4+4-pin CPU power cable; the PSU then supports the low-power sleep states automatically.

How do I clean the fan on the H47107 after extended use?

Power off the system, remove the PSU, and blow compressed air through the fan grille to clear dust from the Zero RPM fan assembly.
