ATX power supply with 80 PLUS Gold efficiency

The KHACHIMO 241120.400 241120.200 is a new ATX power supply certified to the 80 PLUS Gold standard. It targets system builders who want high efficiency and low noise in a standard desktop chassis. The unit delivers clean power through a resonant LLC topology with DC-to-DC conversion.

Replacing older or uncertified units

This supply upgrades systems that currently run on lower-efficiency or non-modular power supplies. The jump is worth it when you need modern standby compatibility for faster wake-from-sleep behaviour and reduced coil whine. It also suits builds where silent operation at low and medium loads is a priority.

Limits of the ATX form factor and Gold rating

The ATX form factor restricts physical dimensions, so the unit must fit within standard case clearances. Gold certification guarantees efficiency at defined load points but does not promise specific noise levels under full load. Zero RPM fan mode operates only up to medium loads, so the fan will spin under heavier demand.

Questions about this item

Will the ATX form factor fit my standard desktop chassis?

Yes, the ATX type matches the mounting holes and rear cutout of any standard desktop case built to the ATX specification.

What is the most common mistake when installing this unit in a Modern Standby system?

Forgetting to connect the 4-pin or 8-pin CPU auxiliary cable; without it the motherboard cannot enter the low-power sleep states that Modern Standby requires.

How often should I clean the fan to keep Zero RPM mode working reliably?

Blow dust from the fan grille every six to twelve months; a clogged grille prevents the fan from stopping at low and medium loads.
