What this PSU delivers

The KHACHIMO NEC GT110b is a 400W ATX power supply built for mainstream desktop builds. It carries 80 PLUS Gold certification for high efficiency at typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. This unit suits builders who want reliable power without excess capacity.

How it fits your build

The ATX form factor slots into standard cases and works with common motherboard power connectors. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine for quieter operation. It frees up thermal headroom by running cooler at load. Builders needing higher wattage for multi-GPU setups or extreme overclocking should look elsewhere.

Behaviour under sustained load

Zero RPM fan mode keeps the cooling fan off at low and medium loads for near-silent operation. Under sustained demand the fan spins up only as needed while 80 PLUS Gold efficiency keeps power draw and heat low. The topology supports more energy efficient sleep states during long idle periods. It is not designed for continuous maximum output in high-ambient environments.

Perguntas sobre este artigo

What is the first limit reached under sustained full load?

The 400 W rated output is the first limit reached under sustained full load.

How does noise and heat behave when the unit runs all day?

Zero RPM fan mode stops the fan at low and medium loads for near-silent operation, while 80 PLUS Gold efficiency reduces waste heat and keeps temperatures lower during continuous use.

What must the buyer already own for this power supply to work?

An ATX-compatible case and motherboard with standard 24-pin and CPU power connectors are required for installation.
