KHACHIMO 350W ATX power supply

This 350 watt ATX unit delivers 80 PLUS Gold certified efficiency for desktop PCs and workstations that need reliable power without excess capacity. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine for quieter operation. It suits builders who want efficient, dependable power for standard configurations.

ATX form factor with Gold efficiency

The ATX form factor fits standard cases and the 80 PLUS Gold rating means high efficiency operation for lower power consumption, less noise, and cooler temperatures during daily use. Zero RPM fan mode keeps the cooling fan completely off at low and medium loads for near-silent operation when the system is idle or under light workloads. Resonant LLC topology with DC-to-DC conversion further reduces audible noise and enables more energy efficient sleep states. Builders needing higher wattage or redundant power supplies should look elsewhere.

Efficient thermals with silent operation

High efficiency Gold certification reduces waste heat so the unit runs cooler under normal loads while drawing less power from the wall. Zero RPM fan mode eliminates fan noise entirely at low and medium loads, activating the fan only when thermal conditions require active cooling. The resonant LLC topology with DC-to-DC conversion minimises coil whine for quieter overall operation and supports efficient sleep states. Systems with sustained heavy loads will engage active cooling as needed.
