350W 1U Gold PSU

The KHACHIMO PWS-351-1H is a new 350 watt ATX power supply built to the 1U form factor and rated 80 PLUS Gold. It uses Resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power and reduce coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Server builders and silent PC users

This unit suits rack-mount servers, compact workstations or quiet desktop builds that need a 1U Gold-rated supply with a Zero RPM fan mode for near-silent operation at low and medium loads. It is not for systems that require more than 350 watts of continuous power or a standard ATX-height chassis.

80 PLUS Gold efficiency

The single specification that decides fit is the 80 PLUS Gold certification, which guarantees high-efficiency operation for lower power consumption, less noise and cooler temperatures across the load range.
