KHACHIMO PSR350-AN 350W 80 Plus Gold ATX power supply

350W ATX Gold power supply for modern PCs

This 350 watt ATX unit delivers 80 Plus Gold efficiency for lower power draw and cooler running. It targets builders who need reliable energy for mainstream desktops and workstations. Modern Standby support enables extremely fast wake-from-sleep times and better low-load efficiency. The compact form factor fits standard ATX cases without modification.

Upgrade from older Bronze or unrated units

Replacing an older Bronze or unrated supply with this Gold model cuts waste heat and reduces coil whine through resonant LLC topology with DC-to-DC conversion. The efficiency jump is worth it when electricity costs matter or when a system runs for long periods at low load. Zero RPM fan mode keeps the unit silent during light workloads. Buyers who need more than 350 watts for multi-GPU or high-end CPU configurations should look elsewhere.

Straightforward ATX installation

Installation follows the usual ATX procedure: mount the unit, connect the 24-pin motherboard and CPU power cables, then attach drive and peripheral leads. The fully wired harness means no modular cables to misplace, but it also leaves unused connectors inside the case. Cable stiffness can make routing tight behind the motherboard tray in smaller chassis. Ensure the fan orientation matches your case airflow design for optimal Zero RPM performance.
