350W ATX PSU for Modern Standby PCs

This KHACHIMO 9272C unit delivers 350 watts through an ATX form factor and carries 80 PLUS Gold certification for high efficiency. It is built for systems that use Modern Standby, offering extremely fast wake-from-sleep times and better low-load efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine.

Gold efficiency limits at low and high load

The 80 PLUS Gold standard guarantees high efficiency at typical loads, but efficiency drops outside the certified range. At very light loads the unit enters a low-power state rather than maintaining peak conversion rates. Builders should verify that the 350W maximum output matches their component peak draw before committing.

Zero RPM fan and quiet topology daily impact

A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. The resonant LLC design with DC-to-DC conversion further reduces coil whine, contributing to a quieter desktop experience. The ATX mounting pattern fits standard chassis layouts without modification.
