  • 350 W ATX power supply supports standard desktop builds with reliable output

Compact ATX PSU for Efficient Builds

The KHACHIMO PSR350-D is a 350 W ATX power supply built for mainstream desktop systems. It carries 80 PLUS Gold certification, delivering high efficiency that reduces energy waste and keeps internal temperatures lower. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Suited for Standard Desktops, Not High-Power Rigs

This unit suits office PCs, home workstations and modest gaming builds that stay within its 350 W rating. The resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine. Builders planning multi-GPU configurations or components with very high peak power draw should consider a higher-capacity power supply instead.

350 W Rating Sets the Power Limit

The single specification that decides fit is the 350 W maximum output. Every component in the system must draw less than this total under full load. Check the combined power requirements of your CPU, graphics card, drives and peripherals before choosing this model.

Questions about this item

How do I install this ATX power supply and what step is often missed?

Secure the unit with four screws, attach the 24-pin ATX and 8-pin CPU connectors, then confirm the Zero RPM fan mode engages at low load for silent operation.

What maintenance will this 350W PSR350-D need over time?

Periodically clear dust from the intake grille with compressed air; the fan bearings are sealed and the Zero RPM mode reduces wear, so no lubrication or fan replacement is expected.

What limit appears first during sustained heavy loads on this 80 PLUS Gold unit?

The 350 W continuous output ceiling is reached before thermal limits, triggering over-power protection if exceeded.
