KHACHIMO R310 350W ATX PSU

The KHACHIMO R310 is a 350 W ATX power supply built for mainstream desktop builds that need reliable, efficient power. It suits office workstations, home PCs and light gaming rigs where a compact, quiet unit is preferred. Buyers who need more than 350 W for multi-GPU setups or high-end workstations should look elsewhere.

80 PLUS Gold and Modern Standby

The unit meets 80 PLUS Gold efficiency, reducing waste heat and lowering electricity use at typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. It does not support higher 80 PLUS tiers or server-grade redundancy features.

Resonant LLC with DC-to-DC and Zero RPM

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine and enabling efficient sleep states. The Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. Under sustained heavy loads the fan will spin and headroom above 350 W is not available.

  • 80 PLUS Gold certified efficiency cuts power draw and heat
  • Zero RPM fan mode stops the fan at low loads
