KHACHIMO JCI-4511F-1M1 300W 80 PLUS Gold power supply

300 W ATX power supply

This 300 W ATX power supply delivers 80 PLUS Gold certified efficiency for industrial and embedded systems. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. The unit suits compact builds that demand reliable, efficient power delivery.

Replacing lower-efficiency or noisy units

Upgrading from a standard Bronze or unrated supply cuts power draw, lowers heat output and reduces acoustic noise. The jump is worth it when your system runs continuously or sits in noise-sensitive environments. Zero RPM fan mode eliminates fan noise entirely at low and medium loads. Resonant LLC topology further supports energy-efficient sleep states for always-on deployments.

Silent, efficient power for compact systems

This supply fits builders who need 80 PLUS Gold efficiency, near-silent operation and Modern Standby support in an ATX form factor. Buyers who require higher wattage for multi-GPU configurations or heavy overclocking should look at something else. Systems needing redundant or hot-swap power modules will not be served by this single-unit design. The 300 W rating also limits use in high-end workstation builds.
