KHACHIMO BTX A4800C S2000i S3041i 300W Power Supply

300 W ATX Power Supply for Modern Standby PCs

This 300 W ATX unit is built for systems that rely on Modern Standby sleep states. The 80 PLUS Gold certification and resonant LLC topology with DC-to-DC conversion deliver efficient, stable power for daily workloads and low-load idle periods.

Verify ATX fit and connector layout before ordering

Confirm your chassis accepts a standard ATX form factor and that your motherboard uses compatible power connectors. The unit’s Modern Standby support requires a matching platform to enable the fast wake-from-sleep behaviour.

Gold efficiency with semi-passive cooling

Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. The resonant LLC design reduces coil whine while supporting deeper, more energy-efficient sleep states day to day.
