KHACHIMO 1100W ATX Power Supply FSJ017 SP57A14698

1100W ATX Power Supply for Demanding Builds

This KHACHIMO unit delivers 1100 watts of continuous power through an ATX form factor, making it suitable for high-end desktop systems with multiple graphics cards or power-hungry processors. The 80 PLUS Gold certification confirms high efficiency across typical load ranges, reducing waste heat and operating cost. It targets enthusiasts and workstation users who need reliable headroom for sustained workloads. Builders requiring less capacity or a smaller footprint should consider lower-wattage alternatives.

Sustained Load Behaviour with LLC Resonant Topology

The resonant LLC topology combined with DC-to-DC conversion maintains tight voltage regulation during prolonged heavy loads, minimising ripple and preventing coil whine. This design supports stable output when the system runs at high utilisation for extended periods, such as rendering or compute tasks. Efficiency remains high across the curve, so power draw from the wall stays predictable. The platform handles continuous demand without the voltage drift seen in simpler designs.

Thermals Noise and Power Draw in Normal Use

At low and medium loads the Zero RPM fan mode keeps the cooling fan completely stationary, delivering near-silent operation during everyday tasks. When the fan does engage, the high efficiency of the 80 PLUS Gold design means less waste heat to dissipate, allowing lower fan speeds and quieter acoustics. Modern Standby compatibility enables extremely fast wake-from-sleep transitions while maintaining low idle power consumption. The result is a cool, quiet power supply that scales its noise output to actual demand.
