1100W ATX Power Supply with Gold Efficiency

This KHACHIMO ATX power supply delivers 1100W of continuous power for high-performance desktop builds. It carries 80 PLUS Gold certification for efficient energy conversion and reduced heat output. Modern Standby compatibility enables extremely fast wake-from-sleep times. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power delivery.

Suitable for Quiet High-Power Systems

The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. LLC resonant topology reduces coil whine for quieter performance. Builders who need a lower wattage unit for a compact or budget system should look at a different capacity. Users requiring a non-ATX form factor such as SFX or TFX will not be able to install this unit.

80 PLUS Gold Certified Efficiency

The 80 PLUS Gold certification confirms high efficiency operation across typical loads. This results in lower power consumption, less noise, and cooler temperatures inside the case. The resonant LLC topology with DC-to-DC conversion supports more energy efficient sleep states. These characteristics define whether this power supply meets the efficiency and acoustic targets of the build.
