KHACHIMO DX100 DX200 DX500 S3 Power Supply

ATX power supply for modern standby systems

The KHACHIMO DX100 DX200 DX500 S3 is an ATX power supply built for PCs that use Modern Standby sleep states. Its 80 PLUS Gold certification means high efficiency across typical loads, reducing waste heat and keeping fan speeds low. The resonant LLC topology with DC-to-DC conversion delivers clean, stable voltage rails for reliable component operation. This unit suits builders who want efficient, quiet power for contemporary desktop platforms.

Zero RPM fan mode and resonant LLC topology

A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation during everyday tasks. The resonant LLC topology with DC-to-DC conversion minimises coil whine and supports deeper, more energy-efficient sleep states. Together these features change the acoustic profile of the build, making the power supply virtually inaudible when the system is idle or under light use. This benefits users who prioritise a quiet computing environment.

80 PLUS Gold efficiency rating

The single specification that determines suitability is the 80 PLUS Gold efficiency rating, which guarantees high conversion efficiency at 20, 50 and 100 per cent load. Buyers who need a lower efficiency tier or who are building a system without Modern Standby support may find this unit exceeds their requirements. Ensure your motherboard and case support standard ATX dimensions before purchase.
