Power for Modern Standby PCs

The KHACHIMO WepeX 1000B is a 1000W ATX power supply built for systems that use Modern Standby sleep states. It suits desktop builders who want fast wake times and high efficiency at low loads. The unit is new and carries 80 PLUS Gold certification for reduced power draw and heat output. It targets users who value quiet operation during typical workloads.

Quiet Build with Resonant LLC Design

A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine. This electrical layout also supports deeper, more energy-efficient sleep states. The ATX form factor fits standard chassis mounts without special brackets or adapters.

Limits of ATX and Gold Efficiency

The 80 PLUS Gold rating guarantees high efficiency at defined load points but does not promise a specific figure at every possible draw. Modern Standby benefits depend on motherboard and operating system support, not the power supply alone. Zero RPM mode engages only within a load range the unit controls internally. Builders needing redundant or server-grade features should look elsewhere.
