KHACHIMO EPW15-48A 800W ATX power supply

800W ATX power supply for modern PCs

The KHACHIMO EPW15-48A is an ATX form-factor unit built for desktop builders who want an 80 PLUS Gold certified supply with Modern Standby compatibility. It delivers 800W of continuous power through a resonant LLC topology with DC-to-DC conversion for clean voltage regulation. The zero RPM fan mode keeps the system silent at low and medium loads while enabling efficient sleep states.

80 PLUS Gold certified efficiency

The single specification that determines suitability is the 80 PLUS Gold certification, which guarantees high efficiency across typical loads for lower power draw, reduced heat and quieter operation. This efficiency level is the deciding factor for builders who prioritise energy savings and thermal headroom in their component selection. Without this rating the unit would not meet the same standard for sustained performance.

Handles mid-range to high-end single-GPU builds

An 800W capacity comfortably powers mainstream processors paired with a single high-performance graphics card and multiple drives while leaving headroom for transient spikes. It runs out when a system demands sustained loads beyond 800W such as dual flagship GPUs or extreme overclocking scenarios that exceed the rated output. The Modern Standby support also ensures fast wake times for compatible platforms.
