KHACHIMO AT350-24V-48B 280W ATX power supply

280 W ATX power supply

This KHACHIMO ATX unit delivers 280 W of continuous power for compact desktop builds. It targets system integrators and DIY builders who need an efficient, quiet supply for mainstream components. The 80 PLUS Gold certification ensures high efficiency across typical loads, reducing heat and electricity cost. Modern Standby compatibility allows extremely fast wake-from-sleep times for responsive daily use.

Build integration and cable headroom

The supply fits standard ATX mounting points and uses a DC-to-DC conversion stage to provide clean voltage regulation for modern CPU and GPU power phases. Zero RPM fan mode keeps the system near-silent at low and medium loads, freeing acoustic headroom for quiet workstations. Resonant LLC topology reduces coil whine and supports deeper sleep states without extra configuration. AC 220 V input suits regions with that mains voltage.

Capacity limits and suitable workloads

At 280 W the unit comfortably handles mid-range processors and entry-level discrete graphics during sustained workloads. It runs out of headroom when paired with high-end GPUs or heavily overclocked CPUs that push total system draw beyond the rated output. Builders who need more power for multi-GPU arrays or extreme overclocking should select a higher-wattage model. The 24 V and 48 B designations in the model code reflect internal rail organisation rather than external connectors.
