KHACHIMO HWS100A 5V 20A 100W power supply

KHACHIMO HWS100A ATX Power Supply

The KHACHIMO HWS100A is a new ATX power supply rated at 100W delivering 5V at 20A. It targets system builders needing a compact, efficient unit for low-power configurations such as embedded PCs or small-form-factor workstations.

Capacity and Headroom

The 100W capacity comfortably handles low-load platforms and idle states while maintaining 80 PLUS Gold efficiency. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Headroom disappears quickly if the build adds discrete graphics or multiple drives.

Build Quality and Connectors

Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine. The Zero RPM fan mode stops the cooling fan at low and medium loads for near-silent operation. Standard ATX mounting and cabling integrate directly into compatible chassis without adapters.
