KHACHIMO HK300-11UAP 200W ATX 80 PLUS Gold Power Supply

1U 200W ATX Gold Supply

This KHACHIMO HK300-11UAP is a 1U form-factor ATX power supply rated at 200W. It targets builders of compact servers, thin clients, or small-form-factor workstations where rack height is limited to a single unit. The 80 PLUS Gold certification ensures efficient conversion for always-on or frequently sleeping systems. It is not suited for builds requiring more than 200W of continuous DC output.

Capacity and Headroom

The unit delivers up to 200W across its rails, which comfortably handles low-power CPUs, integrated graphics, and a handful of storage drives in a 1U chassis. At higher loads the fan engages to maintain thermal limits, and the Gold rating keeps waste heat low across the load range. Systems with discrete graphics cards or many drives will exceed the available headroom.

Bundled Features Impact

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency for always-connected workflows. The Zero RPM mode stops the fan entirely at low and medium loads, yielding near-silent operation in quiet environments. Resonant LLC topology with DC-to-DC conversion supplies clean power, reduces coil whine, and supports deeper sleep states.
