300W ATX Power Supply

The KHACHIMO D12-300P1A delivers 300W of continuous power in a standard ATX form factor. It targets system builders assembling office workstations, home PCs or entry-level configurations where moderate power draw and high efficiency matter more than maximum wattage.

Modern Standby and Zero RPM Mode

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. The Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation during typical desktop use.

Resonant LLC Topology and Gold Efficiency

Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine and supporting energy-efficient sleep states. The 80 PLUS Gold certification confirms high efficiency operation for lower power consumption, less noise and cooler temperatures.

商品問答

Will the fan need replacement after long-term use?

The Zero RPM Fan Mode stops the fan at low and medium loads, reducing mechanical wear and extending its service life.

What limits sustained output at full load?

The 300 W rating is the maximum continuous power the unit can deliver; exceeding it triggers protection shutdown.

How loud and hot does it get when running all day?

80 PLUS Gold efficiency and Zero RPM Fan Mode keep heat and noise low, with the fan staying off until higher loads are reached.
