300W ATX Gold unit for compact builds

The KHACHIMO DL20 G9 is a 300 watt ATX power supply certified 80 PLUS Gold, designed for small-form-factor desktops that need reliable power without excess capacity. It suits office refreshes, thin-client replacements and quiet home PCs where a full-size unit would waste space and budget.

Standard ATX fit with semi-passive cooling

Installation follows normal ATX mounting points and connector layout, so it drops into any compliant chassis without adapters. The Zero RPM fan mode stops the fan completely at low and medium loads, eliminating a common source of noise; the only typical issue is cable reach in deeper cases where the fixed-length leads may fall short of the motherboard header.

Steady output with LLC resonant topology

Under sustained load the resonant LLC design with DC-to-DC conversion keeps voltage regulation tight and suppresses coil whine, while the Gold-rated efficiency curve reduces waste heat during long sessions. Modern Standby support lets the system enter deeper sleep states and wake almost instantly, so the supply stays cool and quiet even when the PC idles for hours.

Questions about this item

How can I confirm the 80 PLUS Gold efficiency is active after installing the DL20 G9?

The unit meets 80 PLUS Gold certification, so it will draw less power and run cooler; you can verify efficiency by comparing wall draw to component load with a power meter.

What cables come with the 300 W ATX supply and what must I source separately?

The box includes the PSU unit and standard ATX cables; any proprietary HP connectors such as the S14-300P1A pinout must be sourced separately if your chassis requires them.

Which version of the DL20 G9 should I choose for a Modern Standby build?

The single 300 W model listed supports Modern Standby with fast wake times and Zero RPM fan mode, so no other capacity or version selection is needed.
