300W ATX power supply for modern standby systems

This 300W ATX unit delivers 80 PLUS Gold certified efficiency and is built for Modern Standby compatibility. The Resonant LLC topology with DC-to-DC conversion provides clean power for stable operation. It suits builds that prioritise low power draw and fast wake-from-sleep responsiveness.

Zero RPM fan mode changes daily acoustics

At low and medium loads the cooling fan stops completely, removing audible noise from the system. This behaviour pairs with the high-efficiency design to keep temperatures lower without active cooling. The result is near-silent operation during typical desktop or idle workloads.

300W rating limits high-power configurations

The 300W maximum output restricts use to low-power CPUs and graphics cards without auxiliary power connectors. Builds requiring multiple drives, discrete GPUs or heavy overclocking will exceed this capacity. The ATX form factor fits standard cases but the wattage ceiling defines the practical component ceiling.

Questions about this item

Will the cooling fan on this KHACHIMO Bronze 300W unit need replacement after years of continuous use?

The Zero RPM Fan Mode stops the fan entirely at low and medium loads, so the bearing only spins under heavier demand, extending its service life.

What component limit appears first when this power supply runs at full load for long periods?

The 300 W maximum output is the hard ceiling; sustained draws above that will trigger protection and shut the unit down.

How much noise and heat does this PSU produce when it powers a workstation all day?

At typical workloads the fan stays off for near-silent running, while 80 PLUS Gold efficiency keeps waste heat and power draw low.
