KHACHIMO 300W 80 PLUS Gold ATX Power Supply

Modern Standby Ready 300W ATX Unit

This 300 watt ATX power supply is built for compact desktop systems that must meet Modern Standby requirements. It delivers fast wake-from-sleep performance and strong low-load efficiency for everyday office or home PCs. The 80 PLUS Gold rating ensures high conversion efficiency across typical workloads. It suits builders who need a compliant unit for small form factor cases.

Sustained Load Behaviour with LLC and DC-to-DC

Under continuous demand the resonant LLC topology paired with DC-to-DC conversion keeps voltage regulation tight and ripple low. The design maintains clean, consistent power output without the voltage drift seen in simpler group-regulated units. Coil whine is reduced even when the supply runs near its rated capacity for long periods. This topology also enables deeper, more efficient sleep states during idle intervals.

Zero RPM Fan Mode and Thermal Profile

At low and medium loads the cooling fan stops completely, providing near-silent operation for quiet environments. When load rises the fan spins up only as needed, keeping temperatures controlled without unnecessary noise. The 80 PLUS Gold efficiency reduces waste heat, so the unit runs cooler than lower-rated alternatives under the same power draw. This balance suits noise-sensitive builds where acoustic comfort matters.
