KHACHIMO 500W ATX Power Supply

This 500W ATX unit is designed for QNAP NAS systems and compatible desktop builds requiring reliable, efficient power delivery. It suits users who prioritise low standby consumption and quiet operation in always-on environments. Builders needing higher wattage or modular cabling for custom loops should look elsewhere.

80 PLUS Gold Efficiency and Zero RPM Fan

The 80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and lowering overall power draw. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion further minimises coil whine and supports deeper sleep states.

Modern Standby Compatibility and Clean Power

Modern Standby support enables extremely fast wake-from-sleep times and improved low-load efficiency for always-ready systems. The DC-to-DC conversion architecture delivers clean, consistent voltage to sensitive NAS components. No extra software or accessories are bundled beyond the standard power cables.

Perguntas sobre este artigo

How do I install this 500W ATX power supply in a QNAP NAS, and what step is often missed?

Mount the unit in the chassis, connect the 24-pin ATX and CPU power cables firmly, then enable Modern Standby in the NAS BIOS so the fast wake-from-sleep feature actually works.

What maintenance or replacement will this PSU need over time?

The Zero RPM fan bearings are the only moving part; clean dust from the intake annually and replace the fan if it develops noise or stops spinning under load.

What limit appears first during sustained heavy load on this 500W Gold unit?

At continuous loads near 500W the fan exits Zero RPM mode and spins up; if case airflow is restricted, internal temperatures will hit the protection threshold and throttle output.
