  • 80 PLUS Gold efficiency cuts power draw and heat

What this 210 W ATX unit does

The KHACHIMO 4.2V 50A 210W ATX power supply delivers up to 210 watts for modest desktop builds and compact systems. It targets users who want a new, efficient unit without excess capacity. Builders needing higher output for multi-GPU rigs or heavy overclocking will need a larger unit.

Efficiency and heat under continuous load

80 PLUS Gold certification means the supply runs at high efficiency across typical loads, lowering electricity draw and reducing waste heat. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight during sustained work, while Modern Standby compatibility allows deeper sleep states and rapid wake times.

Quiet build and practical connectors

Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation, and the same topology reduces coil whine. Standard ATX form factor fits most cases, and the included cable set covers mainstream motherboard, CPU, and peripheral connections.

Questions about this item

How loud is the 210W unit when it runs all day?

At low and medium loads the fan stops completely, and 80 PLUS Gold efficiency keeps waste heat low for quieter operation.

What cables or connectors must I already have for this ATX supply?

Standard ATX motherboard and peripheral connectors are required; the unit uses the usual ATX pinout.

Will the 4.2V 50A rail work with older components I keep?

The DC-to-DC design delivers clean power on the 4.2V rail, and Modern Standby support lets older parts use efficient sleep states.
