420W ATX power supply

The KHACHIMO GIN-3420V delivers 420 watts of continuous power in a standard ATX form factor. It suits mainstream desktop builds that require reliable energy delivery for everyday computing tasks. The unit meets the needs of office workstations, home PCs and light gaming rigs where extreme headroom is not required. Builders seeking higher wattage for multi-GPU configurations will need a larger unit.

Gold efficiency with semi-passive cooling

80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat and keeping internal temperatures lower. A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation during office work or media playback. Resonant LLC topology with DC-to-DC conversion supplies clean, stable voltage rails and minimises coil whine. The ATX layout ensures compatibility with standard chassis mounting points and cable routing.

Modern Standby support for instant wake

Modern Standby compatibility allows the system to resume from sleep almost instantly while maintaining very low power draw. This behaviour improves the daily experience for users who frequently pause and resume work sessions. The efficient low-load design also contributes to cooler, quieter performance during idle periods. No additional software or accessories are bundled beyond the standard power cables required for installation.

Perguntas sobre este artigo

What ATX standard does the 420W unit meet for Modern Standby wake times?

The supply is Modern Standby compatible, enabling extremely fast wake-from-sleep transitions and improved low-load efficiency.

What case clearance and mounting pattern does the GIN-3420V require?

It follows the standard ATX form factor, so it fits any chassis with an ATX PSU bay and four rear mounting screws.

How do I install the PSU and which step do builders often miss?

Mount the unit with four screws, connect the 24-pin motherboard and CPU power cables, then verify the Zero RPM fan mode engages at low load — many forget to enable Modern Standby in BIOS.
