480W ATX Power Supply

The KHACHIMO SYS-480-S12 delivers 480W of continuous power through an ATX form factor, making it suitable for mainstream desktop builds and workstations. Its 80 PLUS Gold certification ensures high efficiency across typical loads, reducing electricity costs and heat output. Modern Standby compatibility allows extremely fast wake-from-sleep times and improved low-load efficiency for modern operating systems. This unit targets builders who need reliable, efficient power without enthusiast-grade wattage headroom.

Sustained Load Behaviour

Under sustained load the Resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery and tight voltage regulation. The design supports 12V at 40A and 24V at 20A, providing stable current for demanding components during extended sessions. Energy efficient sleep states are enabled by the topology, allowing the system to meet modern standby requirements without voltage droop. This unit is not for builds requiring multi-GPU configurations or extreme overclocking headroom beyond the rated 480W capacity.

Thermals Noise and Power Draw

The Zero RPM fan mode stops the cooling fan entirely at low and medium loads, delivering near-silent operation during everyday tasks and idle states. 80 PLUS Gold efficiency reduces waste heat, which in turn lowers overall system temperatures and fan runtime. The Resonant LLC design actively reduces coil whine, contributing to quieter operation under electrical load. This unit is not for completely fanless builds that demand zero moving parts under all load conditions.

商品問答

How loud is the fan when the KHACHIMO SYS-480-S12 runs at low and medium loads all day?

The Zero RPM Fan Mode stops the fan completely at low and medium loads, giving near-silent operation.

What cables or connectors must I already have to install this ATX power supply?

Standard ATX motherboard and peripheral cables are required; the unit uses a conventional ATX form factor.

Will the 80 PLUS Gold efficiency work properly with an older motherboard that lacks Modern Standby support?

Yes, the efficiency certification and Resonant LLC topology function independently of Modern Standby compatibility.
