KHACHIMO S12-600P2A 600W Gold ATX PSU

This KHACHIMO S12-600P2A is a 600W ATX power supply certified to 80 PLUS Gold efficiency. It suits PC builders and upgraders who want high-efficiency power delivery for a modern desktop build. The unit supports Modern Standby for extremely fast wake-from-sleep times and improved low-load efficiency. It provides reliable power for standard system configurations.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine for quieter operation. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. This design enables the use of more energy-efficient sleep states while maintaining stable voltage output. Build quality focuses on efficiency and acoustic performance.

Check ATX fit and Modern Standby support

Before ordering, verify your case accepts a standard ATX power supply and that your motherboard supports Modern Standby to use the fast wake features. Ensure the unit's connectors match your components' requirements for the 12V rail and other power needs. Confirm the 600W capacity meets your system's total power draw. The Gold certification helps lower power consumption and operating temperatures.

Questions about this item

Does the 80 PLUS Gold rating cap the 600W output in any way?

The 80 PLUS Gold certification measures efficiency at typical loads, not maximum output. The unit is rated to deliver 600W continuously while meeting those efficiency targets.

What physical clearance does this ATX power supply require inside the case?

It follows the standard ATX form factor, so it fits any chassis with a dedicated ATX PSU bay and the usual four mounting screws on the rear panel.

Which cables must be connected first to enable Modern Standby and Zero RPM mode?

Attach the 24-pin ATX and 12V CPU connectors before powering on; the firmware uses those rails to manage sleep states and fan-stop thresholds.
