Modern Standby ATX Supply

The KHACHIMO PDC1000S12-DB is a 1000W ATX power supply built for systems that use Modern Standby sleep states. Its 80 PLUS Gold certification means high efficiency across typical loads, reducing waste heat and fan noise. The resonant LLC topology with DC-to-DC conversion delivers clean, stable power to sensitive components. It suits high-performance desktops and workstations that prioritise low-load efficiency and quiet operation.

Compatibility Checklist

Verify that your case accepts a standard ATX form-factor unit and that the cable harness reaches your motherboard, CPU and GPU connectors. Ensure the total system draw stays within the 1000W rating and that the 12V rail can handle your graphics card’s peak demand. Confirm the mainboard supports Modern Standby if you want the fast wake behaviour advertised. Builds needing redundant or server-grade features should look elsewhere.

Bundle Impact

The unit ships with the standard modular cable set required for typical ATX builds, including motherboard, CPU and PCIe leads. No extra adapters, mounting brackets or monitoring software are included in the package. The Zero RPM fan mode works automatically without any driver installation. All efficiency and noise benefits come from the hardware design itself, not from bundled utilities.
