KHACHIMO 1000W Switching ATX Power Supply FSP500-80AGGBM(M) 80 PLUS Gold

1000W ATX Gold power supply for efficient builds

This 1000W ATX power supply carries 80 PLUS Gold certification for high-efficiency operation. It targets system builders who want lower power draw, reduced heat and quieter performance in a standard form factor. The unit uses resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power across all rails. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Zero RPM fan mode and resonant LLC topology

The bundled Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion reduces coil whine and supports more energy-efficient sleep states. These features change the acoustic profile and power quality without adding extra cables or software. The design focuses on hardware-level noise reduction and stability rather than bundled accessories.

Practical limits of ATX 80 PLUS Gold standard

The ATX form factor and 80 PLUS Gold rating set baseline efficiency and physical compatibility but do not guarantee specific cable lengths, connector counts or transient response figures. Builders needing specialised connectors or extreme overclocking headroom should verify the exact pinout and protection circuitry against their component list. The standard does not define maximum combined rail outputs or hold-up time beyond minimum certification requirements.
