KHACHIMO 450W ATX Power Supply 80 PLUS Gold

450W ATX Gold PSU

This KHACHIMO unit is a 450 watt ATX power supply with 80 PLUS Gold certification. It targets desktop builders who want high efficiency and quiet operation in a standard form factor. Modern Standby support allows extremely fast wake-from-sleep times and better low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine.

Ideal for efficient quiet builds

Suits users building or upgrading a mainstream PC where 450 watts covers the component list and silent running is valued. The zero RPM fan mode stops the fan at low and medium loads for near-silent operation. Builders needing more than 450 watts for high-end graphics cards or multi-GPU configurations should look at higher-capacity units. Systems requiring proprietary form factors such as SFX or TFX cannot use this ATX model.

Verify ATX fit and connectors

Confirm the case accepts a standard ATX power supply and that the motherboard uses a 24-pin main connector plus the required CPU power connector. Check that the graphics card power needs match the available 6-pin PCIe connectors on this unit. Ensure the total system power draw stays within the 450 watt rating. Modern Standby features require a compatible motherboard and operating system.
