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.

Questions about this item

What motherboard power connector does this 450W ATX PSU require?

It uses the standard ATX 24-pin main connector and matching 4/8-pin CPU power connector found on modern motherboards.

Will the Zero RPM fan mode stay off when my system enters Modern Standby sleep?

Yes, the fan remains stopped at low and medium loads, and Modern Standby compatibility keeps efficiency high during sleep.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Monitor power draw at the wall under typical load; the unit should draw noticeably less AC power than a non-Gold supply for the same DC output.
