KHACHIMO 450W ATX Power Supply DPS-450DB K

450W ATX power supply for modern standby systems

This 450W ATX unit delivers reliable power for desktop builds that rely on fast wake-from-sleep behaviour. It targets users who want an efficient, quiet supply without excess wattage headroom. The 80 PLUS Gold certification confirms high efficiency across typical loads. It suits office workstations and home PCs that spend long periods in low-power states.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC design combined with DC-to-DC conversion produces clean, consistent voltage rails and reduces coil whine. Standard ATX connectors fit mainstream motherboards and peripherals without adapters. The topology also enables deeper, more energy-efficient sleep states supported by modern operating systems. Builders who need non-standard EPS or high-current PCIe cables should verify compatibility before ordering.

Zero RPM fan mode and gold-rated thermals

At low and medium loads the cooling fan stops completely, providing near-silent operation during everyday tasks. The 80 PLUS Gold rating means less waste heat, which keeps internal case temperatures lower and reduces the need for aggressive fan curves. Under heavier sustained loads the fan engages to maintain safe component temperatures. Users seeking completely fanless designs or supplies rated for continuous maximum output in hot enclosures will need a different class of unit.
