450W ATX Power Supply for Modern Standby PCs

This KHACHIMO 450W ATX unit delivers 80 PLUS Gold efficiency for lower running costs and cooler operation. It supports Modern Standby for extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. The unit is new and ready for installation.

Ideal for quiet office

Builders who want near-silent operation at low and medium loads benefit from the Zero RPM fan mode that stops the fan entirely. Systems relying on Modern Standby for instant wake and deeper sleep states are well suited. It is not for systems requiring higher wattage output than 450W. Buyers needing modular cabling or specific connector counts not detailed here should verify compatibility separately.

80 PLUS Gold efficiency rating defines

The 80 PLUS Gold certification confirms high efficiency operation across typical loads, reducing power consumption, noise, and heat. This rating is the primary specification for judging whether the unit meets your efficiency and thermal targets. No other efficiency standard is claimed for this model.
