450W ATX Power Supply

This 450W ATX unit carries 80 PLUS Gold certification and uses resonant LLC topology with DC-to-DC conversion for stable voltage delivery. Modern Standby compatibility enables rapid wake-from-sleep and improved low-load efficiency. A zero-RPM fan mode stops the fan entirely at light and medium loads for silent running.

Ideal for mainstream desktop builds

Suits builders assembling office workstations, home PCs or entry-level gaming rigs that stay within a 450W power budget. The Gold-rated efficiency and quiet fan profile also benefit noise-sensitive environments. Systems requiring higher sustained output, multi-GPU configurations or fully modular cabling should consider higher-wattage alternatives.

Gold efficiency and Modern Standby support

The 80 PLUS Gold rating ensures lower energy loss, reduced heat and quieter operation compared with Bronze units. Modern Standby readiness allows the platform to enter and exit ultra-low-power sleep states without compatibility issues. These two factors together determine whether the unit matches the platform's efficiency and sleep-state requirements.
