300W ATX Power Supply for Modern Standby Systems

This 300-watt ATX unit is built for PCs that use Modern Standby sleep states. It suits office desktops, compact workstations and low-power builds where fast wake times and efficient idle behaviour matter more than high-output rails.

Sustained Load Behaviour

The 80 PLUS Gold rating means the unit maintains high efficiency across typical workloads rather than only at peak. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight during continuous operation, reducing ripple and avoiding the voltage sag that can appear on simpler designs after minutes of load.

Thermals, Noise and Power Draw

Zero RPM fan mode stops the fan completely at low and medium loads, giving near-silent running for everyday tasks. Gold-level efficiency lowers waste heat, so the power supply runs cooler and draws less from the wall during normal use, while the resonant design also cuts coil whine for a quieter overall system.

Questions about this item

How loud is the 300W power supply when it runs all day under typical load?

The Zero RPM fan mode stops the fan completely at low and medium loads, while 80 PLUS Gold efficiency and resonant LLC topology reduce heat and coil whine for quieter operation.

Which cables or connectors must my system already have to install this ATX unit?

The unit follows the standard ATX form factor, so your case and motherboard must provide the matching ATX power connectors for the 300W supply to function.

Will the Modern Standby feature work with an older motherboard that lacks Modern Standby support?

Modern Standby compatibility enables fast wake times on supported platforms; on older hardware without that support the supply still delivers clean 300W power but the fast sleep-state benefits will not activate.
