300W ATX power supply

This 300W ATX power supply delivers reliable power for compact office PCs and basic home builds. Its gold-rated efficiency helps lower running costs and reduces heat inside the case. The unit suits users who value quiet operation and modern sleep states over high-wattage headroom.

Practical limits of 300W ATX

A 300W rating restricts the unit to systems with integrated graphics or low-power discrete cards. High-end CPUs and multi-GPU configurations will exceed the available power budget. Builders planning future upgrades should verify total system draw before choosing this model.

Build quality and daily implications

Resonant LLC topology with DC-to-DC conversion supplies stable voltages and minimises coil whine. The Zero RPM fan mode stops the fan completely at low and medium loads for silent running. Modern Standby compatibility enables near-instant wake times for a responsive desktop experience.

Questions sur cet article

Should I choose the 300W or 500W version of this power supply?

The product is supplied as a 300W unit; the 500W figure appears in the model name but does not represent a separate capacity option.

What does the 80 PLUS Gold rating mean for my system?

It guarantees at least 80 per cent efficiency at typical loads, reducing electricity draw, heat output and fan noise.

Does the ATX form factor limit the connectors I can use?

The ATX design follows the standard layout, so it fits regular cases and provides the usual motherboard, CPU and peripheral connectors.
