Power supply for MEGMEET 4.2V systems

This ATX unit delivers 300W at 4.2V and is built for modern standby compatibility. It suits builders who need fast wake-from-sleep behaviour and high efficiency at low loads. The 80 PLUS Gold certification confirms reduced power draw, cooler running and quieter performance.

Fits standard ATX layouts

Resonant LLC topology with DC-to-DC conversion provides clean power and enables deeper sleep states. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. Buyers who need higher wattage or a different output voltage will need another model.

Replaces older MEGMEET 4.2V units lacking modern

The jump is worthwhile when faster sleep recovery, lower idle consumption and quieter operation matter. It does not suit systems that require more than 300W or a voltage rail other than 4.2V.

Questions about this item

What continuous load can the 300W ATX unit sustain without overheating?

The 300W rating is the maximum continuous output the supply is designed to deliver within its thermal limits.

How loud and hot does the power supply get during all-day operation?

At low and medium loads the Zero RPM mode stops the fan completely for silent running; 80 PLUS Gold efficiency reduces waste heat, keeping temperatures lower under sustained use.

What motherboard connector does this 4.2V unit require to function?

It uses a standard ATX form factor and connects via the regular 24-pin motherboard power socket.
