ATX PSU for Modern Standby builds

This 300 W ATX power supply carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep. It targets system integrators and DIY builders who need efficient, low-noise power for compact or mainstream desktops.

300 W continuous output

The unit delivers 300 W of continuous power through a single 6-pin connector, making it suitable for platforms that draw within this envelope. Builds requiring higher wattage or additional PCIe connectors should select a larger capacity model.

Gold efficiency with Zero RPM mode

At low and medium loads the fan stops completely, eliminating audible noise while 80 PLUS Gold efficiency keeps temperatures down. The resonant LLC topology with DC-to-DC conversion further reduces coil whine and supports deeper sleep states.

Questions about this item

What does the 300 W rating mean for a typical desktop build?

It provides up to 300 W of continuous power for the motherboard, CPU, graphics card and drives, so the total system draw should stay below that figure.

What does the 80 PLUS Gold badge tell me about efficiency?

The unit meets the Gold efficiency targets set by the 80 PLUS programme, meaning less energy is wasted as heat and the fan can run slower or stay off longer.

Will this ATX power supply fit a standard mid-tower case?

It uses the ATX form factor, which matches the mounting holes and dimensions used by most mid-tower and full-tower chassis.
