  • 80 PLUS Gold certification delivers high efficiency, reducing power draw, noise and heat
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent running

For ORION-301-X Systems

This 300 W ATX power supply is built specifically for the ORION-301-X platform. It delivers the exact connector layout and form factor that platform requires. System integrators and owners of that chassis can install it without adapters or cable routing compromises.

300 W 80 PLUS Gold Rating

The unit meets 80 PLUS Gold efficiency targets, reducing waste heat and lowering electricity draw under typical loads. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and minimises coil whine. Modern Standby support enables faster wake times and deeper sleep states.

Zero RPM Fan at Low Load

The cooling fan stops completely during light workloads, keeping the system nearly silent when idle. ATX dimensions allow it to fit the ORION-301-X mounting points directly. Builders gain a quiet, efficient power foundation without modifying the case or sourcing custom cables.

The 300 W rating is the maximum continuous power the supply can deliver to all components combined under normal operating conditions.

How does the ATX form factor limit or define compatibility with cases and motherboards?

ATX dimensions and mounting hole spacing follow the industry standard, so the unit fits any chassis and motherboard designed for ATX power supplies.

What clearance or mounting points does the unit need inside a chassis?

It requires a standard ATX power supply bay with four rear mounting screws and enough depth for the unit’s length, plus ventilation space for the fan.
