Compact 300W ATX supply for 2U builds

This 300 watt ATX power supply fits 2U chassis and supports Modern Standby for rapid wake-from-sleep. It carries 80 PLUS Gold certification for high efficiency and lower heat output. The unit is new and ready for integration into compatible systems.

300W continuous output with Gold-class headroom

The 300 watt rating covers typical mid-range components and leaves modest overhead for peak loads. Efficiency stays high across the load range, reducing waste heat and fan activity. Sustained draws above the rated wattage will exceed the design envelope and trigger protection.

Resonant LLC with DC-to-DC and zero-RPM mode

A resonant LLC topology paired with DC-to-DC conversion delivers tight voltage regulation and suppresses coil whine. At low and medium loads the fan stops completely for silent running. This architecture also enables deeper, more efficient sleep states supported by Modern Standby.

Questions about this item

Will the 300W ATX unit fit and power my existing 2U chassis that used the older P2U-6300P model?

Yes, it is a direct replacement with the same 2U form factor and 300W rating for compatible Advantech systems.

How can I confirm the 80 PLUS Gold efficiency and Zero RPM fan mode are active after installation?

The fan stays off at low and medium loads for silent running, and the 80 PLUS Gold rating means high efficiency across typical workloads.

Which cables come attached to the P2U-6320P and what must I source separately?

Fixed ATX 24-pin, CPU 4+4-pin and PCIe 6+2-pin cables are included; any proprietary or extra-length cables are not supplied.
