ATX power supply with 14-pin connector

This 500 W ATX unit uses a 14-pin main connector and is built for systems that require this specific pin layout. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep. The resonant LLC topology with DC-to-DC conversion delivers stable output and helps reduce coil whine. It suits builders replacing an FSP500-50ETN, FSP500-50AGPA, FSP450-50ETN or HK380-16FP unit.

Practical limits of the 14-pin interface

The 14-pin main connector is not interchangeable with the standard 24-pin ATX header found on most current motherboards. Using this unit requires a motherboard designed for the 14-pin layout or a verified adapter that matches the pin-out exactly. The 500 W rating sets the total power ceiling for all rails combined. Zero RPM fan mode operates only at low and medium loads, so the fan will spin under heavier demand.

Installation notes and common issues

Installation is straightforward when the motherboard natively accepts the 14-pin connector; simply seat the plug firmly and secure the unit with four screws. Builders often discover the connector mismatch only after opening the case, so verify the board header before purchasing. Cable routing space varies by chassis, and the fixed cable set cannot be reduced. Coil whine is minimised by the topology, but a small number of units may still exhibit faint noise under specific loads.

Questions about this item

Should I choose the FSP500-50ETN, FSP500-50AGPA, FSP450-50ETN or HK380-16FP model?

The FSP500-50ETN and FSP500-50AGPA are 500W units, the FSP450-50ETN is 450W, and the HK380-16FP is 380W; pick the wattage that matches or exceeds your system's peak power draw.

What does the 500W rating mean once installed in my PC?

It means the unit can continuously deliver up to 500 watts to your components combined; your actual draw depends on the CPU, GPU and other parts you have installed.

Is the 14-pin connector a standard ATX interface and what limits does it impose?

The PSU uses an ATX form factor with a 14-pin main connector designed for specific proprietary boards; it will only power motherboards that accept that exact pin-out.
