  • 1500 W ATX output handles demanding multi-GPU and workstation builds

1500W ATX Power Supply for Demanding Builds

This 1500W ATX unit targets high-performance desktop builders who need substantial continuous power for multi-GPU configurations or heavily overclocked components. It delivers the headroom required for sustained heavy workloads without relying on peak ratings. Systems with modest component counts or strict budget constraints will not utilise its full capacity.

80 PLUS Gold and Modern Standby Features

Gold-rated efficiency reduces waste heat and lowers operating costs during typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean power and reduces coil whine.

Capacity and Headroom for Heavy Loads

The 1500W rating comfortably handles multi-graphics-card arrays, high-core-count processors and numerous storage devices simultaneously. Efficiency remains strong across a wide load range thanks to the 80 PLUS Gold certification. Builds requiring significantly more than 1500W of continuous DC power will exceed this unit's capability.

Highlights

  • Modern Standby gives near-instant wake and better idle efficiency
  • 80 PLUS Gold certification cuts power draw, noise and heat
  • Zero RPM fan mode stops the fan at low and medium loads for silent running
  • Resonant LLC topology with DC-to-DC conversion delivers clean, stable power and reduces coil whine
  • 1500 W ATX output handles demanding multi-GPU and workstation builds

Questions about this item

How often will the fan bearing need replacement if the Zero RPM mode keeps it off at low loads?

The fan only spins above medium load, so bearing wear is minimal and no scheduled replacement interval applies.

Which protection trips first when the 1500W unit runs at full load continuously?

Over-temperature protection activates before the 80 PLUS Gold efficiency curve drops off.

Does the 48 V DC-to-DC rail add audible coil whine or extra heat during all-day operation?

Resonant LLC topology with DC-to-DC conversion reduces coil whine and keeps temperatures low even under sustained load.
