80 PLUS Titanium specification for ultra high efficiency
The AX1500i, simply put, approaches near-perfect efficiency like no other desktop PC power supply has ever done. Amazing efficiency has so many benefits – not only does it lower your operating costs, but it generates less heat, too. And that means that there’s less cooling required, which lowers noise.
Zero RPM Fan Mode for silent operation at low and medium loads
In fact, most of the time, no active cooling is required. The fan simply doesn’t spin. And when you’re pushing it hard, the thermally controlled fan adjusts its speed to match demand. The custom-designed fan is extra large, with a diameter of 140mm for low noise even at full load, and it uses a fluid dynamic bearing for quiet, reliable operation.
