Quiet, efficient operation
80 PLUS Platinum efficiency and Zero RPM Fan Mode mean that at low to medium 
loads, the fan doesn’t spin at all. And when you do push the HXi hard, the 
thermally controlled fan spins only as fast as it needs to.

But that’s not all. It’s quieter than most PSUs when the fan’s not spinning, 
too. The HXi is built with capacitors and other internal components 
specially selected to reduce coil whine and other electronic noise.
