And when you do push the HXi hard, the thermally controlled fan spins only as fast as it needs to. Even when the fan isn't running the HX850i has specially selected components to reduce electronic noise for a near silent PSU.

Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.
Date Issued: 18th Nov 2010
Conceived back in 2004 and brought to market just a year later, the 80 PLUS initiative is one of many standards introduced in an effort to increase energy efficiency in modern technology. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.9 or more at 100 per cent load.
