Today we take a look a power supply from be quiet! – from their new Straight Power 11 range. They claim this is their quietest power supply range yet and we have the 850W model up for test today. These new power supplies are now Platinum certified and have received some other tweaks to modernise them for 2020.
The main talking point will obviously be the move from Gold efficiency rating to Platinum efficiency. be quiet! say they have optimised the layout, moved from a half bridge to full bridge topology and replaced some of the internal components. This Full Bridge + LLC + SR + DC-to-DC topology helps achieve the highest possible efficiency. This new range of power supplies are equipped with up to six daughter cards providing Full Bridge conversion, DC to DC transformation, LLC and Synchronous rectification.
The new range of Straight Power 11 are available at up to 1200 watts, giving a 200 watt boost over the previous Gold efficiency generation. The 650W model in the range now ships with a second P8 connector which will help deliver higher levels of power to more demanding processors on the market today. Surprisingly, there is only a 5 year warranty with these models which seems rather short compared to brands such as Seasonic (who offer 12 year warranty on their Platinum models).
