At the time of this review the Everest series consists of no less than 11 products, with their power output ranging from a modest 400W all the way up to 1010W. FSP is also the only company who has two products of the same series sharing the exact same power output and base design, but of different electrical efficiency. For example the company also offers an 85Plus (80Plus Bronze) version of all Everest units with an output between 500W and 800W. The Everest 400W is only available as an 80Plus version.
