In Win sent us their newest model GreenMe rated at 650W. Billed as an eco-friendly alternative to the common PSUs, In Win boasts about the reduced energy costs associated with the high efficiency design. Given the eco emphasis, we'll examine how the PSU does in those areas along with the usual tests. Is this green power supply a good option for the environmentally conscious users? Read on to find out! The GreenME like any decent modern power supply also carries an 80 Plus certification, this time for the Bronze level. That means the PSU should run at 82% efficiency with a load of 20%, reaching 85% efficiency or more at a load of 50%, and still maintain 82% efficiency at the maximum 650W rated load.
