The last few months have seen an increasing number of 80PLUS Gold certified power supplies passing through my hands. Each have their own unique way of incorporating abundant amounts of the colour gold into their packaging and chassis designs. Today I have one of the highest end 80PLUS Gold power supplies I have handled recently on my bench - the OCZ ZX 850W. The ZX series is OCZ's highest range of performance power supplies - built with quality, performance and efficiency in mind. It's time to see if the extra investment in this high end power supply will be worth the money over the more budget minded 80PLUS Gold models that have crossed my bench prior to this model.
