From a functional standpoint, the units are 80PLUS Bronze certified, which is to be considered near the lower range of power efficiency these days, as many other offerings do come in Silver and Gold certification. But both units did well, running quiet at idle and load for the most part, the cable lengths are sufficiently long which is notable for those who have full tower cases and are very particular about their cable management.
