Today I have a Silverstone ST85ZF up on the desk. This is bound to be something special as I have done a number of Silverstone power supply reviews, and whether the product is from Enhance or Etasis, the review is always ultimately positive. The ST85ZF is Silverstone's 850W flagship power supply, so expectations are high. The top of the box has a number of bullet points. We can put a check on all of these, but need to confirm the last one. The ST75ZF made the same efficiency claim of 80% or better, but I was unable to reproduce this.
