Most of the time we focus on enthusiast and gaming power supplies here at TweakTown. Occasionally, when a product warrants it, we will cover other power supplies as well. The unit we are taking a look at from Super Flower today is one of those units that warrants taking a good look at. It is the Super Flower Golden King SF-550P14PE 550W power supply. After taking a look at the Super Flower Golden Green 800W PSU last month, we were quite interested in seeing what else they had to offer, so we had them send one over. At this point you're probably wondering just what is so special about a 550W power supply. Well, ladies and gentlemen, this is one of the first 80Plus Platinum power supplies to come to market. You heard that right, Platinum efficiency. Up until now, the 80Plus Platinum logo has just been a myth that nobody has really seen it. For those unfamiliar with the certification, 80Plus Platinum certification requires that the power supply be able to achieve 90%, 92%, and 89% efficiency at 20%, 50%, and 100% loads respectively. At the time of writing this article, there are only 18 power supplies listed with Platinum certification on the 80Plus.org website. Super Flower has designed six of these. Let's check this thing out and see what Platinum is all about.
