When it comes to power supplies we know that the 80 PLUS certifications are very important. The certification lets consumers know how efficient the power supply they are purchasing is. Currently the highest certification in the US is 80 PLUS Platinum, which offers 92% efficiency at 50% load and 89% efficiency at 100% load. Today we will be taking a look at one such 80 PLUS Platinum certified power supply in Rosewill’s Tachyon 750W unit. This power supply features a single 12V rail design, semi-modular cables, and a silent 140mm fan. Let’s take a look!
