POWER SUPPLIES / PSU

You’ve probably seen different badges on different power supplies (psu). They usually have labels like 80+ with some sort of naming afterward for certification. The most common power supplies are 80+, 80+ bronze, silver, gold and the best 80+ Platinum and Titanium. 80+ PSUs provide 80% efficiency at a given load. Another thing to note is that the 80+ PSUs also have further brandings such as the 80+ bronze, silver, gold, platinum, and titanium. The difference between them is that some have higher efficiency at 20%, 50% and 100% load.
