*This is the real Add2PSU adapter, not a knock-off of unknown quality. We are an authorized seller of this patented product, a product which is currently in use by thousands of computer enthusiasts and cryptocurrency miners. Many sellers on here are now copying the text from our listing to sell their counterfeit products. Often, the differences can be spotted, such as when the PCB isn't exactly the same as an authentic Add2PSU or when they have a different backing than the white 3M brand adhesive pad that is on an authentic Add2PSU adapter.*
