USB Risers can confuse people sometimes. So here is a quick review of what you can buy and how they will help you with your GPU mining. You shouldn’t buy anything below v.5, although that doesn’t mean they won’t work – It just means you aren’t getting the latest products. For Molex connections, you should buy Ver.5c. Then we have Ver.6c, which enables you to connect a 6 pin connector. And finally, the Ver7.s enables you to connect a SATA wire directly into the riser, without the use of the sketchy molex/SATA adapter. Remember never to overload your cables – You won’t have this problem with the 6 pin usually, but for SATA its better to have just one or two max on a single cable, and same for Molex. In case of doubt, use less, and always check cables for heat while running. If they are hot to the touch, then your setup needs to change. Below are some sponsored links to each version that you can buy on Amazon.
