When I got this cable kit it worked well when installing a USB-C hub and gave it the extra power it needed to make devices work better, like my Logitech Streamcam with a higher frame rate. I really like the design as it is a durable cable that will not cause any problems for the first few weeks of use. We highly recommend purchasing this cable set if you need to upgrade your desktop PC from SATA to Molex power. Worth buying.
