The Cougar MX330-G has a blocky USB 3.0 cable connector. Not a problem with most motherboards. Unfortunately, the MSI Tomahawk X570 motherboard has a right-angle USB 3.0 connector. Plugging that blocky connector into a right-angle connector made for a tight spot. I picked up a 6″ USB 3.0 motherboard extension cable to remove that tight spot.
