Totally feel you on this one. I have been very disappointed in many of the higher end power cables from Shunyata, Wireworld, and Synergistic. They do not trip well at all. In many cases I have had to place an object or 2 under the connection to the component so they stay in place and connected.
I highly recommend DH Labs. Specifically the Power Plus Cryo and Red Wave. These cables have a super tight and secure grip. The best I have experienced. Plus they’re amazing cables. I replaced a Shunyata Delta on my Processor with the Power Plus and what a difference! Solid connections!
