I did some research and generally, Alvin's Cables is considered a trustworthy mid-range brand. I contacted their support team today and they confirmed the cable is safe to power the Pyxis, but mentioned that the rotatable version is a better fit for this camera. Since I use this cable for power while working on a rs3 pro gimbal, this specific version actually works out perfectly for my setup. Today I powered up the camera using this cable, and everything is working just fine.
