My asrock x470 provides sufficient power over USB-C to keep this 100% charged 24/7. But now thats not the issue. The real issue is the EOS Beta webcam software only sends 1024x576 resolution, and the picture looks terrible. I hooked my G7X M3 to a USB capture stick, and I'm sending clean HDMI video at 1920x1080 to my OBS now, and its beautiful. And this way, my charging port is freed up for straight charging via a PD block or via my USB-C on PC if I want. Both work fine. I cant recommend the EOS Beta webcam utility until it at least outputs 1920x1080 resolution.
