I'm having an issue with my ROG STRIX 3080 where it won't draw more than 100 watts. The card isn't throttling, and the temperatures are normal. I've tried using the BIOS switch, but that hasn't resolved the problem. I've noticed in HWInfo that the core voltage sometimes drops to 0 for a brief moment. The power cables are secured properly, and there's no sag with my setup. I'm using an 850-watt PSU.

It sounds like your PSU might be overheating and unable to deliver enough power. This is a pretty common issue, especially in cases where there's excessive dust buildup or if the PSU isn't ventilating properly. You might want to check your PSU vents to ensure they’re clear.
Make sure that your power supply connections are secure. Even if they look tight, sometimes reseating them can help. And if you’re using a modular PSU, check the cables to see if they’re fully connected. If that doesn't solve it, the PSU might need to be tested.
