So, any idea what your power usage was during that?

A quick google has a 5800X at 15,500ish so you scored around 79% of that. So in terms of perf/watt you might have had very impressive results.

I do wish there was a site like undervolting-hardware.net which concentrated on these kind of results: "The Undervolter's Guide and Results for current GPUs and CPUs" would be a nice thing to have.

23 amps according to HW monitor.
