Given the amount modern GPU's are requiring that doesn't seem such a rare occurrence. During some game sessions, my 3080 will max out the capacity of my consumer UPS and ponder if a loose pin on the power connectors could cause a spark enough to jump the connectors. I guess my only saving fate is I let my computer sleep when not in use.

It's not a spark, it's a loose connection. This causes higher resistance, which generates heat, which melts the insulation and then makes it worse. Even though it's only 12V, there's enough amps flowing to cause plenty of issues.
