I'm curious about something strange I noticed with my GPU. I recently slotted a 5080 into the PCIe slot, and it unexpectedly powered on my PC, even without the 12v-2x6 connector plugged into the GPU. I tried the GPU in another system, and it did the same thing. So, I'm wondering if this could be due to a feature of the GPU or if it might be faulty. Also, I've started turning off the power supply every time I work on my PC, but I'm just trying to understand why this happens in the first place.

Honestly, you’ve been pretty lucky! It's essential to turn off the PSU whenever you're doing any work inside your machine. It's really easy to cause damage with just a small mistake. Just remember to unplug the PSU and drain any remaining power by holding the power button before you begin tinkering.
Just a heads-up, always make sure to turn off the power supply before you start messing around inside your PC. The motherboard can still receive power even if the PC is "off". Keeping everything safe should be a priority.
It sounds like your GPU might be triggering a Wake on LAN type of feature on the PCIe lanes. It's crucial to remember that you should always turn off the power when working with components that aren't designed to be hot-swapped!
