At about 12:33, it looks like they’re plugging expansion cards into a motherboard that still has power, as there’s what appears to be an LED on on the motherboard. It’s possible that this motherboard doesn’t power the PCI slots in that state, but man, I would not be plugging any expansion cards into a motherboard without the PSU powered off.
It has been quite a while so I’m fuzzy on it, but I had a board with a status LED and it would stay on for a bit as the capacitors drained? Generally a good thing to watch when you wanted to properly pull power from it for whatever reason though, especially with how often I was thoroughly crashing it and then resetting things with my overclocks. :P
and it would stay on for a bit as the capacitors drained?
Yeah, I’ve had that too, but I don’t think that that’s likely what’s going on there, if they fully shut the thing down, flipped the PSU switch off, and then started filming the card being inserted. LIke, it was maybe a couple of seconds at most. And honestly, I’d probably still want to avoid plugging stuff into a board while that is on, since I don’t know what other stuff also might be powered up on the motherboard. :-/
I guess anything is possible, but I don’t think I’ve ever seen a CMOS battery light, though I’ve seen a lot of motherboards with an LED to indicate that they’re getting power from the PSU. I’m pretty sure that you’d burn through a CMOS battery pretty quickly if you just left an LED always on powered off it.

I once dropped a screw into a running PC and it shorted. Sparks and all. I just turned it back on again and it was fine.
Perhaps the LED stays on without PSU power (CMOS battery status LED)?
This is a relatively big channel. It’s unlikely they they would make such a mistake.

I’ve also never seen a CMOS battery LED, that was a random though.
I just don’t the idea of them messing around the with PC with the PSU on a bit shocking.
