No facility for Spoiler tags here, so you get a Cut&Paste of my Spec reminder text, though I've deleted most of the original 2013 components, some
Case, Sound Card, and 2 SSDs remain from that build.

Even so I suspect my issues are Motherboard, or RGB related, from purchase, but only really noticed by me since Nov 2021.

I've used a Master Plug controlled extension based Turn off system ever since I first got this PC if not longer, it worked great.
I'd switch off my PC in Windows, and all Peripherals attached to that surge protected extension, switched off within a second of the PC shutting down.
My old EVGA GTX 1080 FTW2, had no RGB crap, I wanted, and I never noticed this issue, but suspect now it's existed since I bought the Mobo:
Purchase Date: 2018/10/04

Since I upgraded my GPU to the EVGA RTX 3080Ti FTW3, and started using the only useful RGB feature, Temperature indication, I've noticed the problem.
My PC doesn't shut Down via Windows, or front Case switch at all, Windows shuts down just fine, but PC remains on, and thus All peripherals are fully on or in Standby mode, wasting my expensive electricity.

OK, turn off at rear of PC, and while it works it's only after 10 seconds or so that the RGB stops drawing power, by draining Capacitors I assume.
This is way to slow to trigger the Master Plug though, and the monitors (Main culprits with old Dells having power hungry standby) are why I got the plug.
The Master Plug turns the monitors, and other peripherals with separate power supplies on/off with my PC.
So the system in practice has acted as zero power use standby controlled by windows shut down, it's ideal, or was.

So I need a solution, and I'm not convinced the RGB is actually the problem, since last night I remembered to turn off the back Power button on the case, to no effect. I'd like to keep the RGB on for Temp indication, but can live without it, if the 10 second shutdown goes away with it.
Not actually tried doing that yet, as it's a last resort solution, and if capacitors must be drained before mobo shuts down, why would RGB off even change that.

Hence making this post to see if anybody else uses such Master Plug extensions, mine was one of the first models available, as I'm a great believer in if it still works, it's worth keeping, but maybe newer ones can even cope with this no/slow power off issue.
