Helpful Advice Please :)
I currently have:

Case: https://rog.asus.com/us/desktops/mid-tower/rog-strix-gl12-series/

Dimensions of case: (H x W x D ) 7.0 x 15.7 x 18.0 inch

Power supply: Will upgrade to ASUS ROG THOR 1200W

Chipset: Intel Z390

Current Graphics Card: NVIDIA GeForce RTX 2080 8gb

I am hoping for any help in what I need to buy besides upgrading power supply and if the NVIDIA Geforce RTX 3090 Founders Edition will fit my case?

1200W is mega overkill, even TITAN RTX only needs 650W; pretty sure 3090 is the same, so 850-1000 would be better.

Would it hurt anything to have overkill?

the efficiency the discrepancy is too large. at most you should go for 1000 with your setup if you're not NVlinking

Thank you for the clarification.
Now, do you think my build and case can handle the GPU I am interested in? Minus the power supply of course.

i find people typically use 360mm cases for the airflow with higher end cards like 3090.

NVIDIA recommends a 750W power supply for the RTX 3090. It's best to stick to that specification as to not leave it off the table.
The 1200w wouldn't be a bad choice as it will keep around 50% load, which is both efficient, cool and quiet gir the psu.

If you choose to watercool or mod in the future the cards have a bunch of extra performance to give and can pull 700w ish.

Regarding the card fitting, it's a wide boy abd may not close with the side on, the case also seems pretty restrictive surflow wise, could potentially fix the issue with a vertical mount kit, but, may be best to look for a new case, as you are looking at £1400 cards, I can assume you can afford a new case also :)

I appreciate the information on the Power Supply, as I want the 1200 watt anyhow. I however really dont wanna invest in another case as this one is only a year and half old and I love it lol. The size is mid range and I am unsure about the GPU specs as far as dimension are concerned.
I have read a lot of conflicting articles stating if I have a RTX 2080 I should be fine. As well as some stating it can fit in a mid range but it'll be snug. I'm just not very good with... well dimensions :P

I am wondering what my dimensions are for what card needs... if that makes sense.
3090 founders edition is 313 mm (12.3 inches)

2080 founders edition is 267mm (10.5 inches)

The length won't be an isdue, the width will be, it's 138mm/5.4 inches wide, on top of that you have the power cable sticking out a good 25mm/ 1 inch further.

It's basically the size of the large custom 2080ti models which were notably larger than more basic 2080 models.

Given that my old 2080ti ftw3 had the cables squashed against the glass in a lian li 011 dynamique and looking at pictures of your case, it doesn't appear to have as much space, which is where vertical mounting could help, but, depending on how the slots on the back are done, may require some modding with a dremmel

On the back I have four slots. Ill have to measure it to see what 5.4 inches would look like. As far as the power cord....umm

Well the cases total dimensions look to be 7 inches wide, it's unlikely you'll fit a card thst with power cables in, is going to be a good 6 1/2 inches wide in it given the motherboard / standoffs and space behind the motherboard tray is likely to be more than half an inch, best bet is to go measure how much space you have now, or how wide your existing card is, or, go Google its dimensions, failing that, tell us its model so we can Google it for you....
I just double checked the pic, yeah no vertical mounting for you, you need 6 or 7 slots, atleast, I don't think it will fit, as I said, I think you need a bigger and better designed case I'm afraid.
