What are the best support brackets to prevent GPU sagging?

Question

What are the best support brackets or kickstands or whatever to stop my graphics card from drooping because I'm terrified it's actually going to snap off the motherboard? I just finished putting together my very first gaming PC and it cost me way more than I should have spent—about $2,600—and the graphics card is this huge RTX 4080 thing that looks like a literal brick. I noticed this morning that the end of the card that isnt screwed into the back of the case is hanging down a lot lower than the other side and it just looks like its under so much stress. I cant stop thinking about those tiny little gold pins inside the slot just snapping or bending and then I'm out two grand.

I'm sorry if this is a really basic question but I honestly have no idea what I'm looking for or what the different types are. I saw some people online using literal Lego bricks or stacks of pennies but that feels like a bad idea for such an expensive machine? I live in a small place in Philly and the subways go right under my building so the whole floor shakes every twenty minutes and I'm scared the shaking is going to make the card bounce and ruin the socket.

I have maybe $25 left in my budget for this month after buying all the parts and I really need to get this fixed by Thursday because I'm starting a new streaming project then. I saw these little screw-up pillars on Amazon and then these long flat metal bars that go underneath.

which one is easier for a total beginner?

do I need to measure the distance from the bottom of the case?

is there a specific brand that is safe?

I really dont want to have to take the whole thing apart again because it took me six hours just to get it to turn on the first time. I'm just really nervous I'm gonna mess up my dream build over something simple...

Unfortunately, those long flat metal brackets are usually a disappointment because they flex too much under a heavy 4080. With your subway vibrations, you need something more rigid than just a thin strip of aluminum.

Measure the exact distance from the PSU shroud to the GPU shroud.

Check out the Cooler Master Universal Graphics Card Holder for better stability. Its a bit more tedious to align, but honestly way safer for a dream build.

I had the exact same issue with my heavy card a while back and went through a few options before settling on a simple vertical pillar. Honestly, I am super satisfied with how it turned out and it completely solved my anxiety about the card bending. Here is what you need to know to get this sorted before Thursday:

Go with the vertical screw-up pillar style. They are way easier for beginners than the horizontal bracket bars. You literally just place it under the corner of the card, twist it to extend the height until it supports the GPU, and lock it. No unscrewing your motherboard or PCIe brackets required.

You should do a quick rough measurement. Just grab a regular ruler and measure from the top of the power supply shroud (or bottom of the case) to the underside of your GPU. Most of these pillars come in different height ranges, like 70mm to 120mm, so you just need to make sure you buy the right size range.

Look for one with a magnetic base. Since your apartment shakes from the subway, a magnet is crucial. It keeps the stand locked to the bottom of your case so it wont slip out when the floor vibrates.

For a budget under $25, I highly recommend the Antec GPU Support Bracket Adjustable Height or the Thermalright TR-GBS Metal GPU Holder. I use the Antec one in my main rig and have zero complaints. It is solid metal, has a strong magnet, and cost me like fifteen bucks. It takes two minutes to install and you wont have to take anything apart.
