Unfortunately, generic mounts often fail. I had issues with sag which was honestly not as good as expected.

• Use reinforced steel.
• Buy Cooler Master Universal Vertical GPU Holder Kit V3 PCIe 4.0.

^ This. Also, I'm totally obsessed with the CableMod Vertical PCI-e Bracket 4.0 Edition! It's absolutely fantastic because it sits inside the chassis so you dont have to cut those 5000D bridge bars.

• high-gauge steel to stop torque
• zero signal loss on pcie 4.0
• better airflow gap from the glass Honestly, the 4080 is a total tank but this bracket handles it like a dream! Youll love how it stays silent.

Re: Honestly its such a shame that manufacturers still...

• yeah, it's a joke. I've dealt with this for years. If you want something that actually stays put without spending a fortune, look into the Phanteks Universal Vertical GPU Bracket. It's built like a tank and keeps heavy cards from leaning at all. I've used this with a few different builds and it never budges. It gives you way more clearance from the glass than those cheap ones too, so your fans can actually breathe. If you're in a rush, check if you can snag the Fractal Design Flex B-20 Vertical Riser Bracket locally. It's super sturdy and designed specifically to handle the weight of bigger cards like your 4080. TL;DR: Stop buying the cheap aluminum stuff. Go with a solid steel bracket like the Phanteks or the Fractal one. They cost a bit more but they wont destroy your fans or your sanity.

Unfortunately, generic mounts often compromise safety. Does your 5000D have those divider bars between expansion slots? I'd recommend searching for a discounted Lian Li VG4-4-V2 Vertical GPU Kit for around 60 quid.

Honestly its such a shame that manufacturers still pump out these flimsy brackets when modern cards weigh as much as a small brick. I have seen way too many setups ruined because people underestimate the sheer torque a heavy card puts on the mounting points. Unfortunately, I had issues with several supposedly premium kits in the past that just werent as good as expected once you actually put a real card like your 4080 in them. One thing you really need to be careful about with that Corsair 5000D is the actual thickness of the metal on the bracket itself. If it feels thin, it probably is. You want something that basically locks the card in place so there is zero wiggle room. Also, watch out for those cheap riser cables. I have had cases where the signal dropped out randomly because the cable couldnt handle the bandwidth, which is a nightmare when you are trying to stream. Just make sure whatever you grab is rated for PCIe 4.0 or you will be pulling your hair out over stutters and crashes mid-stream. Keep an eye on those bottom fans too, if you have no clearance the temps will spike fast. Its a lot of weight to hang off a few screws so dont settle for anything that feels light.
