My new rig, should I be scared? ... and is there room for a 3080?

Been reading a lot about the Asus / 7800x3d problem with the CPU going POOF!!! Still ordered this system without the GPU as I have an ASUS TUF 3080.

It´s going to be my 1440p rig for the next 4 years, the only concern that have beside the CPU is whether the ASUS 3080 actually fits into the case.

I did write a note about that to the shop, hoping they know how to check that.

This is going to be my first purchase ever of a pre-built rig, couldn´t make it cheaper myself and decided to let them do the work.

Hopefully the 7800X3D doesn`t explode.
And why 3080? 4070 will do the same job with less power and has more VRAM.

Is there any chance you can make a last-minute change to a different motherboard that supports the same processor? I wouldn't be "scared" but knowing what we now do about ASUS and its nefarious ways with BIOS "updates" and shuffling off any warranty responsibilities, yes try to move on and not have that little cloud hanging over.

What is the make and model of the case? If you have measurements of the case, you can look up the exact dimensions of your 3080 and answer that question of whether it'll fit.

Edit: OK I see Vision Viper M130--it looks like a standard case. But wherever you find the dimensions on that page, that's where you can determine whether that 3080 will fit.

It depends on your cabinet whether a GPU will fit inside or not. Any standard size PC ATX cabinet should have enough room for a GPU like RTX 3080.

Also, as said above, 4070 has same performance as 3080 but comes with more VRAM, more power efficient and also cheaper. And there are models like Zotec Twin Edge RTX 4070 which has only 2 fans to fit inside smaller cabinets.

It reads to me like OP already has the RTX 3080. Otherwise, yes, it would make no sense as the RTX 4070 would be a better option.

Update your BIOS and watch your SoC voltage. Do this immediately and frequently. If it's staying around 1.25V (1.3V is fine too but I'd like that buffer), you're definitely fine. If it's around 1.35V like they were before, and spiking higher like it was on some boards (Asus was said to be far worse about this), it is a risk, especially for the X3D chips.

I might even hold off on using Expo (enabling this is what causes the raise in SoC voltage) until I had an updated BIOS that stopped the SoC voltage from going over 1.25V or at least 1.3V. These have been released but I've heard it's a bit all over on how well they're working.

I already have a 3080, don´t intend on switching to 4k anytime soon. It´s fine for 1440p for a good time to come. If Vram ever proves to be a problem I have no quarrels with dialing a few settings down in games.

Well, I would still look into a substitution for that ASUS board. If it's not ASUS being a little crooked right now, it's MSI and its ongoing ransomware issues.

That leaves Gigabyte. Why not ask if they can do that?

I wouldn't have a heart attack over it...but I'd make sure the RAM I use has a EXPO profile that that does not require 1.35V .

Kingston Fury Beast 32GB DDR5-6000 RAM

That RAM has varying EXPO voltages @ 1.25 or 1.35 -- if I were you I would make sure I get the 1.25V one. If they are the same price, no reason not to get the higher binned version.

[The Commendatore]

Without knowing which 3080 you have, that case you're using supports a maximum GPU length of 350mm.

If memory serves, the only one coming close to that was a ZOTAC one at 325mm.

Edit: I'm blind. The ASUS TUF should fit just fine.

[Viking2121]

Should fit, I crammed a 3080ti FTW3 in a small no name brand case, tight. but it fit, your case looks bigger https://imgur.com/c9yJ8ZR

Don't confuse RAM voltage with the SoC voltage. They are two different things.

Haven't there been issues with the accuracy of the hardware sensors above ~1.3V? Hence why on Gamers Nexus they soldered test leads to their board to monitor the voltages?

[Illusion of Progress]

I'm unfamiliar of that, so may be. Regardless of what the sensors were reading, it's clear that the voltage was becoming too high in reality though.

Corsair CXF RGB is a mid-range power supply..

[Tiberius]

You alr have an aio. That aio now also acts as a backup fire extinguisher, if your cpu ever explodes 😉

[UserNotFound]

I thought there have been BIOS updates for the various AM5 boards to fix this issue, I did hear rumors that Asus has been called out for not honoring warranties due to the power boosting too high, thus killing CPUs.

Al in all, pretty glad I'd stuck with AM4, have two of 'em actually....
