Btw does anyone have experience with OCing? How much headroom should I consider for the PSU?
I don’t have much experience, still in Ryzen 1st gen here. But IMO OC is not worth it on the CPU side, especially with AMD. Just hit PBO and be happy. If you want to overclock, I would focus more on the GPU side. For PSU usage, I recommend calculators from reputable vendors, like this one from Be Quiet.

Dawn, what a system. And also an infinite number of SSDs.

I’d go with 125% or more of total system power needed. An OC 5600X might pull something like 150W. But the performance gain from overclocking 5000 series is very limited

Earlier this year:
Software getting regular updates is a sign of bad design in a way.
When you need to fix bugs until the end of time, your software SUCKS.
I’ll echo this. It really isn’t worth OC’ing Ryzen. In most instances you’ll actually end up losing performance because of how AMD’s boosting behavior works. My advice, if you plan to get a 3080/6800XT or higher, get a 1000W PSU. For a 3070/6800 an 800W will be fine.

3000 series has a tendency to have voltage spikes, which may trigger OPP, if you don’t have a powerful enough PSU
This is the first time I hear about that.
There should be enough threads on this topic if you google it. Here’s one reddit thread: https://www.reddit.com/r/hardware/comments/k5lgm4/psa_3090_3080_transient_load_spikes_north_of_500w/
As I have already proved in detail in my basic article “The battle of graphics card against power supply – power consumption and load peaks demystified”, there are also higher loads in the millisecond range, which can lead to unexplainable shutdowns in the case of unfavorably designed or improperly equipped power supplies. The TBP (Typical Board Power) measured by the graphics card manufacturer or the reviewers alone does not really help in this case for a stable system design.
Peaks with intervals between 1 and 10 ms can lead to shutdowns in very fast reacting protective circuits (OPP, OCP), especially in multi-rail power supplies, although the average power consumption is still within the standard.

This^. It’s more of an issue with the 3080/Ti/3090 than the others, but they can cause power spikes for tenths of a second and crash the system. It’s not as widespread now as it was at launch, given driver updates, but it does still happen. So if you are going with the higher tier cards it’s better to just get a 1000W PSU.
I’ve been running my 3080Ti (normal TDP) + 5800X system on a 750W Corsair RM750x with zero issue so far. Though that’s because it’s one I already had. If I were building new, I would have went with a step up. Point being, if you have a good quality supply, you may not need to upgrade.

Now, we don’t want to get too crazy here, lol.
Like I said, driver updates have fixed most of the power spike issues, so it’s not as much of an issue now as it was a few months ago. So a high quality 750-800W may very well be fine, but if you are building new and spending that kind of money on a GPU then why not be safe, you know?

Not to mention if you run a poorly coded game with unlimited FPS in the menu it can still spike the power usage.

And possibly brick your card.
Though that’s admittedly a rather rare occurrence.
Unlimited FPS in a menu… common. Heck even Doom does this.
Unlimited FPS in a menu that also spikes the power usage sometimes in excess of 100%… yea it takes a rare breed of screw up for that one.

Or when pairing it with an Intel i9 or i7 CPU…
One of the biggest oversights in modern AÄÄ games, because who needs quality software when you can patch it?
That is a beast right there! I think that one has other uses since the specs are top tier, probably being used for a professional level since the Threadripper CPU is already a giveaway. Killer system right there, definitely would last long.
