Not sure if it helps at all, but some of the best DDR4 available for your 5600x (whether you return it or not) is going to be Crucial. Micron e-die is amazing for the value. It's surprising that nobody else recommended it.

OP built newer rig, but kept older PSU? Could well be the issue. Actually, if the prior rig was pre-Haswell, then that almost certainly is the issue, as older PSUs don't support the low-power +12V states that the newer systems utilize.
The CPU was pre Haswell but wouldn't the problem you describe make the CPU crash when under low load? That never happened, it crashed when under high stress

I don't know if this is an actual picture or if someone made a 3D render/print with known information, but it checks out in every aspect.

Let us know what the shop says.

As far as your own troubleshoot, did you ever test the system with the ram at 2133MHz?
Only thing I can think of is that your old PSU is nearing its end of life.

Absolutely. I've had it happen twice. Power supplies that should easily handle the load and have for years just gave out and shut down when stressed too much. Both times replacing the PSU fixed the issue.

It's a miracle the system functioned as well as it did with an unsupported PSU.
The problem is fixed after buying a new PSU. If I understood it correctly, the PSU is not broken but it's inadequate to newer CPUs. I think I vaguely remember choosing a different kind of PSU when building another Haswell build 9 years ago, but I didn't remember to do it now, it's been years. It's disappointing that they didn't change the connectors to indicate incompatibility.

There's the picture of the PSU that didn't work, I wasn't able to find much info about it but I don't think it's 11 years old like the 2500k because I vaguely remember that first this PC had a different modular PSU, but it's certainly very old.

I chose the overclocking profile supplied with the NETAC ram and now it works perfectly in dual channel, achieving almost the same Geekbench 5 score that's on their website. I will try to overclock everything further once I have the time. This NETAC ram is much cheaper than the alternatives here and I think it was a good deal, but I thank everybody for the suggestions.

Lots of people have warned me about Thermaltake before. I almost went for their 550W coz it was the cheapest. Good thing I didn't.
