Page 98, Table 17, Row 3: Reveals the stock turbo power limits for the 13900K and 14900K CPUs are 253W, not the 4,000+ my MB's Bios settings default to.

Intel is slowly getting crazy with their power consumption.
But in all seriousness. From what I've heard in the last few months, many ASUS boards just give more power than the CPU is rated for. This supposedly killed a lot of AMD chips recently. 4kw still seems like an error. This ain't an electrical vehicle.
It just damaged mine, it was crashing all the time before I messed around and tried power limiting mine. It was about 2 weeks before it got revealed that it was a wide spread issue.
I don't think I caught it early enough, though, because I have a lot of problems with my USB controller. It can only handle like two or three devices plugged in at a time before things stop working. But, technically, it still works, so... I think I'd have trouble making a warranty claim.
the stock turbo power limits [...] are 253W, not the 4,000+ my MB's Bios settings default to.
The comma makes me think you didn't add an extra zero by mistake... What in the actual fuck? I admittedly haven't messed with any CPU clocks since like 2014, but an increase of nearly 16x over stock feels like absolutely bonkers nonsense. Like that just seems so out of spec that your computer should just catch fire. Like the hardware shouldn't even allow it.
In fairness the motherboard not restricting power usage isn't a bad thing: it's not like it's shoving 4000w through the cpu, it's just letting the cpu pull as much as it wants which, with a non-defective piece of silicon, is probably fine.
A modern CPU shouldn't pull enough power that it kills itself, unless there's a major failure in design or manufacturing.
Sure, the CPU gets hotter with more power and sure, the last 5% of performance is a third of the total power usage and probably not worth chasing, but them's the design decisions x86 vendors are making right now and the motherboard (assuming it can deliver enough clean power) shrugging and saying 'whatever' is, outside factors aside, fine.
Also, that 253w TDP limit on a i7 or i9 is a bit low. Yes Intel's spec says that, but intel lies like crazy on power usage, and pretty much always has. These are chips that will happily gain performance up to about 400w of total draw, so capping at half that is a bit of a kneecapping, though it MIGHT keep them from failing as fast, but who knows.
