Is there a technical reason that power is usually on A instead of B or C? I've seen a few OEM GPUs where it's on B so I wonder why it's not more prevalent

Case compatibility. Your CPU cooler will be taller than a card slot so some height is assumed.
The real question is why the fuck aren't we supplying higher wattage through the PCI slot

It used to be on the back of the card back in like the HD4870 days (or even sticking out of the PCB on the 4870x2), but GPUs are used for a lot more than gaming now
Power on the top ensures that using these gaming cards in rack cases where there's not a lot of vertical space is difficult and requires either modification or wasting space. Notice how on the fancy workstation and server-grade cards the power is always on the rear.

?? anon you can't just make a wild assumption like this. my cpu cooler is like an inch tall

I would rather a cable melts than my entire pcie slot.

Those traces and card edge connectors can only carry so much current. Modern GPUs are getting up into the killowatt range which is legitimately hard to build connectors for. Hacking it with a card edge connector probably can't work.

But you already need to take card length into account when buying a case because a lot of cards are too long to fit some cases. In contrast, if you have something like an 8 inch long card, it's safe to assume you have enough clearance to put power there
>>106012350
This one makes a lot more sense
>>106012379
Thinking about it, the biggest guarantee you have when designing a card is that the case is at least gonna be as wide as an ATX PSU (Unless you rotate the PSU 90°, then it's only as wide as an ATX PSU is tall, but those cases only take low profile cards which you can also target if you want), idk why anon mentioned the cooler because it's one of the least consistent parts size-wise
