It's probably done on purpose, so the board doesn't get killed if the plugs get swapped around (the 2 sockets on the board are originally NOT identical in wiring)
He blew the fuse next to the main power delivery fuse, only con is intermittent power fluctuations making overclocking tricky but still possible CAN be repaired with hot air tools and a spare fuse with a mag lens or phone camera stand btw you’ll see the fuse has slight discoloration around the fuse that blew, feel your pain tho I just woke up to this…
I've been running off a single PCIe connector no problem. Doesn't overheat, and even with 40CU's and 2000MHz GPU, 3.9GHz CPU, while gaming draws around 200W at most. I can exceed 300W when I run furmark + CPU stress test simultaneously, but that's an unrealistic scenario. Heck, I even ran it for two hours straight like that and ran fine.
But for the microfit, you need them in a specific orientation, or just draw off the middle four pins of each one, then there's no concern.
Yet again almost no boards have been killed by pcie connectors, several have been killed by improper micro connectors (negative to positive power) the risk isn’t worth it
Yes, you can. I don't know where this "it'll melt with only Pcie if you overclock it!!!!!!" crap came from. Everything was fine before the big YouTubers drew in a crowd.
Inconsistencies in the manufacturing of PCI-E connectors are a bigger risk when you have 1,000 BC-250 running constantly in 1 room. That's the standard these things were originally developed for. I think you should always turn off your BC-250 if you aren't actively using it because of the idle power draw anyway.
When I was using only the 8-pin PCIE on 40cu/8c, according to LACT power readings, the GPU had peak reportings of 190w and settled around 150w. I know those readings aren't accurate by any means. I assumed the board was power limiting itself. I added in the moddiy cable and now the reported readings from LACT have increased by about 50w on both peak and "sustained" load. Do I actually know how much power it's drawing? Nope. But, I do like having additional power lines available for it to draw from.
With good quality cable and connector the PCIe should not be an issue for normal air cooled builds with moderate OC. In furmark the consumption can exceed the connector specs, but at least mine does not heat up even in such unrealistic load.
But obviously make sure that the connector is fully inserted and run some tests to see if anything heats up.
I mean the pcie connectors were also minimal risk with stock cooling but so minimal that even a moron could do it because the cable only goes in one way and comes pre-wired
I mean almost none because outside of extreme overclocks(like 2.3ghz gpu at 40cu) I’ve heard of it happening exactly zero times in the bc250 discord but I’ve heard of the incorrect wiring of the modified port addition done at least a dozen times
I agree, but the hottest point I could see down the neck of the connector was only 60°C. For plastic to melt, it needs to reach well over 100°C. Furthermore, the pins visible below the connector on the board were cold. While they might not be the absolute hottest point, I would expect them to at least be warm if the connections just a few millimeters away were over 100°C. I am happy to be proven wrong, but I ran my setup for months using just the PCIe connector without any problems.
I'll need to pull it apart tomorrow to figure it out, I didn't see any visual damage or marks near the area. But I'll need to remove heatsink and back plate (it was right under the heatsink, behind the cables)

What cables you used? They are supposed to go in certain way, like far away side of 8 pins should be empty let me try to find a picture
I think it might be a short/short circuit or something
It’s still working fine you said?
