PCI-E 16-pin connector (Qiyida X99 K9S)
Hello. I've been using this motherboard for some time now, and recently I observed three PCI-E x16 pins bent during a graphics card swap. This likely occurred when attempting to remove the GTX 780, which got stuck in an awkward position, making removal difficult at the time. The two cards I installed still function properly despite the bent pins, but each time I switch them, the issue seems to worsen because they interfere with proper fit. It's challenging to see, but the bottom two pins are notably C-shaped and bent, while the top one is slightly misaligned. My concern is finding a way to straighten these pins without desoldering the slot. I attempted using a needle and ESD tweezers, but the rigidity made it ineffective.
The question is unclear. Could you provide more context or clarify what you mean by "heat for"?
I attempted to clear their path. They may be fine without them reaching out. Looks like power pins are likely unnecessary since you’re supplying power elsewhere (besides the odd PRSNT1 pin). Edited August 12, 2025 by leclod
These are the power connectors. If everything functions correctly and there are no issues, it’s best to leave them alone. Keep in mind that PCIe ports are only rated for 15 to 50 insertions. Most motherboards can handle more, but that’s their intended capacity.
It's clear you're dealing with a PCIe connector designed for multiple modules. Just remember, each module should fit properly to ensure optimal performance. Avoid unnecessary swapping and focus on secure connections.
I mentioned you changed the graphics card a few times, but in reality it was just once. At first I had a GTX 780 installed on this board, which was difficult because it didn’t fit properly in the left slot. I can’t confirm it, but I think this board probably came from China with bent pins. I’ve never bent CPU sockets or PCI-E connectors before.
I purchased the kit from that listing for $71.56 (after conversion). After taking out the GTX 780 to fit a GTX 1080, I saw the pins were bent. After struggling for hours trying to straighten the second pin, it ended up looking exactly like when I first installed it. Lol I reinstalled the GTX 1080 again—should’ve used WD-40 on the slot to prevent scratches—and the board would beep five times during POST.
Oh yeah those crappy things. They are extremely low quality and basically have no qc. Its how they are so cheap that and that half the board is harvested components from server boards, the cpu's are landfill free and the memory is the same just rebadged server ram with a new wrapper on it. Not surprised it has misaligned pcie pins its not uncommon that these boards have defects like this. I'd say for safety reasons don't use this board as it is likely to wreck the gpu. Good news is that this stuff is dirt cheap. Can also go on local used market and get like a cheap x99 board if you really want stay on this socket they have become worthless basically.
