Can I damage pcie slot by pulling gpu a little to check if it's secure?

Ensure that both the processors are installed • The processor must be of 135 W or less • The processor must use a GPU kit low-profile heat

It should work in PCIe_1 out of the box, as that's the primary slot in pretty much all consumer motherboard for a graphics card I would suggest

which gpu slot to use PCI-e slots are used for graphic cards , network cards, audio cards, etc If you don't need it, ignore the slot Depending on

which caliper is used to measure the width of the slot Without even looking at the motherboard specs I can say the GPU will need to be in the PCIe slot closest to the CPU Or highest slot if you look
