I have an "ASUSTek COMPUTER INC. PRIME H270-PLUS" MB (as shown exactly from CPU-Z).

The board has these slots:
one PCIe x16 used for an ASUS GTX1080 ROG STRX video card
one PCIe x4 used for another identical ASUS GTX1080 ROG STRX video card
three PCIe x1 expansion slots
i wanted to add usb c (or thunderbolt 3!) support so i recently purchased a
"StarTech.com PCIe USB 3.1 Card - 2X USB C 3.1 Gen 2 10Gbps - PCIe Gen 3 x4 - ASM3142 Chipset - USB Type C PCI Express Card (PEXUSB312C3)"
from amazon: https://www.amazon.com/gp/product/B087G7T234/ref=ask_ql_qh_dp_hza
this does not fit in my mainboard. it is advertised as PCIe, and i have PCIe slot available, but (and this is where my ignorance shows)
from where the "key" (?) is on the connector part of the card, the length of the front half of the controller card is shorter than what is on the MB, and the 2nd half is longer.
if these are indeed BOTH PCIe, why are they different / opposite?
Please note: i have already returned the card to amazon, but i still need to know whats going on so i can make an educated purchase.
