Question about Captiva Highend Gaming I89-020 Core i9 RTX 5080

No, according to the specification it is PCI_E1 Gen PCIe 5.0 supports up to x16 (From CPU)
See https://www.msi.com/Motherboar...
I have only just received the PC, but from my point of view the graphics card is connected correctly.

Sorry, but I can't tell you anything about this, as I bought the PC for a friend of mine.

If you search for the mainboard, it actually only says PCIe 3.0 O_o
