I've had my PC for around five years and it originally came with a 3080 TI. Recently, I ran into some issues with that graphics card, so I took my PC to a shop for servicing. They tested my motherboard with a shop GPU and confirmed that my 3080 TI was faulty. To upgrade, I decided to go for a MSI Gaming Trio RTX 5070 TI, but it's been giving me trouble.
My motherboard is an Asus Prime Z490-P, which should work with the 5070 TI since it has a PCIe x16 slot just like the 3080 TI. After installing the new card, the PC powers up and the card's lights are on, but there's no signal to my monitor. I went back to the shop for help, and they mentioned that the pins on the graphics card aren't connecting properly with the motherboard. They noticed that although the latch on the PCIe slot clicked, there wasn't a second click indicating a full connection. They also confirmed that the slot is functional by testing it with another card. My power supply is an EVGA SuperNOVA 850 GA.
Does this situation seem accurate? Should I think about replacing my motherboard, or possibly return the 5070 TI for a different card? What's the best way to confirm if my motherboard is truly compatible with the 5070 TI, and whether it's more of a physical connection issue?

I've dealt with similar problems. If it were me, I’d probably return the 5070 TI for a new one or even another model just to rule out any manufacturing defects. Since they didn’t test it, I’d be suspicious. Also, maybe check online for your motherboard's compatibility documentation to double-check.
It sounds like a strange issue since all PCIe connectors are the same. Usually, if a 3080 fits, a 5070 obviously should too. Have the shop actually tested the 5070 TI in another setup to confirm if it works? Without that step, it’s hard to say if the card is the problem or if it’s really just a slot fitting issue.
