I bought a second-hand 3060ti, OEM blower style and have just replaced my 1060. Fans are turning on but no signal or detection that a GPU is plugged in, windows and BIOS does not recognise any GPU. Replaced my PSU with a 650W Thermaltake ToughPower (from a 450W) still no dice. I’ve tried both PCI-E slots, resetting CMOS, uninstalling and reinstalling drivers, disabled intel graphics and safe booted. My old 1060 still works when I plug it in. Also, my wifi card stops working when the new GPU is plugged in. No clue why.

Specs
I5 9600k
Asrock z390 pro4
16gb DDR4 ram
650Watt ToughPower PSU
1TB NVME

I have tried both hdmi and DisplayPort. The person I bought it from had it running in a test computer for me and did show it running with no problems.
Any ideas would be greatly appreciated.
