Question Bought a GeForce RTX 3060 to replace GeForce 1650, Computer won't turn on.

Hi everyone!

I bought a GeForce RTX 3060 to replace my old GeForce 1650, and any time I connect my 8pin 6+2 pin to my computer and power supply nothing happens. If I leave the power supply connected to the GPU my computer is completely silent, no fans turn on, lights on the motherboard do not turn on, nothing.
After removing the 6+2 pin from the GPU end and turning the computer back on, everything comes on. but my computer only has power and won't load. The white light error light turns on for the computer indicating a issue, and when I reseat my old graphics card it starts like normal. My motherboard still works.
The GPU and every other component is seated properly. I also updated my BIOS with the old graphics card after checking whether the B460M PRO-VDH motherboard I have is compatible with the GeForce RTX 3060.

I have a comparison of the two:

I would appreciate any help! I'm thinking at this point I either need to buy a different motherboard or upgrade my PSU to a stronger wattage.

How old is the PSU in your build? Have you tried powering the new GPU with a PSU that's got 650W of power at your entire system's disposal(not just advertised) from a friend or neighbor who owns a reliably built unit?

Speaking of new, is the GPU used? If it was, did you verify if it was working before you purchased it?

I also updated my BIOS with the old graphics card
Did you clear the CMOS after verifying your BIOS was successfully flashed to the latest version? Speaking of BIOS what version are you on at this moment of time?
