Hi everyone!

I bought a GeForce RTX 3060 GPU to replace my old GeForce 1650, and any time I connect my 8-pin 6+2 pin to my computer and the PSU, 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 reinstall my old GPU the PC 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.

The screw next to the 8-pin power RTX 3060 connector looks suspicious. If the card is second hand, the previous owner may have pulled the cooler off and made a mess of repasting it.

By the sounds of it, the PSU is detecting a short circuit on the 8-way PCIe lead when it's connected to the RTX3060 and OCP (over current protection) in the PSU is kicking in.

The computer won't work if it detects there's no auxiliary +12V power on the RTX3060, so there's no point expecting anything to happen with the 8-way PCIe lead disconnected. That's why you're seeing a white light.

Chances are your RTX3060 is dead. Sorry.

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?

Please don't lay your graphics cards down on the brown carpet (at least that's what I think it is). Carpet is one of the worst things for inducing static voltages, which can zap your cards with ESD. Similarly, don't lay the computer case down on the carpet with the side panel removed, exposing the rear of the motherboard to possible ESD damage.

The international companies I worked for spent millions equipping their test labs and manufacturing areas with ESD protection.

Of course if you keep your fingers crossed, static damage will never happen, but it's better to play safe. Components damaged by static can work for months or even years after being zapped, before mysteriously dying.
