I ended up buying GIGABYTE Geforce RTX 4060 Eagle OC 8G Graphics Card from Amazon.

When I connect my GPU, nothing displays on screen and LED on my case flicker.
Once I disconnect the GPU things start to operate normally.

I'm thinking this is a PSU issue. I'm currently using Corsair VS450 450-Watt Power Supply.

However, on the box 450-Watt Power Supply is recommended.

I do have a spare Corsair HX1000i 1000W Full Modular Power Supply from my previous build. I can try using it if its an power supply issue.

VS450 was never a very good unit. You should replace it either way.

You should probably try a BIOS reset on the motherboard, and maybe force PCIe 3.0.

With no other system details, hard to provide advice.
