PC don't turn on when using gpu

Hi I am facing weird problem with my system. I am not able to figure out what exactly gone wrong with my PC.

My system specs are as folllows:

CPU: AMD Ryzen 2600

Motherboard: Asus ROG B450 Strix Gaming.

PSU: Antec 550Watt Neo Eco.

RAM: 2x8GB Corsair Vengeance DDR4 3000Mhz

GPU: GTX 1060 6GB

Whenever I try to turn on my PC it won't boot. Nothing happens, no PSU fan start, no CPU fan starts, no motherboard indicator LEDs lighten up. I thought my PSU got some issue so, tried to use my secondary working PSU but still problem didn't solve. I also visited Asus service center for motherboard issue, there they checked my motherboard with their test system and it booted fine. I went back to home without repairing my motherboard.

After returning my home, I removed everything except CPU, CPU Fan, GPU and RAM and tried to start by shorting motherboard power pins but still it didn't turned on (Same problem). Then I removed my GPU and tried shorting motherboard power pins and luckily every thing got working i.e. PSU fan started, CPU fan started, and motherboard LED's lighten up. What I understood is if plug my GPU my PC won't even turn on its like a dead PC, but once I remove GPU it starts. I tried to plug my GPU to another PCIe slot still it didn't solve the issue.

I reached to conclusion that my GPU got dead, but then why it didn't start with dead GPU like it started without GPU? Any reason?

If the GPU card has a dead short on it, the PSU will shut down immediately.

Visually check the GPU card and see if you see any burnt marks on it or anything that looks like it shorted out.  Check the Fan wiring on the GPU card and the Fan assembly itself and see if you smell or see anything that looks burnt or shorted.

If the GPU card physically looks normal try installing in another PCIex16 or PCIex8 lane on the motherboard.

Try using a different GPU Card and see if it boots up. If it does, then I suggest you RMA the Nvidia GPU card back from the retailer you purchased it from or from the GPU Card manufacturer.
