Question Would it mean my GPU is fried?

[cloydpakinggan123]

Hello fellow tech enthusiasts! I recently just bought a GTX 750 TI for my friend looking to start into PC gaming.
The GPU was claimed to be working condition, mainly being used for video streaming.
After giving to my friend, he said the computer will not turn on. He installed it into his HP pre-built computer with 300W. I thought this was enough.

Later, I tested it on my own rig with 500W, and yet the GPU didn't want to turn on. No fans, or sounds.
I removed the connection from the HDD just to see if it would turn on. After removing the 750 TI, the CPU fans booted up as normally. However, after installing the 750 TI again, nothing will turn on...
I am wondering if this is a result of a fried GPU or just a user error.

Please provide some insight or some youtube videos, THANKS!

Notes: My rig consisted of: Ryzen 5 1600X, 500W Cooler Master CPU, 16GB 2666 DDR4, B450 D3SH

Does the GPU smell fried?

If PC won't even boot by mere inserting the GTX board in, I say is definitely fried board.

If neither of these computers can work, it's basically the problem with this card. Does this 750ti video card need power supply? Check if the connecting finger is damaged. USE an eraser or somthing esle to wipe it.
And observe the Capacitances to check if there is lose
