Question I replaced the video card and its losing video

[Guilherme288]

I upgraded my graphics card to an RTX 5060. The PC turns on, but if I open a game, besides the FPS being extremely low, I soon lose video output and the graphics card fans stop spinning. Do you think it's a problem with the graphics card or the power supply (I have a Gamemax 650W, I dont think it should be causing problems)?
