It is compatible with the AMD Fx6300. The GTX1650 will work fine with that motherboard. The GTX 650 is PCIE 3.0, and motherboard is only PCIE 2.0, but you won't notice any difference as the GTX1650 is backward compatible.
Your title suggests you already have the card and get no signal?
I'll assume this angle of approach and ask where do you have the video cable connected to? Did you have a graphics card in there before?
The motherboard has integrated HD 3000 graphics and think this is disabled when a graphics card is installed so double check you moved the video cable to the 1650's video ports.
