So, for that graphics card, for gaming, and ignoring the "play pretty much any game smoothly" comment since that's really not very realistic with a GTX 1650 Super when there are games out there that we know cause even an RTX 2080 ti to sweat depending on the resolution and settings, I'd say that based purely on the graphics card model, this probably a really good match considering that if you're going to go with a K sku motherboard you probably want an unlocked CPU. Anything larger than this CPU is probably a waste since it will be grossly outclassing the graphics card.
This CPU could be used, well, with pretty much any compatible graphics card you might upgrade to down the road or if you decide to go with a somewhat higher graphics card, which to be honest, if you plan to play "any game smoothly" and assuming the resolution will be 1080p, might be a good idea. I'd say the 1660, 1660 ti or 1660 Super would be a lot better, although clearly more expensive, choices.

Thank you I will use the 1660 Super graphics card instead then because I dont want a bad card I just dont know much about them.
Anything less than that CPU in terms of cores, will probably suffer in some modern games.
Do you already have this motherboard, or what is the reason for the motherboard selection and what exactly do you ALREADY have, if anything? If you don't already have some of the hardware, or even if you do, what is your actual budget if there is one?
