Dell inspiron 5680 psu upgrade

Hi so I got a inspiron 5680 the specs is a i7 processor, 2 tb hdd, 16gb ram, 460w psu, and a 1060 with a underwhelming 3gb vram.

I have found that that graphics card can't pull most modern games and I was going to upgrade my gpu to something with more vram and better capabilities to go better with the i7 I'm new to pc's I've always been a console gamer I was wondering what some psu recommendations would be nothing crazy and would they be plug and play or would I have to wire stuff up again sorry new to pc gaming thank you for your time
