upgrading graphics and psu

hey i have a Dell Inspiron 660s and I was looking forward to addimg a Gigabyte GTX 770 since I heard it was compatible, but I also heard that I would need to have at least a 500 watt power supply. I currently have a 220 watt. Is it possible to upgrade the power supply? If so, which power supply should I get?

Inspiron 660s is a small form factor that was released in 2012.  In my opinion, it is not worth it to invest significant amount for upgrade.  New power supply, graphics card need to be outside the case.  Hundreds of USD spent may not yield the performance you are expecting due to its limited space and cooling.

A slot powered low profile card with up to 75w may be a feasible upgrade option.  See suggested upgrade options from here  https://www.hardware-corner.net/desktop-models/Dell-Inspiron-660s/
