A GT 740 is just not gonna make it if you want any kind of decent graphics. GTA V is very nicely optimized and you can definitely run it at "playable" fps with very low settings but that's up to you. A 500W psu is perfectly fine for a decent low-mid range gpu like GTX 1650 or even a 1660ti. Just make sure the psu has some kind of 80+ rating(highly recommended) or atleast isn't from some sketchy brand.

Okay thanx :-)
