mixed usage , i am more casual gamer -ps4which 375W PSU is it exactly?
because of that, you might be forced to get a card which only needs one 6pin PCIe power connector at max or even less.
Which CPU are you using?
Is it for gaming or rendering or else?
GTX1050TI (without external PCIe power)
or GTX1660super /TI

The best GPU you can get that slots into your PCIe slot without any extra power cables is a GTX 1650. I recommend this card to you.
