I have an hp prebuilt with an i3 7100(I know I should've built a PC but this was a hand me down) and it has a 180w psu. I'm looking at getting a pretty light card a 750ti or maybe 1050 if I get enough money. Do I need a better psu? If so what should I get

I'd never reuse a 180W OEM PSU. You should get a new one like a CX450 or CX450M.

I would definitely say so. There are quite a lot of 400-550W cheap PSU's from the likes of EVGA and Corsair. Also, do you have a fixed budget for the gpu? Because if so I'm sure we could think of something.

About $70 with a little bit of room is ideal

An i3 7100 probably averages 25w ... and will probably peak at around 40-50w.


Your choices are pretty much something <= 80w ... anything higher would be pushing it a bit.

 

so i would be comfortable recmmending a RX 560 or a GT 1050 ... in the worst case scenario you can go in their control panel and lower power by a 2-5% and you reduce the card's power consumption by a further 5-10 watts.

 

RX 550 =  45w

RX 560 =  80w

 

R7 265 = 103W
R7 260X = 93W

 

HD 7850 = 96W
HD 7790 = 78W  
HD 7770 = 73W
HD 7750 = 43W

 

GTX1050 / TI  = 75w / ~80w

GT 1030 = ~ 35-45w

GTX 750Ti = 57W

GTX 650 Ti = 74W
GTX 650 = 62W
GT 640 = 37W
