Recently upgraded all my PC parts except the PSU, My old motherboard only had a 4-pin connector and my 1050ti had none, Now I have a new motherboard that requires an 8-pin connector (which my psu does not have), and my new GPU which has an 8-pin and and 4-pin connector (again my psu only has 1 4-pin. I need advise on what to do because I have no idea what psu to buy. thanks in advance.
