Hi. i was thinking of getting a rtx2070 or 1080. but when i sa some benchmark of the RTX2070 it said the the power it needs is around 200-300 watts. I have a 750 watt PS and my specs is (GTX 1060 6gb, Ryzen 3 1300x, HDD 2TB, SSD, 480GB, MP500 240GB, AX370 gaming K3) will i have plenty of power to the GPU or do i need to get a new PS?
