My PSU died a couple day ago. I'm looking at replacing it with an EVGA G3 750W, which has 62.4 amps on the 12V rail (I was using an 850W, turned out I might not have needed that much power). I'd like to upgrade my video card (I have an RX480 now...I was thinking of going to Navi...I don't care about ray tracing, plus the RTX cards are very expensive...I suppose I could get a 1660Ti possibly). Anyway, my question is, has anyone been able to find the amperage required for video cards outside of looking at the retail box? I would hope that 62.4 would work for Navi or the 1660 card, but I would hate to buy a new power supply, buy a new video card and then realize too late that the amperage isn't enough. I have searched on Google for a rating for current cards and haven't had any luck.
