Upgrading from a strix 3070 to this is a huge performance jump. It is a very power hungry gpu. With slight overclocking through msi afterburner have seen the power draw up to around 470 480 watts. I'm sure some others have pushed this thing well over 500w but for the relatively small work load I do it's definitely overkill for me personally but I do love the extra performance gain I get from this card. Overall I give 9 out of 10 would recommend
