I'm building my new PC tomorrow and was told my Corsair CX650M 650W 80 PLUS Bronze certified PSU is good enough for my new i5-9600K and RTX 2070. Was I told correctly? They did say I'd probably need to update the PSU in a couple years, but this PSU is only a year or so old when I got it with my 1050Ti (a bit overkill at the time on the PSU - but I was upgrading from a crappy stock no name PSU from a prebuilt PC).
