Best Power Supply for i7 8700k – Do you think that 650W PSU (seasonic gold prime class PSU’s or similar quality) will be enough for upcoming i7-8700k CPU paired with GTX1080Ti?
I thought it will when I was comparing i7-8700k and i7-7700k TDPs that are about the same (i always thought TDP comes in pair with power draw).
But in recent entry in Software reports for i7-8700k you can see there “Average Power 308.5W” whereas i7-7700k in most of reviews didnt draw more power than 140W.
Is it realistic that i7-8700k will require twice as much power as i7-7700k with “just” two more cores?
I was 100% sure that for i7-7700k + GTX1080ti 650W PSU and thought it will be enough for i7-8700k too but now i started to have doubts if i shouldn’t go for something higher like 750W.
