Hello, i want to build a new pc, and i dont know what psu to get, i have calculated wattage of all the components and all together are 521w, the website were i have calculated the wattage recomends me to take a evga 750w 80 plus gold, but would it be fine if i take a evga g1+ 650 80 plus? (I plan to overclock in the future)

Ram--G.skill TridentZ 3200 Mhz Cl16
3x120mm fans

Nzxt Kraken m22(there is a 120mm fan included)

 
Solution
Not sure how you get 521W with that system, but you should aim at running PSU's on average about 40-70% (while gaming).
Either or would be fine, as I think your system won't be a problem with 650.
