For the Psu-s
I have a question. If you have a machine what eats about 700w and you have a 850w Psu, what will you do if somhow we can overclock them and need some margin?
I have a 1500w psu and a lot of big fans to answer this.
But it's only a theory......
A 850W quality PSU will most probably be enough even for some overclocking if possible, granted a Jupiter uses less than 600W DC power.
