Final piece to my build is a power supply but the G2s aren't in stock till June!
Is the difference between these two PSUs worth the wait? And is there another 750gwatts I should look into?
SN G2 is a Tier one which is very impressive, the NEX is a Tier two class B which isn't that bad either.
But what are they going to power? What about the price? You really haven't left us much info here. 😛
If we're talking a single gpu pc with something like a GTX780 or R9 290, and if the nex is quite a bit cheaper, then you should go for that instead of waiting around.
If you have something like a GTX770 SLI or R9 280X CF setup then you should go for the G2 if it's not too much more of a cost compared to the NEX.
posting your cpu and oc if you have one, gpu and any specially power consuming components you might have here, and site you're going to but either the NEX or G2 from, would help.
