Corsair's CX650M, Riotoro's Onyx 650w or Seasonic's M12II-620 EVO. Which one should i get?
Note: the online psu calculator says that my build will use about 480 watts, and recommended a 550 watt PSU, but decent 550 watt PSUs are just impossible to find here where i live (there's EVGA's 550 GD, but i don't really trust it), and i can't buy from abroad.
Thanks in advance.
