I am looking to purchase a new PSU and have been eyeing the Hiper brand pretty closely. They've got some really nice looking units and they're not that pricey. However I am trying too understand which is a better rating to have: "Dual + 12V" or "4 x 12V independent rails". I am guessing that having independent rails is better but is there anything necessarily wrong with the "Dual + 12V"? Also what does PFC stand for and why is it important?
Thanks.
Thanks.
