Corsair or enermax are the main two brands for PSUs
The thermaltake toughpowers are pretty good (same psu as the corsair tx series), both manufactured by channell well tech. However the lower priced purepower models dont seem as good from what ive seen. Currently running a toughpower here, 750w though ill be replacing it with a modular corsair hx850w.what about thermaltake akasa ect lots to choose from
