If amperage is your delight then you owe it to yourself to check out super flower. I plug them every chance I get here in the forums. They are slowly gaining a following, I'm part of it. They come from the same factory Enermax PSUs come from. The rails on their higher wattage models are excellent, but they kind of stray on their lower wattage models. They all come with an internal POT for tweaking the rails, too.
