Either of those I'd say, Corsair PSU's are Seasonic anyway I think so it's minimal difference.Seasonic S12 500W
Corsair HX 520W
Tagan are fine, but the Seasonic and the Corsair are better overall for build quality / performance. Also if it's modular you prefer then I'd go with the Corsair HX520W, as the Seasonic and other two I mentioned are not modular power supplies.Is the Tagan no good then? or is it the Higher wattage decieving me?
Modular is prefered as well
