As far as the numbers are concerned, the EvoStream 600 is designed to handle a continuous load of 600 watts. It makes use of four 12v rails, each of which are rated at 15A. While this isn't the beefiest setup on the block, it will be sufficient for all but the most hardcore systems. Our test system runs a pair of hungry video cards and no issues were noted even under load. The 5v rail is rated at 30A and the 3.3v rail is rated at 20A, so even older Athlon based systems should be well provided for.
