Quad Rails. Sounds sexy doesn't it? This isn't the first PSU to be reviewed that comes with four +12v rails, but it is one of the first in the 600W range that offers 18A per rail and a total combined amp limit of 48A. We were thrilled to see an amp limit in the high 40s instead of the high 30s which is far more normal in this range of PSU wattage. With the thought of DIY (Do-It-Yourself) quad-GPU setups just around the corner, we were disappointed that none of the rails offered anything higher than 18A. We would have been estatic if one or two of the rails had offered something closer to 23A per rail, as this would have offered us more of a promise towards future expandability.
