The black and gray label VS series units are much better than the older orange and black label VS models, but they are still units you really only want to use with basic use office or internet browsing machines, or in a pinch, maybe a machine with a lower TDP slot powered card. Also, they are not a modern design, having an older group regulated platform which you can find plenty of in depth information about if you do a search for "group regulated power supplies". These are better than any of the units down below in the wall of shame list, and better than the older VS and CX units, but don't assume you that you can simply pair a graphics card that has a 550w recommendation with a 550w VS unit and not have any problems, because in all probability, you will. These units are not meant for use with high demand gaming systems. In a PINCH, for VERY short term use, they will work, but they are not going to last under the rigors of daily gaming loads.
