There is no such thing as a "gaming" PSU. A PSU simply converts the less stable Alternating Current (AC) to a more stable Direct Current (DC). There might be some designed to look more gaming oriented, but the design doesn't really matter, unless it's about the fan. About your PSU, it looks good, and, if you've done your research as to not overload your PSU, it should work fine. Brands that you want to go with are Corsair, NZXT, EVGA, XFX, Seasonic, etc. Brands you want to stay away from are Raidmax, Coolmax, etc.
