Seasonic has built a stellar reputation for themselves producing some of the best PC power supplies on the market. Over the years, Seasonic has been the OEM (Original Equipment Manufacturer) of choice for companies like Corsair, PC Power & Cooling, and XFX to name just a few. But Seasonic also markets power supplies under their own brand name. The Platinum 660W/760W/860W Series is Seasonic's newest flagship line for the retail market. We will be taking a detailed look at the Platinum 660W model in this review.
