OCZ added on to their PSU profile this week, with the introduction of several new ModXStream Pro power supplies. The PSUs are aimed at enthusiasts, like most OCZ hardware, being sold as units built for reliability and stability. The units are available in configurations from 400W to 700W, and all of which carry at least an 82% power efficiency rating, even at full load.
The latter is important when dealing with heavy loads, since a more efficient unit is less likely to fail when put under the stress of, say, multiple GPUs. They are modular units and support every other feature you'd expect from OCZ PSUs, such as Active PFC. You can read more about the units in the press release.
