EVGA, a company that's best known for pumping out Nvidia-based graphics cards, is so confident in its new SuperNova 1000 G2 power supply that it's backing the unit with a 10-year warranty. Of course, we learned from watching Tommy Boy (NSFW) that guarantees are only as good as what's inside the box, and in this instance, EVGA is packaging a high-end power supply that's 80 Plus Gold certified with up to 90 percent efficiency under typical loads.
Depending on how you look at things, the power supply is arguably the most important component in a build, and is at least one of the most underrated. Thermaltake over the years has worked hard to be known as one of a handful of reliable PSU brands, and its Toughpower and Smart Series are generally well received around the Web. Today both of those lines are expanding with new wattage options.
