Today we will be taking a look at Thortech's Thunderbolt Plus Series. The Plus series has a subtle difference under the hood - having a single +12v as opposed to a quad +12v rail on the non-plus versions. The Plus series also comes accompanied with the iPower Meter, an LCD screen that connects directly to the PSU to provide critical statistics and information. The Thunderbolt Plus is available in 800W, 850W, 1000W and 1200W variants, we will be taking a look at the latter - the 1200W.
