Thermaltake TR2 700w


So we’re back doing PSU reviews. I couldn’t leave it for more than a week before I had another play with our shiny new oscilloscope could I? Today it’s the turn of the Thermaltake TR2 700w, a non modular, single 12v rail unit.

The TR2 range is a mainstream lineup of PSUs, with the RX ones having modular cabling added to the mix. This unit comes with plenty of protective systems in place and 80+ bronze certification which means it’s part of the slightly more exclusive TR2 bronze range, made up of 600, 700 and 800w units; so I’m looking at the  middle child today. Let’s see if it’s any good.
