The power supply looks great with some quality case finishing. It measures 150mm (W) x 86mm (H) x 140mm (D) so it is relatively compact to suit a myriad of chassis designs. It weighs 1.72kg.

The top fan grille clearly allows for high levels of airflow with a full panel of large vents. The fan inside is 135mm and is said to be a high quality fluid dynamic bearing model, which we would expect in a high output Platinum unit. More on this later when we look inside.

One side of the unit is home to a power switch and connector socket. A vented panel is also in place here to help with airflow when under load.

The modular bay is split across two rows, all labelled for ease of use during the build phase. There are two 12V-2×6 headers.

The PT 1200W is capable of delivering 100A on the +12V rail, and 20A on both +3.3V and +5V rails.
