External Examination:
In the first picture you can see the flawless paint job on the power supply which has a dull gun-metal finish... I prefer this finish to the fairly common mirror finish. Turning to one of the sides, you will find the standard electrical rating sticker. As you can see, this unit provides 20A of power to each of the 12V rails, while providing 26A to the 3.3V, and 28A to the 5V rails. In addition, Tagan has provided you a chart of the TSCT (Tagan Silence Control Technology), which gives you detailed noise level information at various fan speeds.
Many power supplies are opting to use 120mm fans, which can allow for slower and quieter operation, while still maintaining a high level of airflow.
Tagan has implemented two 80mm fans. The first is an intake fan, which will blow air across the internal components, while the second fan will push the air out of the back of the case. As you can see in the first picture, Tagan has used a standard 7 blade case fan situated behind a fan grill for the intake. If you look closely at the cables you will also notice Tagan has done a nice job at protecting them from rubbing against the metal case.
In the next picture we can see the back of the power supply. First we have the standard power plug and a large hard power switch. Next to those we can see the exhaust fan. While the intake fan was a standard case fan, the exhaust fan is a little different. This fan uses 11 blades instead of the 7 on the intake. Another difference is the exhaust fan blades are dimpled. I first encountered a dimpled fan on a fan made by Sharkoon. I found this to provide a high level of airflow, while keeping the noise level to a minimum.
