The be quiet! TFX Power 2 is a tiny, small form factor power supply. The unit is very nicely finished as we would expect from the German company, nothing gives under pressure and it feels sturdy in the hand. The unit passed our screwdriver test which involves running a Philips head screwdriver down the side of the chassis with weak to modest pressure. This is to try and replicate a real world situation when building a new system and accidentally connecting against the side of the chassis.

A small 80mm fan takes up position on one side of the chassis. At the end of one side is the power connector, along with vents which aid with airflow.

All of the cables run into the other end of the power supply although surprisingly they don't look to be sleeved into the metal chassis.

It has been a common trend in recent years to design a power supply with a single +12V rail, however be quiet! have split this design into two that handle 13A each, for a combined 24A. It seems obvious, but this is not the kind of power supply you want to pair with a particularly demanding graphics card.
