Installation into the enclosure is straightforward. Four standard screws will hold the power supply suspended in the top of the case. The fan on the rear of the unit expels the air while the two other two are mounted as intake fans. This power supply has the #1 feature I look for when I pull a new unit out of the box, a master power switch. I have gotten to the point that I refuse to use a power supply without this switch. Luckily most newer power supplies come equipped with it. The red three-position switch next to the master power switch is a manual speed control switch, offering a sort of All, Some, or None. You can either run the fans full speed, at a medium speed or let the thermo-sensing controls pick which speed is best.
