But where the fan is attached ?
DPS2000BB PSU not working without good air flow. If you want all 2000W , you need a fan next to him.
The bracket attaches to the case via the two 80mm case fans. Two more 60/80mm fans could be bolted to the beam along the bottom of the bracket.
With the DPS2000B, you want to have as many 80 mm fans to push/pull air through those vented holes as possible. 3 Arctic 80mm fans pushing air from one side, and 2 Arctic 80mm pulling air out from the opposite side seems to work very well. Arctic 80mm 5 packs go on sale every six months or so it seems. The DPS2000BB will shut off quickly without decent add-on fans to cool it.
