Does the job.
When it comes to AC adapters with a Molex plug, there really are not a lot of choices out there. And if you want to use a Cooler Guys fan controller, this is literally THE one you need. And the one you will want. The Molex plug and wires are nicely molded, versus the 1980s white computer power supply plug with red/yellow/black wires I saw on another one. Plenty of length to the wires from wall to block and block to device. Plus, no wall wart to hog all your outlets. 2A capacity means you can power several fans. Does not run hot either and for a brick adapter it is pretty compact.
