This is a 12v power supply that outputs 5A to run a fan (or multiple fans).
The power supply can run about 12 DC fans with the proper connectors.

Really can't say anything bad about this product. It's high quality and doesn't run hot at all. I'm using it to power my DIM4, you can run it at fully power with no problems. Excellent power supply. Thanks Milad!

Does not get very warm even running full current

This is a good quality power supply, not a cheap fall apart china special. Only Downside is that only 2 out of 4 pins on the molex connector have power output, it was still easy enough to make this power the DIM4 controller and 6 120mm fans.
