MIG-31

ABT-450MM is one of the most low-end power supplies from Kingwin, targeted to users building a very basic PC. Kingwin promises that this power supply can really deliver its rated power at 50º C. Is that so? Let’s check it out.

As you can see, this power supply uses a big 120-mm fan on its bottom (the power supply is upside down on Figures 1 and 2) and a big mesh on the rear side where traditionally we have an 80-mm fan. We like this design as it provides not only a better airflow but the power supply produces less noise, as the fan can rotate at a lower speed in order to produce the same airflow as an 80-mm fan.
