Review on Power supply 12V, 40A, 500W (Hongwei HW-12V-500W) by Adam Walendzik ᠌

Purchased for a tape 15 meters long and 14 watts per meter. The fan is very noisy and starts immediately with the inclusion of the unit itself, there is no speed control. However, this does not matter, because the power reserve of the block itself is quite sufficient. The fan turned off, from prolonged operation at a load of 220 W, there is practically no heating of the unit. The block itself does not squeak or click! I recommend!
