This power pack gets very hot for a while at full load of 10 amps. Not only that, the fan wouldn't even turn on, so I had to plug it in directly to get it working. But the fan is not enough to cool it down. So I had to cut a huge hole in the top and make a homemade heat synchronizer for it. This PSU is very poorly constructed, it said it was well made but I don't know if it is. It almost caught fire, for a while. But I really want to just throw it in the trash and get something better.
