Review on 🔌 Universal Regulated Switching Power Supply - SUPERNIGHT DC 12V 30A 360W, AC 110V/220V to DC 12V Power Driver for 3D Printer, HAM Radio Transceiver, Car Subwoofer Amp, Audio Amplifier and RC LiPo Chargers by Justin Smith

Added this to my entertainment center to run 12v led lighting. I've heard some complaints about fan noise, but mine is pretty quiet. I noticed that the fan has variable speed. The fan spins up with increasing load. My total load is only 0.5 amps at 12 volts and when I added another load of 1.75 amps = 2.25 amps the fan speed doubled but was still quiet enough that I could put it 15 feet from your chair couldn't hear while watching TV. I have a full 7.1 surround sound system so not hearing the fan probably helps. I still don't find it very loud. I like it and it works great. I got about 30 hours on the power supply at 2.25 amps on a 12 volt circuit, so I'm not loading the unit at 30 amps at all. This is the maximum score. Good power supply for what I use it for and plan to add another 2 amps soon. To update; 10/14/2020 Still working great, I added another 1 amp to the load so I now have 3.1 amps which is 10% of max load and now the fan runs louder. I need to move the power supply to an isolated location so I can't hear it now. Yes, the fan gets louder from 10% of the maximum load.
