12V DC Power Supply 30A AC 96V-240V Converter Adapter Universal Regulated Switching Power Supply 12Volt 360W LED Power Supply for LED Strip,CCTV, Radio, Computer Project (12V 30A 360W)

its smelly when running like that distinct chinese electronics smell but very powerful. the fan is a nice touch but a bit loud . it delivers a consistent voltage about to 65% load then it starts to sag a bit. im seeing around a .3 to.5 volt sag at near full load. which is acceptable for my usage as i dont load it fully often or for very long. the next one is going to power a 3d printer so service life will be tested thoroughly then.

Works great to power up my HAM radios on 12v. The adjusting screw allows me to fine tune the voltage to exactly what I want. My radios like 13.5 to 13.8 volts best so that is where I have it set now. Using my 25 watt radio heavily, I get very little heat out of this power supply. I just wish they would build in a digital volt meter so I could see at a glance what it is putting out. I have added a cheap voltmeter to the output side, but it would be nice if it was included.

Great little power supply! The new size works great for use in LED light fixtures, fits better in small places. Perfect for powering those LED strip light assemblies.

I bought this power supply as an experiment. I use it for amateur radio work, and it does a great job for that. It's had no issue putting out the rated power, it gets warm, but not hot, and was easy to work with. The only complaint I have is that it puts out noise in the 80m/3.5MHz band. The noise is comb shaped, and not broad band leaving a lot of the band open. It's a pain to work around, but it can be done. On all the other bands I've tested including 40m/7MHz, 20m/14MHz, 10m/28MHz and 6m/50MHz it's quiet. Even after the expense of putting it in a case, adding connectors, circuit protection and a meter, the whole project is still about half the price of comparable power supplies made specifically for amateur radio.

It is now junk, have to buy something else. NOT RELIABLE. Lasted 4 weeks

I bought this power supply for my Anet A8 as a bigger replacement for the stock 20A and wow did it make a difference. So far, I’ve been using it for about a month and have had no problems yet EXCEPT for the fact that when it arrived, there was something loose and rattling inside. My friend had also purchased an Anet and opted for the same power supply from the same seller but his problems were worse. He had an entire electrolytic capacitors come lose off of the board. This was found right after unboxing it. I was fortunate enough to be able to orient and re-solder it back in place. His unit operated perfectly after that. Just be warned that things may be coming loose in these and inspect it before you install in anything.

VERY GOOD

Don't use this in a noise sensitive environment like a bedroom. I liked the form factor and the front connectors so I'm giving this 2 stars. No more because with only 40-80W of load it makes a high pitch whining and did so since the first day I hooked it up to one strip and ran it over half power. Now a few months later with very little intermittent use (I still haven't completed the project) I finally ran it for a longer time at around 60W and the fan kicked in. It makes a loud rumble noise, like bad bearings, and it doesn't stop after dropping back to 1/4 power for almost an hour. Other people looked in the room and were worried it was going to start on fire or something because of the racket. I've had better luck with cheap 400W computer power supplies. Maybe it is just my bad luck with a lemon. I wish I had completed the install or at least done a good load test in the return window. I was planning on running 3 5m 60LED/m 5050SMD RGBWW strips with it (450W max) and as it is I'm concerned running one (150W max). I'm going to look for a different power supply.
