Arcity 5V 12V 24V Output Switching Power Supply Unit Adjustable for Video Multi Games Machine Console Cocktail CCTV Computer DIY New

It's Ok, Good quality and cheap

Works great and runs cool.

I have two of these power supplies. They are great for little projects. The voltages are stable. No over heating. Audibly quiet. Have had any issues with noise in the RF spectrum.

It’s a nice power supply with 24, 12, and 5 vdc capability. However it tends to get warm and I suggest using an external fan to keep it cool since it does not have one built in.

I have mine set up to power a raspberry pi (5v), case fans (12v) and USB multi-port charging (24v using 24v-rated charging assembly). Have other, similarly designed, dedicated-voltage PSUs running other components. My application is a home entertainment station (arcade, house-shaking jukebox (dedicated 24v/15a supply), charging station, 4 touch screens for sports and whatnot). This device works well in its role. Know your load! When you look at this and wonder if it does 5v/8a, 12v/7a, AND 24v/5a, the short answer is NO. This unit runs a single power rail, so load on any voltage output will affect available amperage on the others. The reason you see different power ratings at each voltage 5v/8a (40 watts), 12v/7a (84 watts), or 24v/5a (120 watts), is due to efficiency and energy loss during conversion, as you generate more resistive heat by dropping 120v to 5v than 120v to 24v. Each of the individual voltage/amperage ratings is the theoretical max when ONLY that voltage is used. Anyway, understand that you aren't going to get 40+84+120 = 244 watts out of this thing. You'll need to do the math for your application, if you are trying to push the upper bounds of this power supply. Or, if you plan on maxing at each voltage, consider dedicated power supplies. If you keep max load under 80% or so for the unit, you'll get less heat and longer service life.

Works great in my arcade cabinet. I needed 24v with enough amps for an amplifier and this solved my need. My only drawback is there are only a few mounting holes and they are pretty small. The 5 volt output is adjustable.

died after only 6 months

As an electronic hobbyist this is perfect for my test bench to power the various gadgets I build.

It works just fine with a little devise i am building. I would like to know though, whether i put it in 110v or 220v mode it appears to be working fine with 110v. I want to plug it to a 220v source, but i am unsure if the switch is real, because in both modes it works well when plugged to 110v

Would buy again

Pratique et utile . Polyvalent , nous pouvons utiliser la tension nécessaire à notre choix. La tension en dc est de 5vdc-12vdc et 24vdc dont le 5vdc ajustable. Je m'en sert pour les projets Arduino , sur les cnc machine. Je le recommande. Bonne journée. A

After a month of usage on my 5 Nema 17 steppers (max 8A when all running, only 2 run at a time), it started smoking and the destroyed the voltage regulator on my circuitry

Works well for my application.
