This is a basic switching power supply without any embellishments like cooling fans or overvoltage protection. It's a fuse protected rectified line side arrangement with switch mode bucking topology. All what you would expect at this price point. The design is minimalist, with only what is needed to get the job done, and that's fine for the price point. Being Chinese made with non-premium components (no Sprague, Dale or Ohmite here), the lineside capacitor is a 100uf 450v Dongbaohe brand, with 5 x 1000uf 16v WCO brand as final DC filtering. Despite being minimalist, it's well executed, with good build quality. Soldering is well done automated work with a generous amount of solder fillet on all leads. Long term stress cracking shouldn't be an issue as is common on some of this style PSU. I wouldn't use it in an industrial or any critical application, or use it to power equipment which could be damaged by overvoltage or excessive noise, but for hobby, shop, LED lighting or experimental use, it should perform well. The power supply came out the box adjusted to 5.02v, and holds it's output well under load. At heavy loads, it produces moderate heat, with little concern for overheating as long as it has good airflow available. I would mount it vertically if possible to take advantage of convection. If installed in an enclosure with limited air circulation, derating would be advisable. Adding a 5v fan would be a nice improvement, as would some additional output filtering, and an output fuse. All could be done quite economically. For it's niche, this is a really good value, and I plan on keeping at least one on the shelf for when I need a quick 5v PSU solution.

I've been using this PHEVOS power supply for a few months now to power my Arduino, servos, and servo testers during development, and it has worked perfectly. The material is good, and the fact that you can regulate the voltage is a nice feature. It's also very versatile, and can be used to power a variety of other devices, such as CCTV camera systems, radios, LED strips, and pixel lights. Overall, I'm very happy with this power supply. It's well-made, reliable, and versatile. I would definitely recommend it to others. Pros: Well-made - Reliable - Versatile - Voltage regulation Cons: - None that I can think of Would recommend: Yes

nice cheap bench power supply

Currently being used to power my Raspberry Pi's. With the 12 amp available load, you can power almost (5) Pi 3B+ units at the same time, or (4) Pi 4B units all at the same time. As with any electronic device that needs to be manually wired into Mains power, be mindful of how it's wiring up, unless you'd prefer using it as a really shiny, heat dissipating paperweight. Currently using it to power (2) Raspberry Pi 3B+ units, one for RetroPie, and one for PiHole. Flawless power delivery to far, it runs 24/7, 365 days a year, and I've yet to have a problem with it. Make sure to power it up and tune the output voltage so it's exactly 5V.

This 5v 12A supply arrived in good shape with no damage and was set to 5.1v out of the box which is reasonable. It has worked well for the last month, but I’ve only put about 5A of load on it. At that level of current, it runs cool so it is reasonably efficient. Internally it looks similar to other “frame” style supplies with old school through hole components. It is fused and the heat producing semiconductors make good contact using thermal compound. I’ve purchased similar power supplies that come with no thermal paste and poor frame contact so this was good to see. There is an input filter, L1/CX1, which should keep any noise from back feeding into the power input. The adjustment resistor goes from about 4.9v to 6v. I would have liked to see a tighter range than a full volt, 4.8 - 5.3v would be better. Most people won’t care, but I always worry that a bump to the potentiometer could cause it go too far out of spec. No doubt one could fix this if they want to go through the effort and have the expertise. I’ve done it on other supplies and it usually requires changing one resistor and the potentiometer. I would recommend this for those that have the expertise to test/set the voltage, and can safely wire it to mains power.

I've gotten quite a bit of use out of this power supply, I originally purchased it to run a 12vdc car power amp, later I was using it to run a 12vdc battery charger for my RC Planes and recently I've put it in a homemade boom box running a 12vdc marine radio and use it in my garage and on the back deck to Bluetooth music from my phone. It's always worked flawlessly and runs very cool.

The raspberry pi 3 supposedly needs a 5v 2.5 amp power supply. No matter what I plugged it into, it would give low voltage warnings. I even tried plugging it into my Tablet's 5.2v 3A plug and it still gave the error on occasion. When I used my usb tester on them, it was always under 5 volts so they wouldn't put out good current and voltage unless it was used on their own device. I got the 5v 60 watt power supply and set it to 5.1 volts and I'm getting no errors. I tested the output voltage as I was expecting and it was still outputting 5.1 volts. I am currently powering a Raspberry pi 3B, an SKR 3D printer board (to keep the board in sleep and accepting a power on command when it's not on 24 volts, a MOSFET to control and dim the printer head lights via M355 command, and a power control relay to turn on and off the 120 volt going to the 24 volt power supply with M80 and M81 commands respectively. it's a bit overkill, but does the job well.
