    Works Computers and Accessories

    Works. I set it to 24.78 volts. Although long, it fits my printer perfectly (the measurements given are accurate). The fan is quite loud, but for its size, I'm not sure there's anything you can do about it. It actually heats my questionable printer bed to 90C and keeps it (my printer is a TEVO Tarantula Pro. Pass it on to TEVO) which is 10C, so ABS and PETG are now (finally) possible.

    • Handsome
    Cons
    • High Price

    Not for radio amateurs with my system

    I bought this to use with my Icom IC-7000 and the voltage was set and everything connected correctly but as soon as I turned the radio on it caught to jump. I double checked everything, everything was connected correctly, hooked up a different power supply to my radio and I had no problems. Returning it was easy, all I had to do was wait for the money to hit my account. The seller was very accommodating and made it easy to return the item. I think the power supply will work in other…

    Mean Well quality for other CNC machines

    Great quality and reliability from Mean Well. I'm building another CNC machine and I'm not even thinking of using another manufacturer's power supply. Only thing is there is NO terminal block cover in the kit. I will fix this with a 3D printed part. Be careful if you don't have it or can't make it.

    • Feel good

    Ender 5 - so far so good

    The power supply my Ender 5 came with broke down recently. The voltage drops sharply under load. This device is a replaceable replacement. I can't comment on the build quality, but there's a picture of a MeanWell and Landy power supply to the side. I've noticed that MeanWell's fan doesn't work when the PSU is cold. It starts when it gets warmer. This is a pretty neat feature. The fan is also a 12V model, not 24V like on the Landy. As this fan can be a bit noisy I may change it to something…

    Works well and great replacement

    My cr10 broke the power supply and it was a great replacement. Interestingly, after I changed the power supply, that random ghosting I saw on my prints went away. Couldn't be happier with this purchase. The fan is noticeable on the power supply unit, but overall it is significantly quieter than standard fans. I think if you have silent fans you will notice the noise from this PS.

    Pros
    • Few competitors
    Cons
    • sad packaging

    Great outdoor power supply - highly recommend

    I bought this power supply to replace a broken wall power supply. Since I needed this to fit in an already cramped outer case, the small size was ideal and the rail adjustment allowed me to set the tension just how I needed it. It will be a bit more expensive than a cheap pre-packaged accessory but I have used several of these Mean Well accessories and they have proven to be extremely reliable and consistent.

    Pros
    • Absolute legend
    Cons
    • Ugly packaging

    Compact and affordable from a reputable brand but noisy

    I'm using this to easily power a strip of around 200 ARGB LEDs, but I'm not going to push this power supply anywhere near its limits. nominal maximum. Pros: Fairly compact compared to more powerful 5V power supplies from Mean Well Passive cooling (no noisy fan) Convenient screw holes accessible from the front of the unit (on the 350W variant that I also have, those were Screw holes maybe only accessible from the back ) Cons: - my unit has a noticeable coil hum that changes tone with different…
