"...Fortunately, this power supply measures its internal temperature and will only turn on the fan when needed, which is way more convenient, and..." Read more
"...The only downside for this particular PSU is that it's actively cooled with a small fan, and that fan is a little whiney...." Read more

There was a problem filtering reviews right now. Please try again later.
I have several of these in-use for various projects, from 3D Printer and CNC machine to some projects still in development. I also have various other meanwell PSUs in use for lower power applications like LED lighting and such.
The only downside for this particular PSU is that it's actively cooled with a small fan, and that fan is a little whiney. I know a few folks have researched into alternative quieter fans (many of which don't actually push enough air, and don't meet their listed specs), but to be honest it's not noisy enough to really be an issue for me, so I haven't bothered replacing the fan.
The fan isn't on all the time (e.g.: not when 3D Printer or CNC are idle, and not driving motors/heaters etc), and when it is on the noise is drowned out by the noise of the rest of the equipment (stepper motors, CNC spindle, extruder hot-end blower fan etc)
The original power supply was a 24V DC 6 amp unit, so power draw should be 140 watts or so max. I chose this 350W power supply because I figured I'd rather go overkill, and my thought was drawing 50% power (probably much less) would keep the fan quiet or not coming on at all. That was a reasonable assumption but doesn't quite work out in practice.
For the first 5-10 minutes of use, the fan simply doesn't run. If you leave the monitor on long enough, it will kick on which is mildly annoying in a quiet room. Fortunately I have 4 kids, so there's always noise in my house, so it fades into background noise and doesn't bother me.
I've touched the case when the fan comes on, and it's cool as a cucumber. I suspect I could disconnect the fan entirely and the unit would run plenty cool enough for the power I'm drawing from it. But I just leave it be, as this is a secondary monitor for my PC that I don't use much.
I've used Mean Well power supplies in more industrial/commercial settings-- I worked for a pipe organ builder where I used to purchase them-- in that application, it takes 15V DC anywhere from 30-150+ amp and the Mean Well switching power supplies were top notch-- lot of bang for the buck, and I never had to replace one prematurely.
So far I've had no issues and print 24/7.

It's neither refurbished nor bootleg since the inside has no dust and the major components are Mean Well branded.
