MEAN WELL LRS-350-24 350.4W 24V 14.6 Amp Single Output Switchable Power

First and foremost, you always need to ensure you buy quality PSUs. These are high voltage devices pulling high amperage and are connected directly to your mains. Poor quality PSUs WILL cause a house fire. Mean Well is a well-respected brand which is known to be both reliable and safely manufactured. One way to check if your Mean We'll PSU is genuine is to look for the MW logo on the PCB. If you purchased this supply, you can find the logo right behind the fan. You may need to use a small piece of plastic to move the blades while using your flash to locate it. I've attached a picture which shows about where that is. This itself isn't enough to guarantee the safety of the device, though. Often you'll find third parties selling "refurbished" supplies they pulled out from failed devices. For this matter, the best reassurance is to check the QC Report. If you search for "Mean Well Quality Control Inspection Report", you'll find the official tool for Mean Well. Type in your serial number (found on the small barcode on the side of the device) and download the PDF report. If you bought the device new, the report should have been published no longer than a handful of months prior. Now if you want more reassurance, Mean Well states that they stamp the serial number on the PCB itself also. I wouldn't recommend this for a beginner, but you can open the device up, locate the serial number, and validate that it is the same as the number on the case.

As a 3D printing enthusiast the first thing I replace on 3d printer is the power supply! The MEAN WELL LRS-350-24 power supply is one of the best, most reliable ones there is! The LRS-350-24 delivers a rock-solid 24V 14.6A output, which is perfect for powering my 3D printer. What really sets this power supply apart, however, is its exceptional reliability and build quality. MEAN WELL is a well-respected brand in the power supply industry, and it's clear why. This unit is built like a tank, with high-quality components and a rugged design that can withstand the rigors of heavy use.

Looks like a legitimate meanwell power supply, wired up nice and have had no issues. Can’t beat the price/quality.

I had purchased some lower-cost generic Chinese power supplies. THey worked OK, until they didn't. They failed because the NTC thermistor had a lower current rating than the fuse, so the NTC thermistor failed. Not exactly great design. Furthermore, the lower-cost supply left out the overcurrent protection circuitry, so the power supply would happily run along exceeding its rating, until it failed. I bought the Mean Well supply for a price premium. And it was definitely worth it. Properly-sized NTC. And active overcurrent protection. When I put the power supply in my circuit, it shut down because I was asking for more than the rated current. This allowed me to troubleshoot my system and find out where things had failed. Much better than the cheaper power supply. The workmanship on this supply is head and shoulders above the workmanship on the generic supply, as well. And to top it off, this supply is smaller. When I needed a new 12V 350W power supply, I didn't even waste my time looking at any of the cheap ones. I just went right for the Mean Well, and I'm glad I did. For me, the extra money is well spent. I strongly recommend the Mean Well over the generic power supplies.

I’m using this as a quieter power supply for an Adventurer 5M. Watch out for the input voltage switch. Mine arrived set to 230V.

I have an Auria 27" 1440P monitor whose power supply died, a common issue with these monitors. Instead of buying an expensive replacement that's the same cheap junk, I opted to buy something a little more industrial / high quality which actually cost less. This unit worked out nicely. 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.

Meanwell has made quality power supplies for a variety of applications. I've purchased this 350W 24V version a number of times to replace the PS on a couple different 3D printers and other electronics when the stock PS is either underpowered or an inferior PS. Meanwell PSs haven't failed me yet.
