Customers are satisfied with the adjustability of the power supply. They mention that it has an easy-to-adjust voltage pot that can be rotated to adjust the voltage to the exact 24 volts.

35 customers mention12 positive23 negative

Customers are mixed about the noise of the power supply. Some mention it's very quiet, making the printer much quieter. They also say there's less fan noise and no weird ringing. However, others say that the fan is a little loud and makes a significant amount of noise on the 24V output when it kicks on. This can be mildly annoying in a quiet room.

"...Much less fan noise and no weird ringing. Printed a mount to install it at the back underside the rear of the build plate and out of the way...." Read more

13 customers mention9 positive4 negative

Customers are mixed about the temperature control of the power supply. Some mention that it runs fairly cool, while others say that it doesn't get too hot. The built-in fan is temperature controlled, allowing it to improve print quality and reduce heating time. However, some customers say that the fan included is not controlled by temperature, it simply runs at 100%. The fan does run most of the time, but it's quieter than the Prusa PSU.

"...I like that it has a built in fan that is temperature controlled." Read more

"...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

"...the noise on the 24V when heating the bed and as a bonus has a thermal operated fan. My printer is now silent when not printing...." Read more

Appear to be genuine, likely from resellers
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.
