I have tended to favor Meanwell LRS series…
Have always ordered Meanwell LRS series SMPS when I had a preference. Might cost a bit more than competitors, but overall quality and consistency have been high and found them to be quite reliable. The only problems that I have had is when I personally created the problem. Have yet to damage a supply to point of performance degradation, despite the outright abuse in temperatures above design spec, running right on ragged edge of current limits. Have not seen any issues with EMI / Electrical Noise.

Works well and great replacement
My power supply broke in my cr10 and this was a great replacement. Interesting enough there was this random ghosting that I was seeing in my prints after replacing the power supply it has gone away. Can’t be more happy with this purchase. The fan can be noticeable on the power supply but overall its much quieter than the stock fans. I imagine if you have quiet fans you will notice the noise from this PS.

Ham/Amateur Radio, Power Supply has NO RF BIRDIES! on any H.F. Band
I am a radio amateur (Ham) that operates on the High Frequency (H.F.) Band, (80 to 10 Meters). Most other switcher type power supply’s that I previously used or tested have put out Radio Frequency Interference RFI (AKA “Birdies”) in the HF Amateur radio bands. I have tested this power supply with a 27Amp resistive load, a O’scope and Spectrum Analyzer and have found, NO dectable H.F. Birdies. The power supplies voltage output is screwdriver adjustable from 11 to 14 VDC, and is settable for 120 or 20 VAC. This Mean Well LRS 350-12 delivers 348 Watts of clean power, Just add a line power cord, you are ready to go!

Much smaller than older models and a great value! Quiet output for my ham radio.
I have three older 17A Mean Well power supplies that have been excellent performers. I needed 25A or more for my new ham radio (Yaesu FT-710) so I ordered this one. When I got it, I thought they shipped the wrong item… it’s a lot more compact than my older 17A power supplies.I added a power cord to the power supply (you have to provide your own three-prong power cord) and hooked up my radio. No line noise was detected (I do have a single clamp-on mix 31 ferrite bead on my radio’s power cord). Nice!

Great power supply for LEDs on my house
Got this to power my do-it-yourself LED strips on my house. Works great providing a lot of stable power. Fan is noisy, ut only comes on under load when the temperature is high (itâs mounted in my garage).

Good quality and great price.
Good quality and great price. Will buy again. note that switching power supplies are noisy so if you have a sensitive audio or RF application you will want to filter the output.

ONLY BUY MEANWELL
Used 20 of these Meanwell LRS-350-12 power supplies for my Fall, Winter, and New Years lighting display. No faults, issues, or defects. Ran perfectly fine in rain, snow, and temps as low as -10F

Great power for my Icom 718.
OK, so I was a bit leery about a switching supply from China that was this cheap since I had had birdies before with switching supplies on my HF gear. This seems to be working fine! I don’t have any detectable birdies, and have used it on all HF ham bands. No complaints about the power! I do wish that they would include the mounting clips and screws. Just know that you have to get both separately.
