RSP-320-5 AC-DC Switching Enclosed Power Supply PFC

Mean well makes quality power supplies. I have this running about 1200 addressable 5V WS2813 LEDs that run the entire way around my living room. The built in fan runs all of the time, but it does seem to throttle up and down based on load, which is a definite improvement from most of the cheaper power supplies that have a fan that is either on at 100% blast (very loud) or off. Even at full load (or more than full load), the fan on this power supply is still relatively quiet. Much less noticeable in a quiet room than any other supply I have had. That said, there is a definite smell that comes out of the supply when you first turn it on, and for probably the first 2-3 hours of use. Really not sure what to make of that, but it went away and the supply is still running rock solid several dozen hours of use later.

It's a power supply, what can you say about it when it works? It's built solid and appears high quality, and is being used to power three 300 LED strip lights with zero issues. The fan is constant no matter the load, it's not noisy but it's not silent either.

Good and quiet woks as described

I keep these around as spares for our outdoor digital sign. They are very reliable.

Mean Well RSP-320_5 300 Watt 5 Volt Power Supply Came on Time and Works better then any other Power Supply I have had in the past! Power is constant and reliable. I was pleasantly surprised how compact it is! Powerful!

For running a 5V led light system this power supply is a must. I started with a cheaper power supply and kept having inconsistent power output but when I changed it out with this I had no issues what so ever it held 5V consistently even with a large load.

Running 275 Neopixles (LEDS) for about 5 hours a day. Max load is about 20 amps. So far, no issues. Gave it a 4 instead of a 5 because it does not come with a cover for the terminal strip / screw connections. Some power supplies have a plastic strip that covers the screws. There is exposed120vac on the terminal strip. I covered the strip with some electrical tape.The unit is mounted to a wall in my garage. Will see how it does with cold weather.

I am using one of these to power 16 Odroid XU4 computer boards. Running all of the boards uses around 240W which is 80% of what this unit can put out. The power supply easily handles the load. As others mentioned, the fan is a little loud for the amount of air it moves.I measured the voltage when I first got it and it was a little below 5 volts so I used a small screwdriver to adjust it to exactly 5 volts.It's been running continuously for several months now without a problem.I'm planning to buy another one to power more Odroid computers.
