IT WORKS, BUT…,

Reviewed in the United States on October 7, 2022

Wattage: 480Verified Purchase

The DC output is 12.2v and the voltage adjustment does absolutely nothing to change that! It still works and powers my mobile ham radio but I would have preferred 12.8v minimum and ideally 13.6v. Also the fan, while quiet, NEVER stops running. Even if there is no load! If there is power to the unit, the fan is on.

Squealing Transformer

Reviewed in the United States on March 25, 2022

Wattage: 480Verified Purchase

This PSU works, but it has a couple of problems. First, it is not a 480W PSU, more like 320W. Please read the fine print, as they do mention this. The supply can do 480W, but not continuously. 2nd problem is that under full load the transformer makes a loud squealing sound. At first, I thought it was the piezo speaker on 3D printer. After I muted it, the sound persisted. So now I need to re-engineer this piece of Chinese crap, or play roulette again and by another brand. I am very disappointed, as the PSU I replaced was repairable and only $20. This one was $15 more and I can’t repair it.

Strong and efficient

Perfect supply for 600 wd2812b leds

Reviewed in the United States on January 10, 2022

Wattage: 480Verified Purchase

This supply worked great on my 600 led strings which were turning yellow about half way from the PS. Just be sure to use a 1000uF cap to stable the output, especially if you run a multicolor program on your leds.

Not sure about this

Reviewed in the United States on August 11, 2022

Wattage: 360Verified Purchase

Box looked very rough around the edges like the shipping label was directly attached to it — but was sent in a plastic bag. Did not even attempt to open item — much less get to plug it in — for the possible fireworks show. Returned.
