5V 40A Power Supply AC 110V/230V to DC 5V 200W Universal Regulated Power Transformer for LED Strip Lights

Using this to power a security camera in a porch, taking the permanent 240v to the motion sensor on the porch light and feeding the 5v to the camera. Been installed 3-4 months now and worked flawlessly.

Working well with the christmas lights.

Does the job, easy to use and works well. One downside would be the terminals connected to the 240v input could do with better protection against electric shock. Perhaps the designer can split the clear plastics flip down lid that protects the 240v input contacts and the 5v output contacts. If you have children around be sure to secure this unit out of reach otherwise there could be a risk of electric shock or electricution

Good PSU, I used for LED supplied with DigUno controller, although I think it could have a fan built into, as can get hot a bit

Bought to power two RGBW LED strips comprising of 259 LEDs. Each LED has RGB+W so I am draining around 60mA x 259 worst case appx 15A. Mounting holes have allowed me to affix vertically to the underside of my workbench in a narrow unused space tucked away (see photo). I have kept powered, with LED at full and the PSU remains cool with no noticeable volt drop. The metal work is quite thin, not flimsy, but would not take a lot of pressure to disform. Given the price, very please with the product.

It does exactly what I need, runs 1024 leds on a massive matrix and a microcontroller with no issue

Bought this to supply 5v 5a to 5 servos controlling home made automated blinds. Worked so well i bought another to do the downstairs ones. Smaller than i expected which is good, gives a slight hum while its powered on, its not too noticeable unless you will keep it by your bed (i resolved this with a wifi plug). The mains guard could be better but i stuck mine in a junction box to keep it all tidy and safe. Highly Recommended .

As many have already provided feedback, I just add something maybe new and useful for some. I've just measured idle consumption: ~5W (nothing connected on the DC side). Because the PSU will be hidden with no on/off switch within convenient distance, I intend to use a remote RF based mains plug to switch on/off.
