Kastar 12V 6A 72W AC Adapter Power Supply

Ms Lowell: Plugged this into my grow light, works like a charm.

RogerD: Sadly I don't know enough about electricity, specifically determining power supply needs.

I needed a 12V DC power supply for Peltier Junction & PC fan cooling application.
But wasn't really sure about the amount of current needed.

The Kastar AC Adapter Power Supply did run for 10 minutes or so, then stopped.
The power supply was very hot to the touch.

I was able to cannabilize another more robust power supply, from another of my projects, so wasn't stranded.

The biggest incentive, for purchasing the Kastar AC Adapter Power Supply, was that it included the nifty connector.
Including the connector just made it an easy implementation.

A word to the wise.
Make sure to size adequately.

Dale Turner: Not really sure, as I bought it with to go with a Mini-Box picoPSU-90, but it won't power on my Gigabyte J1900N-D3V.

Joelle: The one I received has 3 prongs and no "Kastar" label. I only used it for white LED strip light (about 13-14 feet) and I made sure I have less that 4A load on it (around 3A). I saw some post that measured the max load to be 4A so, just to be safe, I stayed beyond it's limits. Using my kill-a-watt, It is measuring at 0.3-0.4 watt with no load consumption which maybe because of the LED light to indicate power is on. My Motorola 12v 3A router's PS registered "0" with no load. It gets hot after a few minutes of use but that seems normal. I just make sure it is not next to any drapes just in case.

I purchased a used higher capacity power supply from Craigslits and the person I bought if from is a professional LED strip light installer. He gave a good point to use UL listed PS from old monitors/PC. Not only that it's cheaper, it's reliable, and not a fire hazard. The one I bought doesn't even gets hot. After some browsing in ebay, I could have gotten it even cheaper, but it did not even come to my mind of getting those and replacing the end connectors with DC power plugs.

Marc A. Speth: I bought this power supply to replace another power supply that had caused major havoc with my computer. This power supply works wonderfully!

I recently bought a cheap 12 volt power supply (that LOOKED a lot like this one but was NOT this one) to replace the wimpy power supply that came with the Lepai 2020A+ amplifier I connect to my Apple iMac. The very first time I went to plug in the audio cord to the computer there was a spark from the plug to computer and the computer went dead. Three weeks and $850 later to replace the logic board and the power supply in my Mac I had my Mac back.

During that three weeks I learned that SOME power supplies have half of the supply voltage floating on the DC negative side of the output. That's why when I plugged that cheap power supply into my computer it sent 65 volts AC from the 12v negative side through the ground of my computer and fried it.

When I received this one I was very reluctant to test it with my amplifier computer combination because I shouldn't afford another $850 repair bill. And when I measured AC volts from the DC negative to the ground pin on the power plug I was reading 44 volts...

kevin_a: I'm using these as a power supply for LED string lights, and thus far they are working great for me. A couple of suggestions if this is your application also. First, don't try to use a 6A power supply if you have a continuous draw of 6A from the lights. You're asking for trouble, through early failure of the power supply and/or possibly burning the power supply up. Especially considering that these are Chinese sourced, I would only recommend drawing 50 - 75% of what the power source is rated at, or 3 - 4.5A in this case. That way, you have a much better chance of only having to install these once, which is the goal, right? Second suggestion - if you're connecting multiple strings to a single power source, connect them in parallel rather than in series. That means, don't connect one string to the end of another string, but run wire from the power supply to each of the LED strips separately. That will shorten the delay you see when switching the lights on, and you should also see less dimming from one end of the strips to the other.

Regarding my second suggestion, I've seen different explanations for that delay you may notice when switching on LED...

Daniel: It is the right connector for my led light strip.
