| Jul 27, 2018 at 5:05 | comment | added | piojo | @Picard102 Somehow I managed to ignore the controller. The other comments are correct, you cannot put them in series and assume they will share voltage equally if the controllers are doing something different. Better not try it. | |

Because these have built in control, they likely must operate as a parallel arrangement. The variety of power supplies that will work for you is truly massive. If the 8A supply on Aliexpress lives up to it's rating, there is a chance it would be adequate for the full set, you really would have to measure under full load to be sure. If it is a switched mode DC power supply, it is likely designed to have max efficiency close to max load. | |

| Jul 27, 2018 at 3:53 | comment | added | Glenn Willen | You definitely must not connect them in series. If you do that, and then e.g. dim one of the strips while leaving the others bright, the voltage across the dimmed strip will rise above 12V and potentially destroy it. (That's assuming you use multiple controllers -- if you try to do this with a single controller for multiple strips, you will short out the power supply.) | |
| Jul 27, 2018 at 3:26 | comment | added | Picard102 | I think I have to plug the power into the controller, which then powers the LED's. How would I connect them in a series if that's the case? A spliter like this? goo.gl/tNLVFo | |
