Powering LEDs

Post by foxtrot150504 »

Q: How can/should I power my LEDs?

Info: I am using 3m of adafruits 144 LED strips and 4m of the 60 LED strips.

144 LEDs https://www.adafruit.com/products/1507
60 LEDs https://www.adafruit.com/products/1138
My Power Supply http://www.newegg.com/Product/Product.a ... 6817151110
Micro Controller http://www.newegg.com/Product/Product.a ... 0002-00003

I would love if I could somehow use my computers power supply to help power these lights, however I doubt this is possible with the amount of wattage/amps these guys will pull since I am using so much. So should I pick up a dedicated power supply? If so from where?

If you can dedicate the ATX power supply to the LEDs, you could run some of the LEDs on the 5V output, and the rest on the 3.3V output. Otherwise, you would need two of those ATX supplies to run all of the LEDs at 5V, as you need about 40A at 5V.
