Will a 12v automotive power supply be sufficient power for this? Looking to run 4 strips for a total of 64 ft of led.

Yes just make sure that you get 12v dc LEDs and think you need mor then one repeter each strip is 16 feet long and can draw 72 watts at 12v each

You can't run them in series. Parallel only. Run a set of wires from the power source to the start of each strip. Incidentally, a couple things about that power supply...It's not as pictured (at least in my case) It has a noisy fan. I returned it and used a re-purposed computer power supply. Also, this power supply will not run 4 strips. If I remember correctly these strips run 72 watts each which is about 6A at 12 volts. 6X4 = 24A required. And with the distances you are talking about, you're going to need a bit more than minimum.

Yes, but the unit will only control 11watts worth of LED strips. Also you have to figure that load on your supply. Doing the math you can drive around 9A with this controller. But that is at almost 100% of it rating and that is not advised. I would only run it at 50-60% of it rating. So 5-6A Now you just need to find out how many Amps or watts each string draws.

I would say that as long as the controller supports the 24v input, then the strips will work. While I'm sure that others LED strips have tight tolerances, I've found that these can work with most anything you give them. These are essentially a row of LEDs that just have the power level ajusted per color. I just tested having two strips run off one controller (given, mine is a 12v 6a) and they work just fine. The white at full brightness is a bit 'dirty' because there isn't enough power, but otherwise it works.

Here is a link to the most extensive testing I've seen with these lights (although the link is discussing the 300 LED version, so you'll want to do your own calculations based on these numbers.) Basically the spec sheet states .24 watts per LED. Of course you'll have to take into account the voltage drop, and with 20M of them you'll definitely want to look into dual-feeding to keep consistent brightness/color value... but all of that is explained in the link below much better than I can do here. Hope that helps! http://electronics.stackexchange.com/questions/19413/why-doesnt-my-5050-led-strip-draw-as-much-power-as-i-expect

Are you running 3 full standard 16.4ft, 150 led rolls/strips equaling 49.2 feet? Each strip is 3 Amps witch means the power supply must be 12v 9 Amps minimum. If you are over 49.2 feet you might need a stronger power supply or add another amplifier to the run. The amplifier output reads 12A but I've noticed that all diagrams never show more the two strips per amplifier. Good luck

You can run quite a few off of one power supply. Led use almost no power to run. I have limited 4 16 ft strips to one. Box. I have used one y. And connected 2 strips to each side. If you buy the led strips fom 2 seperate vendors, the wires won't match up.

5amp at 12 volts is 60watts, slightly underrated. If you intend to use white at full intensity (or many of the other color combinations) you could pull close to the rated 72 watts each strip which is 6 amps. I would spend the extra money on a good properly rated power supply.

Yes these require 12v of power and they are tapped to an existing light source on the vehicle which you want the LED strips to turn on with.

These LED strips operate on 12VDC (see product description), therefore a proper power supply is required (such as B0034GUEY4).

It depends on 2 things. Your power supply is first. Each strip takes 72 watts. So your 12v supply has to put out 72 watts or 6 amps. The controller is rated at 6 amps. So therefore only 1 controller for each strip. However, I have used a 3 amp supply running 2 strips and it worked fine. My guess, if you used a 6 amp, 12 volt supply you could run 4 lines. Just remember, if you are trying to get white out of this, it uses all 3 colors (red, green, and blue) to get the effect of white. This is when you are using the full amount of power at 72 watts. If your supply can't handle the LED's then they will just run dimmer. As far as the controller, I have ran the 2 lines and it has not even got warm after 6 hours of use in the Palm Springs, CA area during a summer night. Which is about 85 degrees. My next test will be with a 6 amp supply and 4 lines with 1 controller. Since you get a controller for each line, if one goes out, no big deal, I'll just cut back to 2 lines.

Each strip requires 12VDC at 6amps. Do not daisy chain all 4 strips together. The strips can't handle 24 amps through the traces of 4 strips. You need to connect each strip separately to the power supply. You can use 4 separate 6amp power supplies or use one 30amp power supply. The data connectors need to be daisy chained together. You input the data to the first strip and it passes to the rest of the strips. The RGB LED's are in groups of 3 so 10 pixels per meter or 50 pixels per strip. 4 strips equals 200 pixels total. I hope this helps.

I just tested it, and it does work. However, keep in mind it will be extremely dim. Not only that, but in my case it was constantly flickering (however, this could have been due to lack of amperage). To be safe and sure, I'd go for at least a 12v 3a power supply. For my setup (11 strings total outside), I this for power: http://www.amazon.com/gp/product/B008HARHN8 Which I hooked up to http://www.amazon.com/gp/product/B00A46UAQO Using a single controller, with split outputs, for the colors.

The issue is voltage drop and current carrying capacity of the strip, not the power supply (although the power supply obviously needs to be big enough too). You could probably get away with a 20ft run as long as had sufficient current form the supply. I also would plan to only use a supply at 80% of its rated capacity. Most of the low cost ones you see here and other places are not really built to handle 100% duty cycle at their rated output. They'll kill themselves with heat buildup and other issues.

No...the led strip requires an RGB Driver (included). This driver input requires a 12VDC source but the input to the Driver requires a 2.1 m X 5.5 m center positive barrel connector, not included. This connector can be purchesed seperatrly, it will have the correct output connector and flying leads that can be connected to your 12VDC source.

Total power consumpion of LED strip is 75W, so 10A 12V DC Power supply is more than enough!

The included power supply provides 5 amps at 12 volts, each strip uses about 2.6 amps at full brightness, so connecting 3 strips will work, but they will become dimmer at the ends when you make them fully bright. To connect 3 strips to 1 single power supply you must buy one that can provide at least 7.8 amps at 12 volts, or your led strips will not be as bright as they could be.This power supply will power 3 LED strips:http://www.amazon.com/Power-Adapter-Prong-Output-3224-12V/dp/B0057KIHAI/This adapter will let you connect the controller in the middle instead of at one single end:Ledwholesalers 4 Pin Splitter for One to Two LED RGB Color Changing Strips, 2355Hope that helps! :) The included power supply provides 5 amps at 12 volts, each strip uses about 2.6 amps at full brightness, so connecting 3 strips will work, but they will become dimmer at the ends when you make them fully bright.
