AC/DC Adapter

Model JSY-1230

Input AC 100-240V

50/60hz

Output 12v=3A

12V times 3Amps = 36Watts...

I'm sorry if im posting this in wrong place but i need help with something.

A while ago i bought a 5m led strip 12/DC and i don't know is it safe to use 72 watts power supply

What voltage is the power supply? 72W only tells you the maximum power that supply can deliver, not the voltage it delivers it at.

72 Watts divided by 12 Volts is 6 Amps.

What kind of led-strip is it? Depending on type it might be tight, but it looks like its powerful enough.

Since most led-strips max out at 1A per meter on 12V

What @Hackentosher is saying we need more info to correctly asses that!

When i ask for more specs, don't expect me to know the answer!

it may or may not be depending upon the voltage that it outputs at.

Ok thanks a lot, i never worked with led strips and I don't know much about these things

Another thing we don't know is how much current (and thus power) the strip is expecting. A couple amps is probably fine, but beefy LEDs can pull tens of amps.

 

Practically speaking, I don't think I've seen a 5m LED strip pull more than about 2A (24W at 12v) so you're probably fine.

Wattage just means the psu can handle up to that amount of power draw at it's rated voltage. So without knowing the output voltage wattage is useless. Now it's a 12v 3a one which is only half of 72w but either way good enough for a 5m led strip unless it's one of those super dense ones. What kinda led strip did you buy? Got a listing off it? There are a couple types and usually a 4 digit code that describe the led setup on the strip.

Just FYI Standard (60leds per meter) 5050 RGB Ledstrips are about 1A per meter.

So with that 3A 12V supply 3 meters will be fine.
