Will 1 24v laptop pwm be enough for 72 led's?

Probably not but it depends on the wattage of the power supply, how many watts or amps is it rated for?

For 72 LEDs you'll need at least 200W which I believe is much more than the average laptop requires. You can buy other power supplies that run at 24V at much higher wattage than a laptop supply. I would go larger to the range of 300-350 W encase you ever wanted to add more LEDs.
