[TriEmbed] TriEmbed Digest, Vol 20, Issue 45

[Adam Haile]

Chip,
It depends on the pixel density. But the general rule is allow for 60mA per
LED (20mA per color) at full white. So, for a 5m roll of 32 LEDs/meter
that's 160 LEDs or a possible 9.6A draw. It's unlikely it will ever hit
this but I *always *allow for max draw plus 10-20%.

MPJA.com sells some very cheap, high amperage supplies:
http://www.mpja.com/5-Volt-Power-Supply/products/534/
I bought 8 of these (25A @ 5V for $5!):

You can also find decent ones on Amazon:

Wow... long link.

I generally like to keep around at least a 20A supply for playing around.
Then I can handle 2 rolls no problem.
