I've been bench testing 12V RGB lights for current, but I want to test ARGB lights now.
The 12V RGB is simply because it has a power connection and then the LED light connection only. That way I can test each channel (R G or B), or just put the power to all three and get total amps at 100% duty.
The ARGB, however, has 3 connections, power, negative, and data. How would I go about bench testing to check total amperage, which means all lights on 100%?

Hi, I guess one of the methods is to use a microcontroller to drive all the lights High and then measure the current using a multimeter/Ammeter.

ARGB is more of a marketing description - A stands for Addressable. What is the part number of the LEDs? I'd guess WS2812 or some such. Usually strings marketed as ARGB have a controller that drives them. If it's a bare string, then you will need to do what LexLabs said. The good news here is that once you ID the LEDs, there are plenty of libraries out there.

I may have to buy a 5V controller on amazon, cut the SATA power plug off, and then attach my power supply leads.

Thanks. I didn't know that. I assumed it meant Amber, Red, Green, Blue!

Or, in the spirit of truth in advertising, Almost RGB.
