Hi all, I'm currently building a setup using 40 meters of ws2812b 5v pixel strip which has 60leds/m they draw roughly 14w/m. Now I've built a rack mount that houses two 60A power supplies plus network switch and pixlite controller. This is going to me mounted under a stage desk and the plan is to inject power every 2 meters into the installation. I have 4 lines going out to the strip and then 20 power injection points. Now the cables I've ordered from ray wu (and received) are 3 meter 2 core cables with waterproof connectors which look to be about 1.5mm2. Now I'm freaking out that these cables aren't going to be sufficient enough to power the lighting display and I've just prewired the whole rack mount with 2 pin plugs and don't have enough time before next Saturday to re-wire everything! I need some assistance in the best way to calculate where I currently stand with power consumption I'm a bit lost and with the size of this rig it's the first time I've had to worry about cable sizing. Any info is greatly appreciated! Thanks.
