Hi guys I've been playing around with my lights and i'm hitting problems with Powering a few hundred pixels. at the moment I've got a 220w PSU from an old PC with a bit of tire wire (about and inch long) running from alligator clipped to a bit of old thick car amplifier wire(approx 5mm) clipped to a banana plug wallplate directly to a string of 100 ws2811 pixels form ray wu this draws 5.55 amp when all pixels are on white and runs fine . but when i double the pixel load same setup just two strings of 100 at the banana plugs. ( the ground wire is all 0.12mm). My question is with that amp draw of just 2 strings how do I power a few hundred lights ( with out risking fire and move that much amp draw from the garage to the front yard and around (approx 20m - 30m. i feel like I'm missing something, any help would be appreciated. also what power supply is suitable or should use a few PC PSU?
