Guibi1 Posted February 3, 2020 Share Posted February 3, 2020 Hi everyone, i bought WS2812b from amazon to make my own strips, puting them outside of my case, and saving some money... (dont say it too loud) My setup works well, until i add a second strip on the other channel of my CLNP. Here’s the link to the video showing me connecting the second rgb strip... https://drive.google.com/file/d/1vPUyKYTMvigC2jHZ0Am37IlUVD-Hws8M/view?usp=drivesdk Knowing that i cut off the sata cable and only connected the 5v to my PSU, do someone out there could know why that’s happening? (each strip works on each channel individually) Here is the link to the strips, if it helps: https://www.amazon.ca/dp/B01LSF4Q0A/ref=cm_sw_em_r_mt_dp_U_5IioEbHXK279H Here is a link the the thread i followed to make the strips: https://forum.corsair.com/v3/showthread.php?t=168504 Link to comment Share on other sites More sharing options...
DevBiker Posted February 4, 2020 Share Posted February 4, 2020 Are you using SIV as well? And 144 LEDs on each channel? Link to comment Share on other sites More sharing options...

Put a ground from the strip to the power supply like you did with 5v. You can't rely on the ground of the USB to support that. You're going to potentially kill the LNP and possibly even the USB controller. It also wouldn't be a bad idea to have a capacitor between the 5v and ground close to the beginning of the RGB strip.

Guibi1 Posted February 6, 2020 Author Share Posted February 6, 2020 Im only using iCue, and im working with 60 leds strips. I will try to ground my CLNP soon... Link to comment Share on other sites More sharing options...
DevBiker Posted February 6, 2020 Share Posted February 6, 2020 also, what's the amperage/current supported for that power supply? Link to comment Share on other sites More sharing options...
Guibi1 Posted February 6, 2020 Author Share Posted February 6, 2020 its connected to my 750w psu, shouldnt be a problem... Link to comment Share on other sites More sharing options...

You can ground both the LNP and the strip. Even with 60 LEDs you're risking damaging your system. You shouldn't use it until you properly ground it.

Guibi1 Posted February 6, 2020 Author Share Posted February 6, 2020 How does that make any difference ? My strips are connected directly to my psu. That or an external psu shouldnt change a thing. Link to comment Share on other sites More sharing options...

Guibi1 Posted February 9, 2020 Author Share Posted February 9, 2020 Thanks alot guys. I connected my CLNP's ground to my PSU and now it works perfectly! I still dont know why i should put a capacitor, and which one i should put. Isn't there already capacitors within the strip ? Link to comment Share on other sites More sharing options...
