Hello,

I'm using MSI MPG X570 Pro Carbon WIFI motherboard. I bought a 5V adressable led strip from internet, the length of it is 150cm. It has 90 leds on the strip. I put the led in JRAINBOW socket but it didn't worked.

After I read the user manual of motherboard, it says that " IMPORTANT : The JRAINBOW connector supports up to 72 LEDs WS2812B Individually adressable RGB Led strips (5V/ Data/Ground) with the maximum power rating of 3A(5V)." The led strips chip is WS2812B so it is compitable with my motherboard.

Can I cut the led strip and decrease the led number to 70 or 71 ? If I can cut the led strip, will it work ?

I searched this on internet and find another MSI X570's user manual guide, and it says that ;

" IMPORTANT : The JRAINBOW connector supports up to 75 LEDs WS2812B Individually AddressableyRGB LED strips (5V/Data/Ground) with the maximum power rating of 3A (5V). In thecase of 20% brightness, the connector supports up to 200 LEDs."

What do I have to do ? Im so confused.
