1) This adapter only works with 3-pin 5V Addressable RGB connectors. It does not work with 4-pin 12V analog RGB connectors. Your motherboard must have the correct connector (For ADD_HEADER on Asus, For JRAINBOW on MSI, For D_LED on Gigabyte); make sure that you check your motherboard's manual before purchasing. This will work with all for Asus, for MSI, and for AsRock motherboards with the addressable header and most for Gigabyte motherboards (post z370 series). The connector should have 4 positions and 3 pins. 2) To connect for Corsair fans to your motherboard, you'll still need an RGB Fan LED Hub and an RGB Fan LED Hub cable.
Alternatively, you can also for Corsair Lighting Channel to Fan Adapters to connect 2 fans directly. 3) This works directly with(for HydroX) and (for Corsair) strips. You can connect these devices directly to the adapter to control them from your motherboard. 4) For Corsair SP-RGB fans cannot be controlled from the motherboard. They use a different protocol from the rest of the RGB LED fans and strips. This only applies to the older, original SP-RGB fans; the newer SP-PRO RGB fans can be controlled from the motherboard. 5) Do not attempt to plug this into a 12V, 4-pin connection.
Doing so and connecting to RGB items may damage the LEDs on the device. Note that this adapter does have one pin blocked to mitigate this issue.
