FAQ

What is Digital-RGB?

Digital-RGB means that each LED chip can be controlled individually, allowing for multiple colors and effects in a single D-RGB LED strip. While regular RGB LED strips can only show the same color on each LED chip per strip at a time. However, not every Digital-RGB (Addressable) product is the same.

Phanteks D-RGB products

Are plug-and-play. No software is needed, yet it is compatible with software control through MSI or ASUS compatible motherboards if desired. Have custom developed color patterns. We believe D-RGB lighting can be stylish when having the right color/pattern settings, which is why the Phanteks D-RGB controller is pre-installed with custom selected color modes and patterns.

Have 30 LED chips. This is a lot! Having 30 LEDs per product instead of just 8 or 12 creates a much more beautiful color gradient and higher quality lighting. This also means more color tints can be displayed simultaneously in one strip.

Why are Digital-RGB and RGB not compatible?

Digital-RGB and RGB have a different connector. Digital-RGB uses a 3-pin connector while RGB uses a 4-pin connector. Technical explanation: Digital-RGB uses 5 Volts while RGB uses 12 Volts. Connecting Digital-RGB products and RGB products would cause damage.

Is Digital-RGB compatible with my mainboard?

Digital-RGB from Phanteks is compatible with Asus Addressable-equipped motherboards and MSI Mystic Light Rainbow-equipped motherboards. Check with the Motherboard specifications if your motherboard has a ‘AURA Addressable Header’ or a ‘Mystic Light Sync Rainbow header’ with 3 pins.

How many D-RGB products can I connect to a compatible mainboard?

Each D-RGB product uses 1 Ampere. Check the power output with your motherboards specifications to determine how many D-RGB products can be powered by your mainboards. Currently mainboards support 3 Amperes.

How many D-RGB products can I connect to the D-RGB controller from Phanteks?

The Phanteks D-RGB controller can support up to 7 D-RGB products when using the remote. If the D-RGB controller is connected to your motherboard a total of 9 D-RGB can be connected to the controller. A maximum of 4 D-RGB products can be connected to a single output port on the controller.

How do I connect my D-RGB product from Phanteks to my mainboard?

Most of the D-RGB products and compatible mainboards include a mainboard adapter. Simply connect this mainboard adapter to the Addressable or Rainbow port on your mainboard and the Phanteks D-RGB products. D-RGB products from Phanteks can be daisy-chained so you only need one port on your motherboard. Most mainboards also include this motherboard adapter cable.

Can I install multiple Digital-RGB controllers in my case?

You can install as many D-RGB controllers as you would like. However they do not connect to each other. Each controller will work, and need to be controlled, individually.

How do I turn off the D-RGB LED’s on the Phanteks D-RGB controller?

Press and hold the ‘Mode’ for 2 seconds until the LED’s turn off. When using software control please consult with the motherboard manufacturer.
