Eclipse G400A
Spacious D-RGB Gaming Chassis
The G400A is the upgraded successor to the popular P400A, featuring a completely redesigned and more spacious chassis. It’s perfect for clean, modern hardware setups, easily accommodating even the largest graphics cards while leaving ample room for cable management. With up to 10 fan mounting points, support for 140 mm fans, and dedicated radiator space at the top, cooling performance has been significantly enhanced.
The G400A also supports the latest mainboards, with rear side connectors hidden to enable a cable-free appearance. Additionally, the graphics card benefits from direct cooling via three 120mm fan mounts on the mid-plate.

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