What this does and why you need it Connect up to four 3pin Addressable RGB (ARGB) devices from a single 5V ARGB header. Ideal when your motherboard has too few ARGB ports—no extra hub required. Keeps lighting synchronized and stable across fans, watercooling radiators, and case LED strips, eliminating flicker and desynchronisation caused by weak or noisy connections. Key benefits Effortless expansion: 1to4 3pin ARGB splitter lets one motherboard ARGB header control up to four ARGB devices simultaneously. Reliable signal and power: pure copper core wiring and 5Vrated design ensure stable current and signal transmission under load, reducing LED flicker and sync errors. Easy, plugandplay compatibility: matches standard 3pin ARGB header pinout for immediate operation with Addressable RGB motherboards from major vendors, including ASUS, MSI, and GIGABYTE. Flexible routing: segmented cable lengths and a flexible PVC outer jacket make it simple to route and store cables inside different chassis layouts without kinking. Technical details Connector: 3pin 5V ARGB (1to4 splitter) Maximum devices: 4 ARGB components (fans, radiators, LED strips, etc.) Cable layout: 25 cm main lead + three 10 cm branch leads Wiring: pure copper core for stable signal and current Jacket: flexible PVC for easy bending and clean cable management Practical use scenarios Build with limited ARGB headers: Connect four ARGB fans on the front or of a case to a single motherboard header to achieve a synced lighting profile without buying an external controller. Watercooling setup: Power and sync RGB radiator fans and a pump/LED strip from one ARGB header to maintain uniform color effects across the loop. Compact or budget builds: Route a case LED strip and multiple fans in a small chassis where motherboard ARGB ports are scarce, keeping cables tidy and eliminating the need for extra hubs. Why it stands out Designed specifically to match 3pin ARGB headers and deliver stable 5V operation. Cable lengths and flexible PVC jacket simplify installation in a wide range of chassis layouts. Pure copper wiring offers dependable performance under sustained load for consistent lighting. Compatibility note: Designed for standard 3pin, 5V Addressable RGB headers commonly used on ASUS, MSI, and GIGABYTE motherboards. Ensure your motherboard uses a 3pin 5V ARGB header before connecting.
