SATA-Powered 5V ARGB Hub Controller

Physical specs: 46 × 22 × 9.5 mm (1.81 × 0.87 × 0.35 inches), constructed from high-grade ABS plastic for structural integrity and long-term reliability. Electrical interface: accepts standard 5V 3-pin ARGB input signal and draws power via SATA 15-pin connector — no 3-pin header or USB power required. Cable tolerances: 3-pin signal cable is 170 ± 10 mm; SATA power cable is 500 ± 10 mm. Functions as a standalone PWM-based ARGB repeater/hub — does not require motherboard support or third-party lighting software. Three dedicated buttons enable full local control: 'M' cycles through pre-programmed lighting effects; 'S' adjusts transition speed across 8 steps, and a 4-second hold powers the entire ARGB chain on/off; 'C' changes hue or reverses flow per mode, and a 5-second hold steps through 6 brightness levels. Compatible with all mainstream 5V 3-pin ARGB components — case fans, light strips, pump tops, radiator fans, and front panel lighting modules. Designed for UK/EU builders prioritising simplicity and compatibility — especially valuable when upgrading legacy systems, using non-RGB motherboards, or adding more ARGB devices than the motherboard can natively handle. Eliminates reliance on inconsistent BIOS implementations or vendor-locked apps that often fail after Windows updates.
