Sirlyr RGB 8-Pin PCIe Cable – 360° ARGB GPU Extension for RTX 3060/4060/4070 and RX 6600/580 | Black

Upgrade your PC's aura with Sirlyr's RGB 8-pin PCIe Cable. This kit blends a GPU power extension with a built-in LED strip, featuring 27 LEDs that deliver a smooth, 360-degree glow along the full length of the cable. The result is a luminous accent that adds depth to a blacked-out build. The black exterior, discreet connectors, and slim light strip create a visually cohesive look that complements glass side panels and dark chassis aesthetics without overpowering other components.

Designed for both aesthetics and reliability, the cable uses flexible silicone insulation to ease routing around tight corners, while silver-plated cores help maintain stable current during demanding gaming sessions. This combination supports a clean, organized wiring layout while keeping the lighting vibrant and steady under load. The overall design aims to deliver a polished finish to cases that emphasize sleek, professional tones.

Design and lighting highlights

• Integrated PSU extension with a 27-LED lighting strip for 360-degree brightness
• Black 8-pin GPU extension that harmonizes with dark chassis and glass panels
• Flexible silicone construction for easy bending and routing
• Silver-plated conductors to help maintain stable current during intense use

Setup and compatibility

The cable daisy-chains with motherboard 3-pin ARGB headers or other 5V3-pin ARGB devices. When paired with motherboard RGB SYNC software, you can tailor lighting to match your system. If ARGB support is unavailable on the motherboard, the included mini RGB controller provides independent lighting control.

• Daisy-chain with ARGB devices for synchronized effects
• Motherboard RGB SYNC compatibility for cohesive color schemes
• Mini RGB controller powered by SATA for standalone lighting control

What you get in the kit is straightforward and ready to install: one black 8-pin GPU cable, a mini RGB controller, and a concise instruction manual. The result is a visually striking upgrade that blends aesthetics with practical cable management for a neater build.

Upgrade your rig with Sirlyr s RGB power extension and enjoy a lighting setup that enhances your gaming or listening sessions without promising guaranteed results.
