Sirlyr RGB 12VHPWR Cable Set - ARGB PSU Extension with 24pin

In this review the Sirlyr RGB 12VHPWR Cable Set is judged as a targeted upgrade for PC builders who want vivid lighting and cleaner cable routing without replacing a power supply. The biggest reason to buy is the combination of bright, daisy-chainable ARGB illumination and a practical 16-pin to 3x8-pin 12VHPWR extension that lets owners of high-end GPUs connect using existing 8-pin PSU cables. Installation and flexibility are emphasized throughout, making it a smart cosmetic and functional mod for modern desktop builds.

Key Features

• Vibrant RGB lighting: 24pin ATX cable includes many LEDs and the 12VHPWR cable includes a high LED count for rich, customizable colors that integrate with motherboard ARGB software.
• 12VHPWR GPU extension: The 16-pin male to 3x8-pin female design lets users connect RTX 40-series cards using existing 8-pin PSU cables without upgrading to an ATX 3.0 power supply.
• Flexible construction: Patented LED strips, silicone tubes and soft PVC sleeving improve bendability and make routing easier inside tight cases.
• Easy to install: Plug-and-play ARGB connectors can daisy chain through a 5V header or use the included SATA-powered controller when motherboard headers are limited.
• Stable wiring: 16AWG wire core is used for the power conductors to support stable performance during gaming and heavy loads.

Who It's For

The Sirlyr set is best for PC enthusiasts building a showcase desktop who need both visual upgrades and practical cable length solutions for RTX 40-series cards like the 4090 or 4080. It suits builders who want ARGB synchronization with motherboard software or a simple SATA-powered controller for additional LED capacity.

Less suitable are users who require a native ATX 3.0 12VHPWR PSU solution for factory 12VHPWR cables or those who need fully sleeved, solid-core modular cables for extreme overcurrent customization; this product is an extension set focused on lighting and routing rather than replacing every factory cable.

Pros & Cons

Pros

• Bright and customizable ARGB lighting that syncs with motherboard software or runs from the included controller.
• Practical 16-pin to 3x8-pin 12VHPWR extension removes the need to upgrade the power supply for many high-end GPUs.
• Flexible silicone and soft PVC construction makes cable management simpler in compact cases.
• Plug-and-play setup with daisy-chaining support for additional ARGB devices.

Cons

• Includes an adapter-style 16-pin to 3x8-pin connection rather than native ATX 3.0 wiring, which some users may prefer for future-proofing.

Frequently Asked Questions

Will this let me use my RTX 4090 without changing the PSU?
Yes, the 16-pin to 3x8-pin 12VHPWR extension is designed to work with existing 8-pin PSU cables so many users can avoid buying a new ATX 3.0 supply.

Can the ARGB lighting be controlled by motherboard software?
Yes, the cables support daisy-chaining to a 5V ARGB header for software control or can run from the included SATA-powered controller if the header cannot support enough LEDs.

Is the cable flexible enough for compact cases?
The combination of silicone tubes, patented LED strips and soft PVC sleeving improves flexibility and routing in limited case space.
