ARGB LED Ring Singularity Computers Protium 3.0 ARGB Ring Acetal — 6× ARGB LEDs 5V, 500mm cable

The Singularity Computers Protium 3.0 ARGB Ring in acetal is a compact, purpose-built lighting accessory for custom PC builds and liquid-cooling loops. It houses six individually addressable ARGB LEDs running at 5V and is supplied with a 500 mm cable for connection to a compatible 5V ARGB header or controller. The ring's acetal construction offers a durable, low-reflective finish suitable for subtle or accent lighting in case interiors, reservoir tops, or tubing mounts.

Advantages

The Protium 3.0 ARGB Ring provides individually addressable LEDs that enable precise color placement and dynamic lighting effects when paired with motherboard software or an ARGB controller. Its acetal body resists visible wear and minimizes unwanted reflections, helping directional lighting appear crisp and consistent. The included 500 mm cable simplifies routing inside a case and supports standard 5V ARGB connectivity for straightforward integration into existing lighting ecosystems.

Suitable for

• Accent lighting inside PC cases to highlight components or cable runs
• Illuminating reservoir tops or fittings in custom liquid-cooling loops
• Adding programmable ARGB effects to compact or constrained spaces
• Use in builds where controllable, addressable point lighting is required

When it may not be suitable

The ARGB ring requires a compatible 5V addressable RGB header or a dedicated ARGB controller to access individual LED control and dynamic effects; it will not produce addressable effects when connected to a non-addressable 12V RGB header. With only six LEDs, it is intended for accent or localized illumination rather than broad-area backlighting. The form factor and mounting options are specific to certain placements and may not fit all custom layouts without additional brackets or modifications.

Key specifications

• LED type: Individually addressable ARGB LEDs
• Number of LEDs: 6
• Operating voltage: 5V
• Cable length: 500 mm
• Material: Acetal body
• Intended use: Internal PC case and liquid-cooling lighting

How to use

Mount the ARGB ring in the chosen location inside the case or on a reservoir, ensuring it is secured and oriented for the desired lighting effect. Connect the 500 mm cable to a 5V addressable RGB header on the motherboard or to an ARGB controller, observing correct pin orientation. Use the motherboard lighting software or controller interface to assign colors, set animations, and synchronize effects with other addressable devices. Route the cable neatly to avoid contact with fans, tubing, or moving parts.

What to consider before purchase

• Presence of a 5V addressable RGB header or compatible ARGB controller in your system
• Available space and mounting options where the ring will be installed
• Desired lighting coverage—six LEDs provide localized accent lighting rather than full-area illumination
• Cable routing needs and whether the 500 mm length is sufficient for connection

Usage recommendations

For best results, integrate the ring with your motherboard's ARGB software to create coordinated effects with other addressable components. Position the ring close to the area you want to highlight and use its directional output for rim or accent lighting rather than as a primary light source.
