You can change RGB lighting on your Sirius Power PC through your motherboard's RGB app or a third-party program like SignalRGB. Sirius PCs use software control, not a case button. This guide covers every method, plus how to turn lighting off completely. Every RGB component in a Sirius Power PC — case fans, RAM, and the motherboard itself — connects to the motherboard. That single connection point is why one app can control your entire system's lighting.
Sirius Power PC controls RGB lighting entirely through the motherboard manufacturer’s dedicated app. Some PCs use a physical case button or reset-style switch for lighting control. Sirius builds do not use this method — every system ships with software control instead.
The app you need depends on your motherboard brand. The next section shows you how to find it and use it.
Armoury Crate controls RGB lighting on ASUS motherboards, graphics cards, and compatible peripherals. Open Armoury Crate, select Aura Sync from the sidebar, then choose a device to customize its color, effect, and brightness. Aura Sync lets you apply one effect across every connected ASUS component at once.
Mystic Light is the RGB module inside MSI Center. Open MSI Center, go to the Mystic Light tab, and select a device from the list. Choose a lighting effect, set the color, and apply it. MSI Center also lets you sync lighting across all detected MSI components from one screen.
RGB Fusion 2.0 controls lighting on Gigabyte motherboards and compatible components. Open RGB Fusion, select a zone or device, then pick a color and effect from the panel. Gigabyte's app groups zones by physical location on the board, so you can light different areas differently.
Polychrome RGB manages lighting on ASRock motherboards and supports add-in cards. Open the app, select a connected device, and choose from its built-in effect list. Polychrome RGB syncs across ASRock-branded components automatically once each device is detected.
If you know what specific problem your PC is having — no power, no display signal, or crashing during a game — find it below for a more exact fix.
SignalRGB controls RGB lighting across mixed-brand components from one app. It works when your system combines parts from different manufacturers — for example, an ASUS motherboard with Corsair RAM or a Gigabyte graphics card — that don’t sync through a single vendor app.
Download SignalRGB from its official website, install it, and let it scan your system. Confirmed devices appear in a layout you can arrange to match your case. Select a device, choose an effect, and apply it the same way you would in a motherboard app.
