How to Install RGB Lighting: Step-by-Step

Quick Answer

Installing RGB lighting in a PC is straightforward if you plan power, headers, and routing first. Mount strips inside the case with adhesive or magnetic clips, connect to ARGB or RGB headers on your motherboard, then sync everything through one control app for clean, unified colour.

What You Need Before You Start RGB Installation

Before opening the case, gather your kit and confirm compatibility. You'll want ARGB strips (5V three-pin) or older RGB strips (12V four-pin), a motherboard with matching headers, an ARGB hub or splitter if you're chaining multiple devices, cable ties, isopropyl alcohol wipes, and a small Phillips screwdriver. Most modern boards from ASUS, MSI, Gigabyte, and ASRock sold locally include at least one ARGB header, but older B450 or H310 boards sometimes only ship with the legacy 12V variant. Check your board manual rather than guessing, because plugging a 5V strip into a 12V header will fry the LEDs instantly.

If your case fans are already RGB, like Corsair iCUE or Lian Li UNI Fans, you'll route those through their proprietary controller instead of the board. Plan the path of every cable before mounting anything. Loadshedding is a real factor here too: any time the wall power flickers your strips reset to default colours, so keep the controller's profile saved to non-volatile memory and ideally run your build on a UPS to protect the components during the install bench tests.

Step-by-Step RGB Lighting Installation

Start by powering down the PC, switching off the PSU at the back, and removing both side panels. Wipe the mounting surface inside the case with an isopropyl pad so the adhesive grips properly, especially on textured steel. Peel a short section of the strip's backing tape, press it against the top edge of the case interior, then work along slowly to keep the run straight. For corners, use the included 90-degree connectors rather than bending the strip itself, which damages the LEDs.

Next, plug the strip's three-pin (or four-pin) connector into the matching ARGB or RGB header on the motherboard. Mind the arrow on the cable: it must align with the +5V pin on the board. If you're running multiple strips, daisy-chain them or use an ARGB splitter so they all read as one device. Tuck spare cable behind the motherboard tray and secure with cable ties. Reconnect the side panels, switch the PSU back on, and boot the system. The LEDs should light up immediately in default rainbow.

Configuring Software and Syncing Your RGB Ecosystem

Software is where most builders trip up. Each motherboard brand has its own utility: ASUS Aura, MSI Mystic Light, Gigabyte RGB Fusion, or ASRock Polychrome. Install only the one matching your board, because running two RGB controllers at once causes flickering and address conflicts. Open the app, detect your devices, and assign a static colour or effect across the chain. If you've added Corsair, Cooler Master, or NZXT peripherals, you'll layer their proprietary apps on top. OpenRGB is a great free alternative on local SA builds when you want to control everything from one tool without bloatware.

Save the profile to the controller's onboard memory wherever the option exists. That way, the colours hold through a cold boot, a CMOS reset, or a sudden power cut. For builders running 240Hz panels and high-end Ryzen 7 or Core i7 systems, the small CPU overhead from RGB software is negligible, but disable startup launching if you want every millisecond back.

Troubleshooting Common RGB Installation Issues

If a strip stays dark, the most common cause is a reversed connector. Pull it, flip it 180 degrees, and reseat. If only half the strip lights up, you've likely cut between the wrong pads or damaged a chip during install. ARGB strips can only be cut at the marked scissor lines. Flickering across the whole chain usually means the 5V rail is overloaded; spread the strips across two headers or add a powered ARGB hub. Mismatched colours between fans and strips often come from running both Aura and iCUE simultaneously, so pick one master controller and let the other run in passive mode.

Frequently Asked Questions

Can I install RGB lighting in any PC case?

Almost any modern case works as long as you have somewhere to anchor the strip and a path back to the motherboard. Tempered-glass cases shipped by Evetech come with cable management cutouts that make routing painless. Older OEM cases without a cutout still accept stick-on strips but cable hiding takes longer.

How much does an RGB upgrade cost in South Africa?

A basic ARGB strip kit lands around R250 to R450 at evetech.co.za, an ARGB hub adds roughly R350, and a full set of three RGB fans sits between R900 and R1,800 depending on brand. NSFAS-budget builders can light a case for under R600 with a single strip and a splitter, with same-day Joburg or Cape Town delivery if ordered before the cutoff.

Do RGB lights affect gaming performance?

The LEDs themselves draw under 5 watts total and have zero impact on frame rates. The only measurable hit comes from the control software running in the background, and even that is well under one percent CPU load on a modern Ryzen or Core i5 build.
