RGB & ARGB Case Lighting and LED Strips (5)
How to Choose Case Lighting
Good case lighting is about matching the strip to your header and the look you're after, then mounting it where it shows off the build instead of glaring at the glass. Work out whether you want addressable ARGB effects or simpler single-colour RGB, confirm the header on your board, and measure the run. The guide below covers the decisions that matter.
ARGB (addressable) controls each LED individually, so you get gradients, rainbows and chasing animations. Standard RGB lights the whole strip one colour at a time. ARGB uses a 3-pin 5V header; RGB uses a 4-pin 12V header. If you want modern dynamic effects, choose ARGB and make sure your board or controller supports it.
Most ARGB strips connect to a motherboard ARGB header and sync through the board's software — Aura Sync (ASUS), Mystic Light (MSI), RGB Fusion (Gigabyte) or Polychrome (ASRock). Check you have a free header of the right type. No compatible header? A dedicated ARGB controller or hub runs the lighting independently with its own remote or app.
Measure the runs inside your case — top edge, front edge and the bottom near the PSU shroud are common mounting lines. Magnetic or adhesive-backed strips follow these edges cleanly. Buy a length that covers the runs you want without forcing a tight bend, and check whether strips can be linked if you need to span more than one edge.
Aim the strip so it lights the components, not straight at the tempered-glass panel — pointing LEDs at the back of the panel or along an edge avoids hotspots and glare. Magnetic strips suit steel cases; adhesive ones work anywhere but plan placement first, as repositioning weakens the tape. Tuck the cable behind the motherboard tray for a tidy finish.
ARGB and RGB headers on the board are the simplest route and keep everything in one software ecosystem. If you're out of headers or your board has none, a controller or hub powered from SATA or a fan header adds capacity and a remote. Don't daisy-chain more strips onto a header than it's rated to drive, or colours can dim or flicker.
