The safest way to label retro console cables and power adapters is to identify what each item belongs to, what it does, what connects at the other end, and where it should be stored. Put matching labels on both ends of signal cables. Give power adapters a more detailed tag copied from verified manufacturer information, but never treat your new label as proof that an adapter is electrically compatible.
This matters once a collection grows beyond one console and one television. A yellow RCA plug might carry composite video, but an RCA connector can also carry component video, analog audio, or another signal. SCART describes a connector, not a guarantee that the cable carries RGB. A plug that physically fits is therefore only the beginning of the compatibility question. Planning the complete multi-console connection path first makes the labels much more useful.
Build the identification system before printing labels
Start with an inventory rather than a sheet of vague names such as “Nintendo,” “AV cable,” and “power.” Those descriptions feel adequate while the equipment is spread across the floor. Six months later, they leave you comparing nearly identical plugs under a desk.
Create one record for each console and accessory. At minimum, note the console family, exact model or revision when known, region, cable purpose, signal type, connector at each end, and normal storage location. If the system has been modified, record the modification because it may change which output or cable is appropriate. These are also the details worth documenting when planning a shared display setup.
| Field | Useful example | Why it belongs |
|---|---|---|
| Console and model | Genesis Model 2 | Separates hardware revisions that may use different connections |
| Cable purpose | Video to scaler | Explains the cable’s job rather than merely its appearance |
| Endpoints | Console AV out → SCART switch input 3 | Makes both ends of the route identifiable |
| Signal | RGB with stereo audio | Prevents connector shape from standing in for signal type |
| Storage code | Bin B2 | Provides a destination when the cable is disconnected |
| Status note | For modified console only | Flags an exception that could otherwise cause a mismatch |
Use a short, stable console code if space is tight. “GEN2” can mean Genesis Model 2, while “SNES-NA” can distinguish a North American SNES from another regional unit. Keep a simple key on the inside of the storage cabinet or in your setup notes. The code should reduce label size without forcing you to decipher an elaborate private language.
Label both ends of every signal cable
A label beside the console tells you what you are unplugging. A matching label at the display, switch, receiver, or scaler tells you what you are about to reroute. Labeling only one end solves half the problem, which is usually the half currently hidden behind furniture.
Use the same primary identifier at both ends, then add endpoint-specific text. For example, the console end could read “SNES-NA / AV OUT,” while the other end reads “SNES-NA / S-VIDEO SWITCH 2.” If you later move that cable to another input, replace or update the endpoint label instead of leaving obsolete routing information in place.
Include the signal where confusion is possible. “PS2 / COMPONENT YPbPr” is more informative than “PS2 VIDEO,” especially near a switch full of RCA plugs. If you need to verify the distinction before labeling, this guide to composite, S-Video, component, and RGB signals explains why the connector and the signal must be treated separately.
Treat power-adapter labels as references, not approvals
Power adapters deserve their own label format because the consequences of a mismatch can be worse than a missing picture. Record the exact console model and region first. Then copy the original adapter model number and its marked electrical information accurately: input, output voltage, whether the output is AC or DC, rated current, and polarity when a DC polarity symbol is actually present.
Do not infer a polarity symbol from the barrel connector. The RetroTechCollection NES maintenance reference documents the North American NES-002 adapter as accepting 120V AC at 60Hz and 17W, then supplying 9V AC at 1.3A for NES-001 and NES-101 systems. Because that output is AC, assigning it a DC center-positive or center-negative polarity would create false information.
Likewise, a family resemblance between systems is not a compatibility standard. The Sega Genesis Model 2 instruction manual directs owners to use the adapter supplied with the system and warns against substituting another adapter. It also specifically says not to interchange Genesis and Sega CD adapters because each is intended for its respective device.
A sensible adapter tag might read “GENESIS MODEL 2 / ORIGINAL ADAPTER: MK-2103 / VERIFY AGAINST FACTORY PLATE.” The exact model and ratings must come from the adapter, console manual, or another reliable reference for that hardware. If the factory printing is faded or the adapter’s identity is uncertain, mark it “UNVERIFIED—DO NOT USE” and keep it out of the active cable bin until it can be identified.
Use a label layout that stays readable
A compact label should present information in a consistent order. Put the item identity on the first line, purpose or endpoint on the second, and storage or caution information on the third. Keeping the same hierarchy across the collection makes the tag readable without requiring every label to use the same dimensions.
- Cable end: SNES-NA / CONSOLE AV OUT / S-VIDEO
- Display end: SNES-NA / S-VIDEO SWITCH 2 / BIN B2
- Power tag: GENESIS MODEL 2 / ADAPTER MODEL AND VERIFIED OUTPUT / BIN P1
- Uncertain item: UNKNOWN ADAPTER / NOT VERIFIED / QUARANTINE BIN
Color can provide a secondary cue: blue for video, green for audio, red for power, and gray for controllers or data. Do not make color the only identifier. Low light, faded printing, color-vision differences, and a bin full of similar tags can all defeat a color-only system. Text remains the authority.
Plan a mixed sticker sheet around repeated label types
A mixed sheet is useful because a cable setup needs several shapes rather than dozens of identical stickers. Allocate narrow paired labels for cable ends, larger tags for adapters, and a few bin or switch labels. Add blank versions of each design for equipment you acquire later.
YouStickers lists kiss-cut sticker sheets that can combine different designs, sizes, and shapes. Its listed standard sheets range from 6 × 4 to 11 × 8.5 inches, with custom dimensions also available, and the minimum listed quantity begins at five sheets. The product information says artwork can be submitted in PNG, JPG, PDF, AI, or SVG format, after which cutlines and layout are prepared for a proof. For custom sticker printing and sticker-sheet options from YouStickers, see details.
Design conservatively rather than packing every gap. The product guidance recommends approximately one-eighth inch of bleed, keeping text roughly one-eighth inch inside the cut, and leaving room between cutlines. The company’s general FAQ gives a more conservative planning figure of 0.25 inch between designs and states that individual stickers must be at least 0.75 inch. Use the stricter spacing while preparing the sheet, then confirm the final cut layout in the proof.
Avoid ordering around an assumed price. The inspected configurator did not provide a price without a specific size, quantity, and configuration. Build the actual sheet, choose the finish and quantity, and evaluate the resulting total rather than relying on an unconfigured headline figure.
Store the system so the labels remain true
Labels fail when the storage routine contradicts them. Give each console family a bin, drawer, or hook code and return every disconnected item to that location. Keep questionable adapters in a separate quarantine bin, not beside verified power supplies. If a cable changes jobs permanently, update both endpoint labels and the inventory at the same time.
The finished system should let you trace a connection without guessing: console model, cable function, signal, destination, and storage location. For power, it should also preserve the verified adapter identity and ratings while leaving the original safety information visible. That is the useful balance—fast setup without turning a fresh sticker into false confidence.
