Console Power Supply Reference
Look up the exact voltage, amperage, polarity, and connector type required for your retro console. Wrong PSUs can permanently destroy hardware.
DO NOT use a universal adapter without first verifying the correct polarity, voltage, and current rating. An incorrect voltage or reversed polarity can permanently destroy your console's internal components within seconds of powering on.
Center Positive vs Center Negative — What Does It Mean?
Barrel connectors have two contacts: the outer ring and the center pin. "Center positive" (marked ⊕ in the middle of the symbol) means the inner pin carries the positive voltage. "Center negative" (⊖ in the middle) means the inner pin is ground and the outer ring carries positive voltage. Connecting the wrong polarity — even at the correct voltage — will immediately damage most consoles, as internal protection circuits were rarely included in vintage hardware.
Why AC vs DC Matters
Most power adapters output DC (direct current), but a small number of consoles (notably the original SNES in North America and the original Genesis) require AC (alternating current). Using a DC adapter on an AC console, or vice versa, can damage the console's internal power regulation circuitry. Always check whether the required supply is AC or DC before plugging anything in.
If you are unsure, use a multimeter to check your adapter's output before connecting it to any console. Original OEM power supplies are always the safest choice if they are still available.
