4 Things to Know About the ASRock DeskMini B660's Power Supply

  1. The system uses a 120W (19V/6.32A) barrel connector power adapter. This external brick is the only way to power the DeskMini B660.

  2. The barrel connector design prevents standard power supply swaps. You cannot replace it with a standard ATX or SFX power supply.

  3. The 120W adapter supports CPUs with up to 65W TDP. This limits your processor choices to lower-power models.

  4. You are stuck with the included brick. No aftermarket power supply upgrades are possible with this connector.
