⚙️ Hardware Setup, Adjustments & FAQs

❓ How do I know if the power supply is dual-voltage (12V/24V DC auto-switching) or has a manual selector switch? cfg_01
Check the label on the side of the power supply. If there is a switch marked '110V/220V' or '100-240V' with a physical switch, it's a manual selector. If it only indicates '100-240V' without a switch, it's automatic.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact support under the seller's warranty if the power supply does not turn on after checking all connections and the voltage selector switch, exhibits persistent abnormal noises after cleaning, or if the PC experiences constant instability/shutdowns even with the power supply correctly installed and not overloaded, indicating a potential manufacturing defect.
