prob_01
Common root cause: Loose power connections or detached power cord.
Step-by-step solution: Unplug the PC from the wall outlet. Check if the power cord is securely connected to the power supply and the outlet. Reconnect all power cables from the supply to internal components (motherboard, etc.).
💡 Pro tip: Always listen for the 'click' when seating internal and external power cables.
📸 Evidence to provide support: Clear photo of all power cables connected to PSU and motherboard.

🚫 What NEVER to Do (Common Misuse Warnings)

⚠️ Connecting the power supply to incorrect voltage (e.g., 240V in a 120V outlet without a voltage selector switch, or vice-versa).
err_01
Consequence: Permanent damage to the internal components of the power supply and potentially other PC components.
✓ How to avoid: Confirm the power supply is auto dual voltage or set the selector switch (if present) to the correct voltage for your region before plugging it in. Note: Standard US wall outlets supply 120V. This 220V-240V appliance requires a dedicated 220V-240V outlet or a high-wattage step-up voltage converter to operate in the US.

⚙️ Hardware Setup, Adjustments & FAQs

❓ How do I know if the power supply is auto dual voltage or requires manual adjustment? cfg_01
Check the label on the side of the power supply. Auto dual voltage units do not have a voltage selector switch and operate on any voltage from 100V to 240V. If there is a switch labeled '120V'/'120V AC', set it to your region's voltage.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact support for warranty service if the power supply exhibits intermittent or permanent failures that are not resolved by basic cable and connection checks, if there is a burning smell, or if the computer fails to power on after all checks. Manufacturing defects are covered by the seller's warranty and marketplace return policy.
