Lian Li RS 1000W 80+ Gold Fully Modular PSU - White

Fully modular means all cables are detachable. You only connect the cables you need, which drastically reduces cable clutter, improves airflow, and makes building or upgrading your PC much easier.

1000W is suitable for high-end systems with powerful CPUs and multiple GPUs or high-end single GPUs like the NVIDIA RTX 4090 or AMD Radeon RX 7900 XTX. It provides significant headroom for overclocking. For lower-spec systems, a lower wattage PSU might suffice.

This certification indicates a high level of power efficiency. An 80+ Gold PSU is rated to be at least 87-90% efficient at various load levels (20%, 50%, 100%), meaning less energy is wasted as heat, saving electricity and reducing thermal output.

It is strongly advised NOT to mix modular cables from different PSU brands or even different models within the same brand, as pinouts can vary and may lead to component damage or fire.

The rotatable AC inlet allows you to adjust the orientation of the power cord connection. This is particularly useful in tight spaces or cases where the standard inlet position might interfere with other components or case panels.

Please refer to the official Lian Li product page or documentation for the most current warranty information specific to this model.

Check the product specifications or manual for details on fan operation modes. Many modern PSUs feature a semi-fanless mode where the fan remains off at low loads for silent operation.

Verify the AC power cord is securely connected to both the PSU and the wall outlet. Ensure the power switch on the back of the PSU is in the 'ON' position. Check that all modular cables are firmly seated in both the PSU and the motherboard/components.

Ensure all power cables are correctly and fully connected. Verify that the PSU's wattage is sufficient for all installed components. Check for any signs of overheating on the PSU or other components.

Some PSUs feature a fanless mode at low loads. Check if the fan spins up under heavier load. If not, and you suspect an issue, consult the product manual or contact support.

Listen carefully to identify the source of the noise. If it's fan noise, ensure vents are clear. If it's an electrical buzzing or grinding, discontinue use and contact support.
