Clean PC Builds
The fully modular design allows builders to route only the necessary power cables, helping improve cable management and the finished build's appearance.
Before You Build
- Check total system power: Confirm that 850W is appropriate for your CPU, GPU and other installed components, including transient power requirements.
- Verify the GPU power connector: The PSU includes a PCIe Gen 5.1 16-pin cable. Check your graphics card's connector type and manufacturer recommendations before installation.
- Use only compatible modular cables: PSU-side modular connectors are not universally interchangeable. Use the cables supplied for this exact PSU model or cables explicitly approved for it.
- Check case clearance: The PSU measures 150 × 150 × 86mm. Confirm that your case has sufficient room for the unit, connectors and cable bends.
- Understand the 0dB mode: The fan is designed not to spin until a certain load is reached. A stationary fan at low load is expected behaviour, not necessarily a fault.
- Confirm warranty and regional details: Warranty terms and included accessories can vary by market or batch. Check the local product listing and invoice for the exact terms.
