Before You Build
- Check the GPU power requirement: The PSU lists two PCIe 6+2-pin connectors. Confirm that your graphics card is compatible with the supplied connections and does not require a different native power connector.
- Remember that cables are fixed: This is a non-modular PSU, so its power cables remain attached to the unit. Plan cable routing and storage for unused connectors inside the case.
- Choose a compatible case: The PSU measures 150 × 150 × 86mm. Verify the case's PSU clearance and cable-routing space before installation.
- Allow adequate power headroom: A 550W PSU is not appropriate for every graphics card or high-power CPU combination. Check component recommendations and expected system consumption.
- Know the fan behaviour: ASUS's India technical specification page states that this model does not have a 0dB fan button or 0dB technology. Do not assume the fan remains off during light workloads.
- Check warranty terms: ASUS lists a six-year warranty for this product. Confirm regional warranty eligibility and seller terms for the exact unit.
