Estimate the system
Use the selected CPU, GPU and other components to estimate a system’s power requirement. The result should be treated as planning input, not a measurement.
Check connectors and format
Verify the GPU power connectors, motherboard connectors, cable requirements and physical PSU fit for the case.
Leave sensible headroom
A qualified configuration process considers headroom and intended upgrades. Do not select a unit only by its headline wattage.
