PSU wattage: start with a complete build
A single processor or GPU power value is not a complete system power budget. Missing components can make a confident-looking total misleading.

Collect the inputs before calculating
List the processor, graphics card, board, memory, drives, cooling and other powered devices. Source power figures can describe different scopes: processor limits, board power or a recommendation for a whole system. Keep those meanings separate. A sum of a few available numbers is not evidence that an incomplete configuration has a verified requirement.
Connections and fit still matter
A PSU's rated wattage does not tell you which connectors it supplies or which modular cables are safe to use. Check its exact model, form factor, dimensions and the GPU connection requirements. Verify the cable compatibility documentation rather than reusing cables because their plugs appear similar. Also check that the case accommodates the PSU and space needed for its connections.
Read a recommendation with its assumptions
A calculator is a planning aid whose result depends on its inputs and method. RigPrism refuses a full recommendation when component power evidence is incomplete. That protects you from treating missing values as zero. Complete the manual checklist from source documentation, preserve the assumptions with the saved build, and seek a suitable tested unit rather than treating a numerical margin as a reliability certification.
Your check before choosing parts
- Include every powered component.
- Keep power figures' scopes explicit.
- Verify connectors, cables and case fit.
