TDP, TBP and power limits explained
Power-related specifications describe different concepts depending on manufacturer and component, so they should not be treated as identical PSU-sizing numbers.
Key things to check
- Read vendor definitions
- Measure whole-system needs separately
- Cooling requirements relate to sustained heat
Why it matters for gaming
PC performance is the result of several components working together. Frame rate, frame-time consistency, loading, temperatures and upgrade compatibility can all be affected by the surrounding system. Use this guide as a starting point, then verify the specifications for your exact hardware.
Before you buy or change anything
Check the exact model numbers in your PC, read the motherboard and component documentation, and pay attention to FrameForecast compatibility warnings. A faster component is only a useful upgrade when the platform can safely support it and it improves the workload you actually care about.
