How we calculate
The graphics card and processor come from the game’s official requirements (Steam or the publisher) and are matched to the FPSHQ catalog only by exact model name; power is the rated TDP from the catalog.
One formula for the whole site: load = GPU TDP + CPU TDP + 90 W (board, memory, drives, fans); peak = 1.4 × GPU TDP + CPU TDP + 90 W; recommended PSU — the nearest standard rating not below max(load × 1.3; peak).
If the CPU in the requirements is not recognized, a mid-range 105 W class is used — this is marked on the page.
