Key figures
- Recommended PSU for iRacing: 600 W (80+ Bronze), minimum 550 W.
- Calculation: GeForce RTX 2080 Ti (250 W) + Ryzen 9 9900X (120 W) + 90 W; load ≈ 460 W, spikes ≈ 560 W.
- For the minimum requirements — 450 W.

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.
