What to look for in a PSU

Look for

  • A DC-DC, LLC resonant platform from a known manufacturer (OEM)
  • A full protection set: OCP, OVP, UVP, SCP, OPP, OTP
  • 105 °C Japanese capacitors
  • ATX 3.1 with a native 12V-2x6 cable (for RTX 40/50)
  • 80 PLUS Gold / Cybenetics Gold or better
  • A 7–10 year warranty and independent test reviews

Avoid

  • No-name units given away with cases
  • Units with no certification, or sold on "peak / max" wattage
  • Cheap group-regulated series at high wattage
  • Brands that don't list their protection circuits
  • Warranties shorter than 2 years
  • Models with no reviews, sold on wattage alone

How we estimate

Every graphics card has a performance index for 1080p, 1440p and 4K, and every CPU has a gaming index. A game's FPS on the reference system (RTX 4070 + Ryzen 7 9800X3D, High preset) is scaled by the card's index. The highest FPS the CPU can deliver in that game is calculated separately. The result is a soft minimum of those two ceilings, with penalties when VRAM, RAM or thread count fall short. The range shown is ±10%.

GPU_fps = Ref_fps × (Card ÷ RTX 4070)^e × Preset × VRAM CPU_fps = Ref_cap × (CPU ÷ 9800X3D) × Threads FPS ≈ (GPU_fps⁻⁶ + CPU_fps⁻⁶)^(−1/6) × RAM PSU_peak = Card TBP + CPU max power + 50 W Recommended ≈ PSU_peak × 1.4 (minimum: × 1.05)
  • Graphics card indexes: Tom's Hardware GPU hierarchy (June 2026; Ryzen 7 9800X3D, 11 games, Ultra). Older cards are converted from the same site's 2022–2024 table.
  • CPU indexes: Tom's Hardware 1080p gaming scores (October 2026). Ryzen 5000 and older, and Intel 11th gen and older, are approximate.
  • Per-game reference FPS, VRAM and RAM needs are approximate for now and will be updated with test results.
  • Graphics card detection reads only the card name your browser reports; nothing is sent anywhere.
  • Integrated graphics ("No graphics card"): speed relative to a desktop GTX 1650 from Tom's Hardware, TechSpot and Phoronix tests, assuming dual-channel memory. Single-channel memory costs about 45%.
  • RAM: speed × channels sets memory bandwidth. Below the memory each CPU was tested with, CPU-bound FPS drops (less on X3D chips); integrated graphics are far more sensitive. XMP/EXPO tips use each platform's usual speed.
  • Upscaling: FPS is computed at the internal resolution (Quality 67%, Balanced 58%, Performance 50%, Ultra performance 33% per axis), plus the upscaler's own cost per frame.
  • Not yet included: laptop GPUs, ray tracing, frame generation and 1% lows.
