Nvidia GTX 1660 Super TDP 125 W (published spec); rest of system ~120 W typical budget build

How the cost is worked out

  1. System power: 125 W (GPU) + 120 W (CPU + rest) = 245 W total.
  2. Per session: 245 W ÷ 1000 × 1 h = 0.245 kWh × 26.11p = 6.4p.
  3. Weekly: 6.4p × 3 sessions = 19.2p.
  4. Monthly: 19.2p × 52 ÷ 12 = 83.2p.
  5. Annual: 19.2p × 52 = £9.98.
