Budget PC (GTX 1660 Super) electricity cost — 2 hours gaming + 6 h idle standby
PC is on for 8 hours (2 h active gaming + 6 h idle/video/browsing) on 5 days. Idle system draw estimated at 80 W. A <strong>Budget PC (GTX 1660 Super)</strong> draws 245 W total (GPU 125 W + rest of system 120 W). Cost: £1.27/week at Ofgem cap 26.11p/kWh (1 July to 30 September 2026).
Budget PC (GTX 1660 Super) — 2 hours gaming + 6 h idle standby: 0.245 kW × 2 h active = 0.490 kWh + 0.08 kW × 6 h idle = 0.480 kWh. Session total: 0.970 kWh = 25.3p. Weekly (5 sessions): £1.27. Monthly: £5.49. Annual: £65.85. Source: Nvidia / AMD / Intel — published TDP specifications for GPU and CPU components + Ofgem (OGL v3.0).

How the cost is worked out
- Active gaming (2 h): 245 W ÷ 1000 × 2 h = 0.490 kWh × 26.11p = 12.8p.
- Idle (6 h): 80 W ÷ 1000 × 6 h = 0.480 kWh × 26.11p = 12.5p.
- Per session total: 0.970 kWh = 25.3p.
- Weekly: 25.3p × 5 days = £1.27.
- Annual: £1.27 × 52 = £65.85.
