A typical gaming PC uses roughly 80-120 W idle, 300-500 W while gaming and up to 600-900 W under synthetic load. Power draw varies with the GPU, so most of the gaming cost comes from the graphics card.
A 400 W gaming PC used 4 hours a day at $0.15/kWh costs about $7 per month — around $87 a year. Leaving it on 24/7 or mining raises that dramatically. This calculator makes the numbers concrete.
Check your electricity bill — it shows the price per kWh (kilowatt-hour), usually between $0.10 and $0.30. This calculator uses the average of $0.15 as a default.
At 4 hours of gaming per day, roughly $70-120 per year depending on your electricity price and GPU. This calculator gives the exact figure for your setup.
No — the PSU rating is a maximum, not a constant draw. A PC draws what its components need regardless of PSU size, so only actual wattage matters for the bill.
