Free calculator, browser-only. Sources verified on 2026-09-19. Last updated: 2026-09-19. Written by Y.W. Fung
A mid-range gaming PC draws 300-450W under load, about $0.06 an hour and $5-$9 a month at 4 hours a day. A high-end rig can hit 700W. Capping frame rates, enabling sleep and using a smart strip typically saves $25-$60 a year.
At a glance
- What it is: a 300-700W system plus monitors and peripherals.
- How much it saves: $25-$60 a year from frame caps, sleep settings and a smart strip.
- Payback time: 6-12 months on a $25 smart power strip.
Gaming hardware has grown far more power-hungry over the last decade, and a high-end graphics card alone can now draw as much electricity as a small space heater at full load. Whether a gaming habit meaningfully affects an electricity bill depends heavily on the hardware, the settings used, and how many hours a day the machine is actually under load versus idling on a desktop. This guide compares gaming PCs of different tiers against consoles, and shows the real cost per hour and per month of a regular gaming session.

TV Power Consumption: LED vs OLED vs Large Screen Cost Per Hour
A 50-inch LED TV typically draws 60-100W, costing about $0.01-$0.02 per hour or roughly $3-$5 a month watching 5 hours a day at the US average rate of $0.16/kWh. A similarly sized OLED draws somewhat more, 80-120W, costing about $4-$6 a month, while a large 65-75 inch set of either technology can draw 100-200W, roughly doubling the monthly cost.

How Much Electricity Does an Air Conditioner Use? (Cost Per Hour, Day and Month)
A small window AC (5,000-8,000 BTU) draws 450-800W and costs roughly $0.07-$0.13 per hour at the US average rate of $0.16/kWh, or about $17-$31 a month running 8 hours a day. A mid-size 12,000 BTU unit draws about 1,200W, costing around $0.19 per hour and $46 a month; in the UK the same unit costs roughly 31p per hour and £75 a month at 26p/kWh.

How Much Does a Refrigerator Cost to Run Per Month and Per Year?
A modern standard-size refrigerator (18-22 cu ft) uses roughly 350-500 kWh per year, costing about $6-$9 a month or $70-$100 a year at the US average rate of $0.16/kWh. In the UK the same fridge costs roughly £5-£8 a month at 26p/kWh; an older pre-2000 fridge can use two to three times as much energy for the same size.

How many watts does a gaming PC use?
The graphics card is almost always the single biggest power draw in a gaming PC, often consuming more electricity on its own than the rest of the system combined. A budget or mid-range build with a card like a mainstream GPU and a mid-tier CPU typically draws 250-350W total under gaming load. A well-specced enthusiast build with a high-end GPU and CPU can reach 450-550W, and the newest flagship graphics cards, which can individually draw 350-450W at full power, push a complete high-end system to 600-750W under heavy load. By contrast, the same PC sitting idle on the desktop or browsing typically draws only 60-100W, which is why total gaming cost depends so much on actual hours spent in demanding games versus general computer use.
How much does gaming cost per hour and per month?
Applying the standard formula , watts divided by 1,000, multiplied by hours, multiplied by rate , makes the comparison straightforward. A 350W mid-range PC gaming for 3 hours a day uses about 1.05 kWh, costing roughly $0.17 a day and around $5 a month at $0.16/kWh. A 600W high-end PC doing the same 3 hours a day uses 1.8 kWh, costing about $0.29 a day and $8.60 a month. Serious gamers who play 5-6 hours a day, common among enthusiasts and streamers, will see a high-end system add $14-$17 a month, and running a second monitor and a webcam or streaming encoder simultaneously can add another 50-100W on top of the base system draw. Use the calculator on the home page with your PC's rated wattage and your own hours to check your exact monthly cost.
- Budget/mid-range PC (~300W): about $0.05/hour, $14/month at 3 h/day
- High-end PC (~500W): about $0.08/hour, $22/month at 3 h/day
- Enthusiast PC, top-tier GPU (~700W): about $0.11/hour, $31/month at 3 h/day
- PlayStation 5 or Xbox Series X (~180W): about $0.03/hour, $8/month at 3 h/day
- Nintendo Switch (~10-18W): under $0.01/hour, roughly $1/month at 3 h/day
Are consoles cheaper to run than a gaming PC?
Modern consoles are engineered around a fixed, efficient hardware target and typically draw 120-200W during active gameplay, considerably less than even a modest gaming PC, because they lack the overhead of a full operating system, multiple storage drives, RGB lighting and a discrete cooling system sized for a much hotter, more flexible chipset. A PlayStation 5 or Xbox Series X gaming for 3 hours a day costs roughly $8 a month at US average rates, about a third of even a modest gaming PC and a tenth of a high-end enthusiast build. Handheld consoles like the Nintendo Switch or Steam Deck draw only 10-20W, making their electricity cost close to negligible regardless of how many hours are played.
How much do monitors and always-on habits add?
A gaming monitor adds a meaningful amount on top of the tower itself. A standard 27-inch 1440p monitor draws 30-50W, while a large curved ultrawide or a high-refresh 4K panel can draw 60-100W. RGB lighting, multiple case fans and a liquid cooling pump typically add only a few extra watts each, so they rarely move the total noticeably despite their reputation. The bigger hidden cost is leaving a PC on 24/7 for downloads, background rendering or always-on Discord presence: even idling at 70-100W around the clock adds roughly 50-72 kWh a month, an extra $8-$12 on the bill before any actual gaming happens. Enabling sleep mode when the PC is not in active use is the single easiest way to eliminate this waste.
How can you lower gaming electricity costs?
- Cap the frame rate to your monitor's refresh rate; higher uncapped frame rates draw more power for no visible benefit
- Enable your GPU's power limit or efficiency mode in demanding but not competitive games
- Turn on sleep mode after 15-20 minutes of inactivity instead of leaving the PC running idle all day
- Undervolt the CPU and GPU if comfortable doing so; many builds lose 10-15% power draw with negligible performance loss
- Use an efficient 80 Plus Gold or Platinum-rated power supply; a poor-efficiency unit wastes 10-15% of the power it draws as heat

Frequently asked questions
How much does it cost to run a gaming PC for an hour?
- A mid-range gaming PC drawing about 300-400W costs roughly $0.05-$0.06 per hour at $0.16/kWh; a high-end PC drawing 600-700W costs about $0.10-$0.11 per hour.
Does gaming use a lot of electricity?
- It uses noticeably more than general computer use because the graphics card draws several times its idle wattage under load, but a typical few hours a day of gaming still adds only $10-$30 a month for most PCs.
Is a PS5 cheaper to run than a gaming PC?
- Yes, considerably. A PS5 draws roughly 180W during gameplay, about a third of a mid-range PC and a tenth of a high-end one, costing around $8 a month for 3 hours of daily play versus $14-$31 for a PC.
Should I turn off my gaming PC every night?
- Yes, for cost purposes. An idling PC left on overnight can draw 60-100W continuously, adding roughly $8-$12 a month in wasted electricity compared with sleep mode or a full shutdown.
How much does a graphics card add to the electricity bill?
- A high-end graphics card alone can draw 300-450W under load, often more than the rest of the PC combined, adding roughly $0.05-$0.07 per hour of gaming compared with an entry-level card.
Key takeaways
- Mid-range gaming PCs draw about 300-450W; high-end builds draw 550-750W under load
- Typical daily gaming costs $12-$25 a month for a PC, versus around $8 for a console
- The graphics card is usually the single biggest power draw in the whole system
- Idle desktop use still draws 60-100W; sleep mode avoids paying for unused hours
- Capping frame rate and undervolting can cut gaming power draw by 10-20% with little performance loss
Methodology & data sources
Every cost figure here is calculated with kWh = (watts × hours per day) ÷ 1000, multiplied by a regional average electricity price: about $0.16/kWh (US), 26p/kWh (UK), NT$3.5/kWh (Taiwan), HK$1.5/kWh (Hong Kong) and ¥31/kWh (Japan). Appliance wattages are taken from manufacturer nameplate ratings and published energy-label ranges for current models. Real bills vary with climate, insulation, appliance age and tiered or time-of-use tariffs, so we recommend re-running the numbers with the unit rate printed on your own latest bill.
