Gaming PC power consumption is usually 250–450 watts while gaming for a mid-range build, against roughly 150–250 W for a gaming laptop and about 200–235 W for a PS5. At typical Kenyan home rates, that’s around KES 5 to 15 per hour of gaming, screen included, so electricity is rarely the deciding cost.

Watts used by PC, laptop and console
Typical draw from the wall while playing a demanding game:
| Device | While gaming |
|---|---|
| Entry gaming PC (e.g. RTX 4060 class) | 220–320 W |
| High-end gaming PC | 400–600 W |
| Gaming laptop (plugged in) | 150–250 W |
| PS5 or PS5 Pro | 200–235 W |
| Monitor or TV | 30–150 W |
The power supply rating isn’t the draw: a 650 W PSU or 230 W charger is a maximum, not constant use. In gaming PC vs gaming laptop power consumption, the laptop typically uses 30–50% less for similar settings, because laptop parts are tuned for efficiency.
Cost per hour in KPLC tokens
One KPLC unit is 1 kWh. Find your real price per unit from your last token SMS (amount paid ÷ units). For most homes it’s roughly KES 25–30 per unit once levies and VAT are added; our KPLC tokens calculator guide explains how to work out yours.
Cost per hour = watts ÷ 1,000 × price per unit
At KES 28 per unit:
| Setup (incl. screen) | Watts | Per hour | 4 hours a day for 30 days |
|---|---|---|---|
| Gaming laptop | 200 W | KES 5.60 | KES 670 |
| PS5 + 43″ TV | 300 W | KES 8.40 | KES 1,010 |
| Mid-range PC + monitor | 380 W | KES 10.60 | KES 1,280 |
| High-end PC + monitor | 550 W | KES 15.40 | KES 1,850 |
Heavy use can push a home into a higher tariff band, raising the price of every unit.
UPS and inverter sizing
A UPS buys minutes, not hours. It keeps the PC running through a blackout long enough to save and shut down.
- UPS ratings are in VA; real watts are roughly 0.6–0.7 × VA on most budget models (check the label).
- Size the UPS at about 1.5× your load. A 380 W PC + monitor needs roughly a 1,000–1,200 VA unit; a 650 VA UPS is often too small for a gaming PC.
- Laptops already have a battery, so they only need a UPS for the router.
To keep gaming through outages, you need an inverter with batteries. Rough maths: battery Wh × usable share ÷ load. A 12 V 100 Ah battery (1,200 Wh) gives about 600 Wh usable from lead-acid, or about two hours at 300 W. See UPS vs inverter for which suits you.
Ways to cut power use
- Cap the frame rate to your screen’s refresh rate (60 or 144 fps). The GPU stops working flat out.
- Turn the PC fully off, not sleep, overnight.
- Switch off Rest Mode extras on a PS5 (powering USB ports, staying online) if you don’t need overnight charging or downloads.
Choosing between the two? Gaming laptop vs gaming PC covers price and performance.
Quick answers
More than a laptop or console, typically 250–450 W while gaming, but it’s still only about KES 7–13 an hour at typical Kenyan rates.
Multiply your setup’s watts by hours played, divide by 1,000, then multiply by your price per unit. Four hours a day on a PS5 and TV is about KES 1,000 a month.
About 1.5 times your load in watts, converted to VA. Most gaming PCs need 1,000 VA or more.
