Power Station for a Gaming PC
Gaming desktops are one of the heavier common loads people run off a power station — this calculator is preconfigured with a typical mid-to-high-end gaming PC under load, so you can plan LAN parties, power outages, or off-grid gaming sessions realistically.

Enter your power station’s capacity in Wh to see a runtime estimate.
This is an estimate. Real-world runtime can be lower than the theoretical figure due to inverter efficiency losses, fluctuating (not constant) device draw, ambient temperature, battery age/health, and other factors. Always check your power station’s official specifications before relying on it for critical use.
PSU rating vs. actual power draw
Your PC's power supply unit (PSU) is rated for its maximum possible output — a "750W PSU" doesn't mean the PC draws 750 W continuously. Actual draw depends on your CPU and GPU under real load, and typically sits well below the PSU's rating even during gaming. This calculator defaults to 350 W as a reasonable estimate for a mid-to-high-end build actively gaming — use a wattage meter or your system monitoring software for a precise figure on your own PC.
Don't forget the monitor
A gaming monitor typically adds another 25–80 W depending on size, resolution and refresh rate — high-refresh-rate and larger panels draw more. Add your monitor as a custom device in the calculator above for an accurate combined total.
Laptop as a lower-power alternative
A gaming laptop draws dramatically less than a desktop tower — often 65–180 W under load versus 300 W+ for a desktop — which translates directly into several times the runtime from the same power station. If extending your session matters more than peak performance, a laptop stretches battery capacity much further; try the laptop quick-calc button above to compare.
Frequently asked questions
How long will a power station run a gaming PC?
At a typical 350 W load and 85% efficiency, a 1000 Wh power station provides roughly 2h 26m of gaming time. A 2000 Wh unit roughly doubles that to around 4h 51m. Use the calculator above with your PC's actual measured draw for a precise figure.
Will an idle or menu-screen PC last longer than the calculator suggests?
Yes — this calculator assumes continuous load at the wattage you enter. A PC idling at a menu or doing light work draws considerably less than one under full gaming load, so your practical runtime during a mixed session will generally land between the idle and full-load figures.
Can a power station handle a gaming PC's startup power spike?
Desktop PC power supplies generally have a smoother startup curve than motor-driven appliances (like a fridge or AC), so surge is usually less of a concern — but very high-end systems with large GPUs can still draw a brief spike. Check your power station's rated continuous and surge wattage against your PSU's rating if you're running a high-end build.
