Frequently Asked Questions — PC & Server Power Cost
How Much Electricity Does a 450W Gaming PC or Home Server Cost Per Month?
Running a 450W workstation or gaming rig 8 hours/day at $0.16/kWh consumes 108 kWh per month, adding $17.28/month ($207.36/year) to your electric bill. You can also open our dedicated guide (450W PC Monthly Electric Cost) or click the preset buttons above to test this exact configuration interactively.
How do I optimize Average System Power Draw (Watts) and Hours Running per Day for better PC & Server Power Cost performance?
At the default benchmark (Average System Power Draw (Watts): 320, Hours Running per Day: 12), balancing both inputs prevents bottlenecks and wasted budget. Test the built-in presets above to compare standard industry tiers.
