What Does It Cost to Run a Desktop Computer in Texas?

Running a desktop computer in Texas costs about $7.40 a month — $90.01 a year — at the state's average rate of 16.44 ¢/kWh. That's roughly $10.95 a year less than a household paying the national average pays for the exact same desktop computer. The estimate assumes a typical 250-watt desktop computer running 6 hours/day, at the all-in average rate (delivery, fixed charges, and utility fees already included; locally billed taxes vary by area).

How much electricity does a desktop computer use?

A desktop computer draws roughly 150-400 W; we use 250 watts running 6 hours/day. That comes to 1.50 kWh a day — 45.0 kWh a month, or 547.5 kWh over a year — using kWh = watts × hours ÷ 1000.

A desktop uses more than a laptop but less than a gaming rig — and what it costs you depends on whether it's idling on email or pushing through heavy work, plus the monitors and gear plugged in around it. Texas prices that energy at 16.44 ¢/kWh, against a 18.44 ¢/kWh national average.

These figures use the all-in average rate. Your actual bill can run higher when separately billed taxes, seasonal pricing, and fixed monthly fees apply.

What changes the cost the most?

Two things move this number: your state's rate, which you can't change, and how hard the appliance works, which you often can. For a desktop computer, that mostly comes down to CPU/GPU workload, monitor count, sleep vs active time.

Source & Method

Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: May 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility. For what's inside the all-in rate, see hidden electricity fees; for how rates and estimates are defined, see the methodology hub.
