Local AI Workstation Power and Electricity Cost Calculator
Board power is not the same as constant wall consumption. This calculator combines GPU utilization, the rest of the workstation, idle time and electricity price to estimate a realistic operating-cost range.
Estimate workstation power and electricity cost
Results combine GPU utilization, base-system draw and idle time.
Maximum board power is a sizing figure
A GPU may spend much of an inference session below its maximum, but the power supply must still handle peaks and transient loads.
The rest of the workstation is significant
CPU, motherboard, drives, memory, fans and conversion losses add to wall power. Dual-socket or multi-GPU systems can use much more than the GPU total alone.
Always-on idle time adds up
A workstation used as a server may be idle for most of the day. Efficient idle configuration and scheduled shutdowns can reduce annual cost.
Heat becomes a room-level issue
Nearly all consumed electricity becomes heat. High-power AI workstations need sufficient airflow and may increase air-conditioning demand.

Frequently asked questions
Does a 575W GPU always use 575W?
No. That is a maximum board-power reference. Actual use varies with model, runtime, power limit and utilization.
How much PSU headroom should I keep?
A common planning approach is to keep roughly 20 percent to 30 percent capacity above sustained demand while also following the GPU vendor recommendation.
Can undervolting reduce AI power use?
It may improve efficiency on some cards, but stability must be tested under the actual AI workload.
