Total $cost of inference since I got my DGX Spark

[whpthomas]

AUD$ 46.5 for 88 days (141 kWh)

This is the power consumed by everything running on my desktop, DGS Spark, Mac Mini, 3x Monitors, network switch.

Anyone else been tracking this?

Plugged in 18th Feb 2026

I keep mine plugged into its own Wi-Fi smart power switch with metering. Has totaled 98 kW on its own since mid-Feb.

I don’t track the power directly, but I do track the inverse: tokens (input and output) sent through models with comparison to cloud inference costs.

Mapped to Azure Foundry rates, when not left idle, the device pays for itself in a surprisingly short time.

Don’t have price on hand but usage looks like this

You seem pretty happy, based on your Spark reflection!

What device is this power monitor LCD from?

AUD $46.5 for power, Base consultant rate at AUD $150 per hour spend to setup and optimize your DGX Spark, current DGX Retail price AUD$7990 x 2 (assumed 2 units, not sure), not sure which switch you are using , ball park AUD$1500. Add them up :-D

I use Tuya API to gather metrics and put it in VictoriaMetrics
