DMA cards are tiny FPGAs. They draw minimal power and produce minimal heat. But people ask, so here are the measured numbers.
Power numbers
Captain DMA 75T: 6.8 W idle, 9.2 W under read load. Stark100T: 4.4 W idle, 7.1 W load. Squirrel 35T: 3.2 W idle, 5.0 W load. LeetDMA: 10.5 W idle, 14 W load. All measured at the PCIe rail with a riser sensor.
- Captain DMA 75T — 9.2 W max
- Stark100T — 7.1 W max
- Squirrel 35T — 5.0 W max
- LeetDMA — 14 W max
Thermals
All cards stay under 60 °C with case airflow. Captain DMA 75T peaks at 56 °C under 8-hour CS2 sessions in a Fractal North case with 2 front fans.
"Power draw is negligible. Focus on the demo."
