I am trying to track down exactly where the power is going on my laptop, which is currently drawing a steady baseline of around 60 Watts when the dedicated GPU is disabled.
I am running an MSI GS76 Stealth 11UH-078 (17.3", 4K 120 Hz variant) (mirror, specs) laptop with the following specifications:
- CPU: Intel Core i9-11900H
- CPU: Nvidia NVIDIA RTX 3080
- RAM: 64 GB DDR4
- Storage: 2x 8TB WD_BLACK SN850X NVMe SSDs
- OS: Windows 11 25H2 Pro x64
Using HWiNFO64, I can easily see the real-time telemetry for the CPU power, in my case (screenshot):
CPU Package Power: ~11.433 WIA Cores Power: ~5.146 W
However, this leaves roughly 45 Watts unaccounted for.
My ballpark estimate is:
CPU Package: ~20 W
Dual 8TB High-Performance SSDs (Active Scan): ~15.0W
Display Panel (17.3" at 360Hz): ~8.0W
Cooling Fans (High Speed): ~6.0W
64GB RAM & Motherboard Efficiency Losses: ~5.0W
Wi-Fi / Background Bluetooth: ~2.0W
-> Total Current Draw: ~60 Watts.
But that's mostly a guess. How can I view/estimate the real-time wattage consumption for individual laptop components (SSD, Fans, RAM, display, etc.)?
