The Challenge: Performance vs. Power Costs
High-performance computing often means high electricity bills, especially in regions with time-of-use pricing. Finding the balance between computational power and energy efficiency becomes critical when running resource-intensive workloads.
Understanding Power Usage
I have been setting up a workstation for off-loading compute-intensive LLM workflows from my desktop. The build includes dual Epyc CPUs with plans to add 4 GPUs for up to 128GB VRAM to run multiple agents in parallel. A key constraint was ensuring the system could run comfortably on a standard household 120V outlet.
Since I already use smart plugs throughout my home, I added one to monitor the workstation’s power consumption. However, checking power statistics using the kasa phone app or Home Assista
