Moderate energy use paired with minimal internal power requirements
Moderate energy use paired with minimal internal power requirements
I began tracking my PCs energy use because the room stays warm and I realized there’s little more to reduce. I observed that even when the CPU runs under 5 watts, the wall power spikes to around 150-200 watts. I understand the GPU consumes a lot at idle, but it doesn’t cover everything. Since I’m replacing the GPU today, I decided to check the overall power draw without its biggest consumer. I noticed in Windows, despite the Package Power in HWInfo being low (2-3 watts), the wall meter still shows 60-70 watts. Are there any further diagnostics I can run to identify the remaining ~50 watts? I’ll share the full details later.
Package designed for CPU, GPU drawing details included. You also have three SSDs, and turning off RGB won't significantly lower temperatures. A top-tier CPU, high-end GPU, and three SSDs generate heat. Does your room have a window? If it's closed due to summer, much of the heat comes from being in summer. The PC contributes a bit more to the warmth.
It's perfectly fine, nothing too unusual about a 50-70w idle draw. That level of power consumption is normal for components like the motherboard, RAM, hard drive, USB keyboard, etc. Just keep using your PC as intended—no need to stress. My setup runs smoothly in idle mode, with only about 10 watts extra compared to wall usage. The PSU handles it well, maintaining efficiency around 84%.
I was just wondering why they mentioned such a high idle power usage in that review. It seems their system with a top CPU and RTX 4090 was drawing 80 watts at idle, which is way more than mine with a 3090. Probably not a solid diagnosis, but I’ll leave it as is.
