Why can't we just get a range?
I care about TDP so I can estimate total power draw for my system when designing a custom build. I need to know about how big the PSU and UPS need to be, and getting a rough idea of electricity costs may influence my choices of components.
I can't trust the TDP figures and instead need to look up actual tests to know what it really draws, which is unnecessarily complicated.
- cuu508 7y agoPower consumption changes drastically depending on how many volts the motherboard feeds into the CPU. Different motherboards use different default values and different algorithms. And on top of that users can go in and tweak OC settings. The only honest TDP range they can give you would be: TDP between 10 and 300W. I have a 9700K (95W TDP). At idle, the entire system consumes 30W at the wall. When running Prime95, the entire system consumes 250W, and that's undervolted. The 95W number is utterly useless. If I had bought a 95W capable cooler, the system would throttle under load.
