I think the main culprit is CPU/MB, so that’s the only thing needed a replacement. Many cheap alternatives (less than 200$) that can half the consumption and would pay itself in a year of usage easily. There is a Google doc floating around listing all the efficient CPUs and their TDPs. Just a suggestion, I’m pretty sure after a year it would payoff its price, there is absolutely no need for a 110w/h unless you’re running LLMs on that and even then it shouldn’t be that high.
