The cost to go from 460w to 750w is $50 . . . and the cost to go to 1000w is an additional $50. With regard to practicality, since the PSUs are proprietary, whichever you get with your original purchase you are essentially stuck with for life.
I have a 5-year-old laptop that I use as a workstation. When doing image post processing, and audio/video editing, the laptop runs super-hot and slow. I use Topaz AI software when doing image processing, which is compute intensive. A lot of the time however, I am just running productivity apps. I don't do gaming. I plan to get an XPS 8950, but I have some practicality and cost questions about my purchase. I like the 12700K, not just for the processing power, which I could use at times, but if I understand correctly, the K version comes with a good air-cooling unit which makes it cost-effective. The Nvidia 3060 seems like a good GPU for my purposes. Given that processor, cooling and GPU, I was wondering if the stock 460w PSU would work well? I ran the specs on the PS Calculator site, and it appears to cover the bases, especially since my actual CPU/GPU utilization is not sustained at a high level. I fully realize that the 750w would provide overhead, and it's often the default suggestion from enthusiasts. From a practical standpoint however, is there evidence that many of the Dell owners of the K variant, a GPU and a stock PSU are having PSU issues? Just trying to see this situation from more than just one perspective. TIA for your thoughts on this.
