Have you measured the power consumption of your "high power consumption" server?
The main issue for me is the heat. I've got it next to me and 130W of heat adds up in the summer.

Making a Linux home server sleep on idle and wake on demand – the simple way - https://news.ycombinator.com/item?id=35627107 - April 2023 (237 comments)

Seriously. You can get running states around 1W these days.
Running states around 1W? How?
Well done. But note: you can grab an ATX control board, or configure the RPi as a USB Gadget to wake the machine via power button or keyboard.
In in the end I just went the whole hog and set up a PiKVM, so now if I mess up the machine's networking (or even completely break the OS) I can still recover it remotely even though it doesn't have a proper BMC or anything like that.
In general this approach seems ugly in principle but I really like it in practice. It lets you retrofit solid remote capabilities onto consumer hardware. That way you have such a broader market to buy from.
All this complexity to save a few bucks per year on your electricity bill? This is ridiculous, the Pi costs far more than what you can be expected to save.
In many European countries electricity is quite expensive. In the U.K. for example, running 20 watts nonstop for a year will cost you around $65 on a typical tariff. If you have more than one home server the savings can quickly add up.
Anyway it's not about the money for me it's any the aesthetics. Burning power for nothing is yucky.
Edit: just been Googling around. OP is running one of these HP mini PCs. They are pretty efficient! Some go well below 10W. So yeah I would say for the specific use case it's unlikely to matter very much. But still it's a useful thing to be able to do in general.

What to do about this? https://forums.developer.nvidia.com/t/phantom-rtx-5090-high-...

Only put the RAM you need in the box, use peripherals with working ASPM, attach them to the northbridge PCI ports instead of the CPU's root ports, use wireless instead of wired networking, and don't attach a display.

I can enable Eco Mode in the BIOS, which will bring down the CPU to about 65W max although its still at about 100W total system.
