Have you measured the power consumption of your "high power consumption" server?

Have you measured the power consumption of your "high power consumption" server?
- jeffbee 1y agoSeriously. You can get running states around 1W these days.
- blurbleblurble 1y agoWhat to do about this? https://forums.developer.nvidia.com/t/phantom-rtx-5090-high-idle-power-consumption-any-fixes/327225 https://forums.developer.nvidia.com/t/phantom-rtx-5090-high-...
- jeffbee 1y agoI suggest not putting a ridiculous GPU in your backup server.
- overfeed 1y agoNot everyone's "home server" is a backup server - some are for AI experiments.
- silon42 1y agoThat one should be Wake-On-LAN
- overfeed 1y agoI wouldn't want to fiddle with WoL just to get my self-hosted LLM-assisted code-completion working when I pickup my old and underpowered laptop on the couch for some quick hacking. Wake-on-any-network-activity would be perfect, and has superior UX.
- moandcompany 1y agoYou can use nvidia-smi to set a target maximum power draw and performance mode to bring idle power levels down. Also make sure your computer is using the server/headless mode driver to keep idle power consumption down.
- supertrope 1y agoIf one can afford a GPU with a MSRP of $1999 and was scalped for $2999 during the initial craze, you are probably not struggling to pay your electric bill.
- wiredpancake 1y agoRunning states around 1W? How?
- deleted 1y ago[deleted]
- jeffbee 1y agoOnly 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.
- wiredpancake 1y agoI do basically all of that, CPU idles around 5% but still consumes over 100W. (Minus the Wireless part) (5800X + 64GB) 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.
- jeffbee 1y agoWhatever software you are using is totally, utterly broken. Not sure what else I can tell you. Even a completely decked out Ryzen AI Max Pro 395 idles at 5W in Windows S0 (see: https://h20195.www2.hp.com/v2/getpdf.aspx/c09133726.pdf https://h20195.www2.hp.com/v2/getpdf.aspx/c09133726.pdf)
- supertrope 1y agoChiplet based Ryzen CPUs inherently have higher idle power draw. Monolithic chips like 5600G have lower idle power draw. The motherboard, power supply, and internal peripherals all need to be carefully selected to get a really low idle figure.
- supertrope 1y ago1W is a unicorn as just plugging in a power supply with no PC parts hooked up will register 1W. <10W is more realistic. Select a PC that can run off a laptop charger. Check manufacturer spec sheets for the idle power consumption. Don't install any PCIe cards or hard drives. Use powertop --autotune.
- shellwizard 1y agoAre you talking about processor's C-states? My old 6th gen i3 stays most of the time idling around C8, averaging 5w, really impressive, I suppose newer gens will be even more efficient
- jeffbee 1y agoC8 is a good state if you can get it. Intel is really good at this. They don't even bother energizing the L3 caches immediately when exiting deep package C-states. But there are lots of conditions that will inhibit C8, notably an Ethernet link on a NIC capable of PTP. This is why wireless is better.
- xioxox 1y agoAlthough Intel processors are efficient, modern AMD processors have much higher idle power usage, due to their chiplet design. They typically use at least 20W more power.
- BizarroLand 1y agoMy home server setup when running at full tilt consumes approx 160 watts iirc. I'd love it if I could turn off my systems for when I really need them.
- 2OEH8eoCRo0 1y agoDo you usually run it full tilt? What's it typically using on average? I've forgotten how much mine averages, I only remember being surprised how little it sips because it's mostly idle. It's surprising because reddit (and HN) would make you think you're throwing away tons of money unless you go with some tiny ARM board and that's not true.
- ThatPlayer 1y agoMine idles at around 130W from the walls. I think it's mostly the hard drives, maybe the SAS controller. I've migrated a few services to a miniPC and started turning it off too. The main issue for me is the heat. I've got it next to me and 130W of heat adds up in the summer.
