I’ve got a 3800x that has plenty of performance but also uses a lot of power and I’m seriously considering upgrading to a 5700G. It’s about 170 from Amazon right now.
Comment on Super Power-Efficient ITX Nas CPU/Motherboard?
nopersonalspace@lemmy.world 9 months agoI have the nas connected to a UPS that reports it’s power draw and it sits at about 100W at all times. There are one or two other small devices connected to it usually, so the nas itself is probably using a hair less that that at idle, but still it’s quite high.

I guess that’s a good point, but then is the right move to just get the lowest power CPU possible? I really don’t need it to do all that much and rn it’s hogging power.
stown@sedd.it 9 months ago
Maybe not the lowest power possible… I wouldn’t recommend running your NAS on a raspberry pi even though plenty of people do

Even the low powered CPU /boards will only idle low power. Embedded and ITX can idle at 6W but the HDDs will still need power, and spinning down/up HDDs reduces their total lifetime. The only real solution there is to reduce the amount you use by swapping to larger fewer models.

You’re right and that’s exactly my plan! I’m going to get 2 20TB drives the next time I need to upgrade, that way I can keep the number of drives low.
With my current power usage and energy prices I’m paying $280 per year for this server alone, so I’m pretty well incentivized to replace parts (particularly since I can sell the parts I’m replacing to offset even further). With my current plans I’ll see a positive ROI within a year almost guaranteed

This seems very suspicious, get a cheap watt metter and test it with that. If it still says 100W I would say there’s something wrong in your CPU, motherboard or software. Not necessarily the CPU, can be the motherboard or simply your Linux is set to run the CPU at full clock all the time.
Btw, I have a Ryzen 5 2600 and that thing goes down to 20W or so.

I specifically had to set things up in the BIOS so that it would never enter any efficient power/sleep states. It’s a bug in the OS I’m using that was forcing me to do it, otherwise the whole thing would lock up on me.
That said, I have some smart-plugs that do power monitoring. I can try hooking up the nas to one of those just for kicks, it should be accurate enough for this sort of thing.

There is an issue with ryzen and certain PSUs that when it goes to idle it pulls so little power that the psu thinks it’s off and kills the power, it can appear as a hang. there should be an option in the bios to change it to “typical power” or named something similar.
nopersonalspace@lemmy.world 9 months ago
Oh interesting, that sound plausible. I’ll check out the bios and see if I can find that setting. Thanks!
TCB13@lemmy.world 9 months ago
This is most likely why you’re running at 100W all the time. No need to further measure anything. Reset your BIOS to defaults, update the OS and you should be good.
nopersonalspace@lemmy.world 9 months ago
It’s not that easy sadly. The entire NAS runs on Unraid and the issue is with that OS. I can’t switch without totally restarting from scratch which would be a huge data migration, and a massive PITA configuration-wise.
