teedub Posted September 30, 2020 Share Posted September 30, 2020 The power supply on my ancient server just bit the bullet, so I'm using it as an exuse to start from afresh. The server is mainly used for Plex, NAS and home automation, so well need to be available 24/7. However I don't want to break the bank in running costs, so am looking for a build that will maybe idle around 40W. I'm finding it hard to find decent idle power consumption for various systems, so my question is: What CPU and components are you rocking, and what is your idle/average power consumption?

Tom3 Posted September 30, 2020 Share Posted September 30, 2020 Using a Xeon D-1541 (8 core / 16 thread) 2.1 GHz, motherboard is Supermicro X10SDV-TLN4F. Idle power runs between 21 and 25 watts. 32G ECC RAM, NVMe Cache. 1 Quote Link to comment
Dase Posted September 30, 2020 Share Posted September 30, 2020 I idle at 65 watts, but that's with two drives always spun up, a parity drive and a torrent/download drive, and 13 more on standby. I also have two drive controllers, a Dell Perc H310 and a Supermicro AOC-SASLP-MV8. Each of these draws around 10 watts on its own I've noticed.

So if I look somewhere around the 50W TDP mark I could expect something sub 30W on idle Quote Link to comment

So if I look somewhere around the 50W TDP mark I could expect something sub 30W on idle I haven't been following the discussion, but idle and TDP really have nothing to do with each other. TDP is a design spec that determines how much heat sink mass, airflow and overall heat rejection must be accounted for. Two processors from the same die family, one with limited TDP, both will idle at nearly identical power. The difference at full load will be significant, with the low power model throttled back to reduce the amount of work done so it doesn't need as much cooling. However, it will take much longer to complete the same task. During that time, the rest of the system will still be running at full power, so the net effect is that a low TDP processor may actually take more power over the long term with the tradeoff being much lower peak draw. Laptops are a good candidate for low TDP, servers, not so much. 1 Quote Link to comment

1812 Posted October 2, 2020 Share Posted October 2, 2020 I think I win... or lose... overnight "idle" low is about 217 watts. But it's never really at idle.That includes: 2 8 core processors (32 threads) 128 GB ram 5 disk main array in various states of spun up and down 7 disk backup pool spun down 2 SSD cache up 4 SSD pool up 1 vm running with 2 rx580's and some various dockers contributing to a few watts here and there.

pulpfxn Posted October 6, 2020 Share Posted October 6, 2020 System specs: M/B: Asus Z170-A CPU: Intel Core i7 7700 Memory: 16 GiB DDR4 Storage: 5x HDD, 1xSSD (Cache) Expansions: Dell H310 Parity check: 78-82W All HDDs spun down: approx. 50W S3 sleep (roughly 67% of the time, but can often stretch to 2-3 days): 16W (not sure how accurate my power meter is for sleep. I think it should be less) Don't use any dockers or VMs which need to be on 24/7. Via WOL, server wakes up and is ready to stream in about 20 seconds or so, which is good enough for me (my old N54L, which does not support S3, was closer to 3 minutes). Due to frequent power outages I have battery backup for the house, so every watt saved helps to extend battery life. To save more power I really should shut down the server more often, but it would take longer to start up and the drives would spin up on every start up (they remain idle when server resumes from sleep). Using a NUC to evaluate Home Assistant. Would probably keep using that (or similar) for home automation. @Morrtin thanks for your nice format. Quote Link to comment
Ranmacanada Posted October 18, 2020 Share Posted October 18, 2020 The UPS tells me I am at 164 watts, with an E5-2670 that has 14 drives. I also have the router and my switch on the same UPS, so my actual idle is lower. Quote Link to comment

Groy Posted January 13 Share Posted January 13 (edited) Hi I used to have a Dell 3050 micro i3 7100T with SSD and 20gb of ram as a server. 12w at idle. it's fast (at least for my needs), cheap if used, gigabit ethernet, 6 usb 3.0, ultra small, cool now a changed for a ryzen 3600 (I regreted with 60w+ at idle and not noticing signifcant performance except for videogames). the only downside is it's crappy UHD 630 graphics, maybe a problem with plex Edited January 13 by Groy grammar Quote Link to comment

SeeGee Posted February 14 Share Posted February 14 My idle power is 216w on dual Xeon e5-2690 v3 w/ GTX 970 for transcoding, a dozen spinners, 2 sata ssd and 3x nvme. I'd be interested in tips to help bring that down a bit more if possible. Good thing power is cheap where I live. Quote Link to comment

Alex.b Posted April 5 Share Posted April 5 Woww 8.5W. What is PSU ? With my old config (i5-4440, 16GB, 2x1Tb ssd), I’m at 22W average on idle. I know diff between 22w and 8.5w is about 20€ of electricity by year but I need to lower my power consumption. Thinking to change CPU and MB ! Quote Link to comment
aarontry Posted May 21 Share Posted May 21 I am idle around 150W. 2 x E5-2680v4 + 128GB ECC DDR4 + 1 10Gbps NIC + 6 HDD (1 active, 5 spindown) + 7 fans around 850 RPM on Supermicro X10DRi. Quote Link to comment
Surfparadise Posted July 16 Share Posted July 16 Hi all, I'm struggling to choose the right HDWR for my new unraid server. My objective is zero noise, lowest possible power consumption with plex transcoding capabilities and at least 8 threads for my VMs. I thought to found the right config with this: https://www.asrockind.com/en-gb/IMB-V1000 CPU (V1605B, 4C/8T, 2GHz, TPD 12-25W) - CPU mark 6876 !! The problem that I discovered that PLEX doesn't support HW AMD trascoding 😞 Now the problem is to find a right config to have a power consumption of about 15w in idle. Actually my idea is to use this: CPU i3-10100 / 10300 MB ASRock B560M-ITX/ac What do you think? Anyone have tested this cpu? Could be possible to limit the frequency and tune the undervolting setting to achieve this objective? Any suggestion? Thanks Quote Link to comment
Ver7o Posted July 25 Share Posted July 25 - G6400 - H410 itx - 2x4GB - nvme cache - R7 240 GPU - 1x120mm case fan which is always running My idle consumption is about 20-21W. Without the GPU its about 15-16W. Thats with everything unused turned off and bios tuned for power savings (eg. turned off wifi antennas, bluetooth, onboard sound, turned on pcie aspm...). I'm running the conservative cpu governor as it makes zero difference in power draw but a giant difference in overall speed.

Thanks I do not use Plex with transcoding, but if thats your objective even something like G5400/G6400 is plenty powerful for such task and might be closer to your power target then an i3.
