Indeed, that box here next to my desk draws 50W of electricity continuously despite being mostly idle. Why? Because it has ECC.
Having some affordable low power device with ECC would be a game changer for me.
I added affordable to exclude expensive (and noisy) workstation class laptops with ECC RAM.

- nsteel 4y ago> Why? Because it has ECC Sorry if I am missing the obvious here, but why would ECC consume so much power?
- growse 4y agoIt's not that ECC consumes power, it's that systems that support ECC tend to consume more idle power (because they're larger etc.)
- Maakuth 4y agoThere are Intel Atom CPUs that support ECC. I had a Supermicro motherboard with a quad core part like that and I used it as a NAS. It was not that fast, but the power consumption was very low.
- smartbit 4y agoDo you remember how many Watts it was using with idle disks?
- Maakuth 4y agoIt was this board: https://www.supermicro.com/en/products/motherboard/a2sdi-2c-hln4f https://www.supermicro.com/en/products/motherboard/a2sdi-2c-... I think it was idling at something like 30-40W with four HDDs and a UPS. I didn't have an especially efficient PSU and the UPS must have taken some power too. The motherboard alone would draw as little as 15W, I suppose.

The CPU mostly goes in 1L ultra SFF systems. TDP is 35W, and under stress testing the CPU tops out around around 38.8-39W. The onboard BMC is about 3.2-3.3W of power consumption itself. Most data ingest and reads comes from the SSD cache, with that being more around 60W for high throughput. Under very high loads (saturating the 40Gbps link) with all disks going, only hits about 110-120W. By comparison, a 6-bay Synology was over double that idle power consumption, and couldn’t come close to that throughput.
- sys42590 4y agothanks for the parts list, especially because I think ASRock Rack paired with a Ryzen Pro offers better performance than a Supermicro in the same price range.
- MrFoof 4y agoThere’s reasons for that though. I could drop a few more watts if ASRock could put together a decent BIOS where disabling things actually disables things. SuperMicro costs what it does for a reason. —- ————- If you’re looking for a chassis, I’m using a SilverStone RM21-308, with a Noctua NH-L9a-AM4 cooler, and cut some SilverStone sound deadening foam for the top panel of the 2U chassis. Aside from disks clicking, it’s silent, runs hilariously cool (I 3D printed chipset and HBA fan mounts at a local library) and it’s more usable storage, higher performance (saturates 40Gbps trivially) and lower power consumption than anything any YouTuber has come remotely close to. That server basically lets me have everything else in my rack not care much about storage, because the storage server handles it like a champ. I really considered doing a video series on it, but I’m too old to want to deal with the peanut gallery of YouTube comments.
- namibj 4y agoMost AMD desktop platforms support ECC, and if you don't use overclocking facilities, they are pretty efficient (though their chiplet architecture causes idle power draw to be a good fraction of active power draw, still much less than 50W though).
- stordoff 4y agoHow much RAM is that with? My home server idles at ~25-27W, but that's with only 16GB (EEC DDR4). However, throwing in an extra 16GB as a test didn't measurably change the reading.
