FYI, the seller will ship to the USA if you email them. Shipping costs are kinda high though. I bought three units with the intent of keeping one and selling the other two. I'm doing firmware and BIOS upgrades on all three, and also doing some basic burn-in testing on them.

I'm halfway through testing of the second board, so far, everything just works as expected. These do seem to be surprisingly power efficient. My on-desk test setup:
  • Gigabyte MC12-LE0 motherboard
  • AMD Ryzen 7 5700x CPU
  • 4x32GB ECC UDIMM Crucial MTA18ASF4G72AZ-3G2R OR 2x16GB ECC UDIMM Kingston 9965669-008.A03G
  • Noctua NH-U9S cooler w/92mm fan
  • Seasonic Focus SGX-500 80+ Gold SFX-L PSU
  • Intel 320-series 80GB SATA SSD
  • Proxmox 8.2 stock install
  • One network cable attached to IPMI interface and a second attached to one of the on-board NICs
I am using a Kill-a-Watt meter for measuring power consumption, so these are unlikely to be precise numbers, but it seems similar to what others have posted. So this is "from the wall", i.e. total system power consumption.

At idle, power consumption seems to settle around 20-24 Watts. Surprisingly, the amount of RAM (128GB vs 32GB) did not seem to make much difference in power draw. I did similar testing a long time ago with a different board+CPU, but with RDIMMs, and it seems those are very power-hungry.

The first board I tested was with the 128GB of RAM. I ran over 24 hours of memtest86 with no errors. I then ran 12 or so hours of prime95 (also without issue). The second board did 12 hours of memtest86 and just started the prime95 test, so far so good.

I also have a picoPSU-160-xt and a 192 Watt 12v DC brick that I want to try with this, to see how its efficiency compares to the Seasonic.

If anyone is interested in taking one or two of the spares off my hands (when testing is done), feel free to PM me.

I will be super interested to see comparison of supersonic Vs Pico on idle and load. :)

Quick follow-up to my previous post regarding power consumption. Using the config mentioned in post #361 (the 32GB RAM profile), I did four tests: idle vs prime95, picoPSU vs Seasonic. I let the system run for about 12 hours in each profile, and took the total watt-hours divided by total hours to get average wattage over the measurement time. Results:
  • Seasonic Focus SGX-500 idle: 19.7 Watts
  • Seasonic Focus SGX-500 prime95: 104.2 Watts
  • PicoPSU-160-XT idle: 18.1 Watts
  • PicoPSU-160-XT idle: 106.4 Watts

So, Seasonic is slightly more efficient at load, and PicoPSU is slightly more efficient at idle. But in reality I'd call it a wash, given that my measurement tool (Kill-a-Watt) probably isn't that precise anyway.

Note that I ran the prime95 "Blend" test, which isn't fully cooking the CPU all the time. Just randomly glancing at the Kill-a-Watt while p95 was running, I'd often see 125 Watt readings.

Also, the big determinant of PicoPSU efficiency is the AC-DC 12V adapter that is used (as the 12V line is just passthrough on the Pico). Here I used the Mini-Box.com PWR-ACDC-12V-16A-192W (Model ATS200T-P120) adapter.

Although I couldn't watch it the whole time, the few times I spot-checked my test setup, I never saw the Seasonic's fan spin up.

What power supply? How was the loading done? Any other peripherals attached (fans, drives, SSD, GPU, etc)?
