(npub1u20β¦ds5s) Idle power for dual 6282 SE's and the mobo is ~60W according to lm-sensors.
Full load power is 280W+~20W for the mobo ;3, but that's somehow better than intel's recent housefires and consider that's 4 CPUs (2x dual 8 core die CPUs).
Idle power would probably be lower if Turbo 2 and power saving were actually properly configured, but it's noted that on tickless systems (nohz=on), the extra cores can enter CC6; https://www.coreboot.org/Board:asus/kgpe-d16
If power consumption is a big issue, I would recommend dual or a single 6278 or a 6262 HE if you can find one; https://en.wikipedia.org/wiki/List_of_AMD_Opteron_processors?useskin=monobook#Opteron_6200-series_%22Interlagos%22_(32_nm)
In my testing with a 6278 and 6282 SE running in the same motherboard (mixing and matching CPUs like that isn't meant to work, but it did) it seems the 6278 is the 6282 SE on a slightly newer node, but slightly less aggressively clocked, meaning it's a bit slower.
S3 ACPI is currently broken, but based GNUboot developers are working on fixing RAMinit, which will allow for resuming from suspend to work.
There's also the workstation equivalent KCMA-D8 with lower powered CPUs: https://www.gnu.org/software/gnuboot/web/docs/hardware/kcma-d8.html
Getting CPU coolers to fit on the KCMA-D8 is reportably easier and finding a case is easier too, but it just isn't as good.
