also, what I'm seeing here is that the mobo itself only draws about 20 watts, is that correct? I was wondering how much the motherboards would add to the equation, seems to be that it's very small in comparison.
the cpu if it is a t variant is lowest power of the cpus.
intel g3900t
https://ark.intel.com/content/www/us/en/ark/products/90738/intel-celeron-processor-g3900t-2m-cache-2-60-ghz.htmltdp is 35watts
intel g3900
https://www.intel.com/content/www/us/en/products/processors/celeron/g3900.htmlhas a tdp of 51 watts
intel g4400t tdp of 35 watts
https://ark.intel.com/content/www/us/en/ark/products/90614/intel-pentium-processor-g4400t-3m-cache-2-90-ghz.htmlintel 4900t tdp of 35 watts
https://ark.intel.com/content/www/us/en/ark/products/129952/intel-celeron-g4900t-processor-2m-cache-2-90-ghz.htmlso using a t version saves watts ,drawback is if you want to run a huge rig say 8 3060ti's
you may need a better cpu.
Also bronze, silver, gold platinum, titanium psu.,
at a 500 watt build drawing a constant 500 watts.
bronze 625 at the kwatt
titanium 525 at the kwatt
also mobo efficiency
also the card itself and I am back to topic I have a 3 fan aorus 3060ti smos says I do
60.84 mh at 119 watts the 3060ti aorus
94.29 mh at 219 watts the 3080 evga
that adds to 318 watts for gpu
it estimates my total consumption is 378 watts
I have an FSP 1200 watt platinum
I have a intel g4400t
I use a stick of samung ram with this board
https://www.amazon.com/ONDA-B250BTC-D8P-Mining-Motherboard-LGA1151/dp/B0791Z44YXnow I run on the kwatt meter at 397-401 watts. i also know this meter has always been 5% hot. I have other kwatt meters that real less.
for fun I will run this 2 card rig with just the 3080 and see how much we drop.
So on the reboot.
I read 219 for the gpu via smos
I read 259 for the rig via smos
I read 269 for the rig via kwatt
so I dropped 378 to 259 = 119 watts via smos reading
I dropped 398 to 269 = 129 watts via kwatt reading
since the meter on the house counts I would use 129 watts for 60.84 for my card. hoping that the hot meter is maybe 5 or 6 watts higher then my house meter.
so the house meter is charging me maybe 123 to 130 watts for the card. it is hard to know how accurate the house meter really is compared to the kwatt meter. For me to do it correctly I need to have my wife out of the house for at least 4 days and only run 1 circuit in the whole house to test properly. Which is not going to happen.
