Nice story, but I don't know if I should believe a Newbie with one post.
What's not to believe in his post? That he got the unit earlier? This was already stated by me too and by some other members. That Spondoolies Tech was very helpful and prompt? Anything else?
Of course I hope the best with Spondoolies and really want to count on them to be a truly honest and moral company but now the home miners need to have a lot more capital or other funding otherwise or DC hosting as normal houses will not be able to run even 1 Neptune or one SP30 without major upgrades to 220-240v. At that point, heat is a large issue, normal house AC will not be able to handle all the heat.
Spondoolies said they are trying to get a good DC deal for their customers so they already got that covered.
I saw that about the DC but I was specifically referring to people who may want to run this at home and do decide to get more than a couple. As of now the 110-120v circuit on 20 amps (normal for house setups) will only work for 2 SP10s as that is over 2000w and 120v*20amps=2400w, so since most circuits service a whole room then you also have to be careful as anything else plugged in will be enough to trip your breaker.
Same deal with the heat, HVAC in homes are not made to handle that much heat, so you will have to install some more AC or a whole house fan, for the noise you have to consider noise proofing. If it is in a common area like the living room you will most likely have to enclose the area. I plan to do it with Plexi, like a small studio room but engineered for sound proofing and optimal air flow.
I have 3 45u racks single frame lifted above the floor by 8" and the 3 racks are about side to side, I had the electricians upgrade my house to 200amp and then run 0awg to a service panel right on the side of the wall where my racks are with a 125amp breaker and I filled that panel with 2 pole 20amp breakers. This gives me 6 240 outlets as my living room is close enough to the main breaker box that there is no voltage drop.
This gives me 240v*100amp=24,000w. With all my miners and the 4 SP10s I am pulling just over 10Kw, before this I had 10 Ant S1s, 6 Jupiters, 3 60Gh BFL + 4 Jallys (those are being used as a door stop at the moment).
So, I have barely used half of my available power and there are a lot of things that actually work on 220-240 as well as 120, most wall warts and laptop chargers work with both, PSUs actually are more efficient at 240v, in fact I find that most of my electronics that work at 240 are more efficient. I have not tested plugging in my plasma TV into the 240 but I bet it would work, just don't want to test it at this point
. Many things that don't even say they are rated to work at 240 do work at 240 and things like PSUs and from the looks at my plasma tv power board it converts the power to 240 before doing DC-DC to the rest of the components. Using 240v skips the power loss in that process.
Before the SP10s were installed the living room was pretty much quiet, unless you were sitting next to the rack the sound DB was lower than 60 and with the low pitch of larger fans it is not as noticeable. No issues watching TV.
Now that things are starting to heat up plus the heat from the SP10s the whole room plus kitchen is over 80f, my AC is on 100%, I will be installing a whole house fan that can pull over 7,000cfm right above the rack area and enclose it ASAP, before things get any hotter.
The electrician install cost $2k including permits, utility co upgrading my box, new main box and another breaker box for the 240. This way my living room is at the normal 120v but my miners are all at 240v, plus what ever I get an ich to test on 240
...
My racks are mounted on a 5x6 piece of plywood, raised with a 4x4 and 2x4 on top of that, I plan to drill holes so that air can be pulled in from the bottom.
There will be plenty of power once my other miners come but it's the heat and noise that will have to be dealt with.
Even if I were to host it at a DC the issue will be if that DC can handle the heat, these put out more heat than many servers and other rack mount devices and DCs are built to be cold but are made for hosting servers not really hot 100% running miners, I would be interested to see what the temp is for a server rack with just the SP10s filled to the max.
Then that also brings back the issue, I have already spent the money to host over 2Kw of miners and others may have done the same. Also, even though Spoldoolies is trying to get a good deal for hosting in WA they said that was for over 50 machines. Not quite something for the average miner, even the ones with a hundred g to spend.
So, point is that these do get hot and for people with 1 or 2 they may not be able to cool it adequately and not everyone wants to host their miners.
