Handful of mostly-complete production verson pods undergoing some comparison testing. I'm testing VH's build updates while also trying to get some statistics on peak frequencies attainable at different voltage settings.

Nothing too important, just thought it was fun.

Also I'm updating the first post a bit with photos and info.

We are not retail.

Hopefully our builds are decent.

I think base should include the micro usb at minimum, brick secondary, and maybe our kit will set up for more pending electrical lines. But maybe 6 off a 110v? Regardless I think the vendors you already procure from will take care of your needs.

The high-end ATX generally have a single 12V rail that's piped to all the cables. I don't know that any of them have per-cable current limiting but if one did it'd be completely unsuitable for mining - even GPU mining. The 75W/150W spec is for PCIe compliance on the device end so the PSU is required to source that much as a minimum standard but a good one will be capable of quite a bit more.

Technically the 6-pin PCIe, to be in spec, only has to have power on two of the 12V lines. And the only difference between the 6-pin and 8-pin (6+2 commonly) is power guaranteed on the third line, plus two extra ground lines. But a good PSU will always have power on all three power lines even for a 6-pin.

Anyways, for this miner, if going over about 8A you'll want to use the 6-pin. Shouldn't be possible to get much over 10A draw out of it regardless.

PCIe spec for a 6-pin specifies a 75W draw. As anyone that's run any mining gear since at least 2013 will tell you, a good PSU will give you a heck of a lot more than that. Some ASIC miners will ask for up to 300W from a single 6-pin, which is why folks started turning to high-reliable server PSUs and durable aftermarket cables.

Or did you think the S9 needed 20 jacks?

My pod's barrel connector is rated for more than 75W. The miner's internally limited to much less power than the 6-pin could provide (from a good supply).

I've run a bunch of different mining gear but only since 2014 and I learned something new today. I'm running my S9 on an Endermax 1800 with the 6+2 PCIe, just not using the extra 2 wires. I thought that to get 150 watts, you needed a 6+2 even if just using 6 and not the +2. I bought extra 6+2 cords, when I might have gotten away with the 6's. Although the wire gauge might not have been the same? However, I guess PSUs differ and of course I was assuming the spec is reality, which is not the case. Obviously you can wire up whatever you want as well but I'm usually not hacking together PSUs like you probably do.

I don't know what additional specifics resellers will offer for packages, but everyone should have at least the base option of a quality 8A power brick. That'd serve you pretty well unless you wanted either more efficiency for running a stack of units, or to max the overclock of a single unit.

Can't wait to do 2Tb with my 20 Newpacs and this unit about 250watts or so?

I have setup 2 200watt solar panels and 200ah battery in my shed, I will be using solar to mine

This sounds awesome. Doing this off solar or wind has always been a fascination of mine. You mind sharing the equipment you use and how you set it all up?

Along the lines of discussion above, will any of the resellers be able to provide power supplies?

I've always used USB ports and DC adapters because it's easy and I'm a dunce. Sounds like these will force me to up my game a bit.

I trusted the 16AWG cables I manufactured to handle 8A per wire for 288W total on a 12V system.

The internal Vcore regulator on this pod is limited to 20A at a peak of about 5.5 volts for 110W total. Add in peripherals, inefficiency and the fan and you should never need more than about 10A of 12V for this guy.

Linux since 1997 RedHat 4

Cables are rated in Amps, not Watts.

A typical, single core, 16 gauge wire is usually max rated at 15 Amps (times miner 12V) = 180 Watts
and 18 gauge at 9.5 Amps x 12V = 114 Watts

A PSU PCI-e connector usually has 3 wires so can deliver 3 times that per cable.

But the limits can be the connectors, which usually are hard to find out what their specs are.
(the cables are a lot easier coz they usually say their AWG on them)

You are getting mistaken. the PCIe slot on a mobo is 75w the 6Pin PCIe Cable can handle 150w give or take a few (possibly more if someone wants to confirm).

A lot depends on cable gauge say

20ga = 75-100 watts.
18ga = 125-150 watts.
16ga = 175-200 watts.

note not official numbers.

mostly based on 7 years of mining using various cables.

gt_addict is correct, the cables and the connector on the pod themselves are rated at 13A and are run off a external power supply. In sidehacks case, a configurable power source so he can monitor the raw power usage, others use a break out board and a HP common slot power supply, or just a standard PC power supply with decent power ratings. just make sure your using 16 gauge wires.

heres an example of the powersupply/breakout board kit

In the photos, it looks like Sidehack is running it off a 6 pin PCIe connector which would be 75 watts max.

A forum member is shipping five sticks to me this means we will have nine compacs in the raffle.

I think I will do two raffles one for North American orders from any dealer that is sidehack approved

And one from Europe from any dealer that is sidehack approved.

Six sticks in the North American raffle. Three sticks in the european raffle.

I will need to check them all out to see how they run. I will need to figure a way to do it all should be easy enough.

Ideally i would do the same but weather is just too hit or miss in the UK.

It seems you've beaten me to it. I'm not one for complaining about function over form, but the first pictures you put (I know it is a work in progress Wink

) could've done with some colour Grin

Needless to say ALL of your gear (and VH's cgminer) have always been, hands down, the best gear ive owned.

I'm still finishing the details but it'll have a sweet logo and the jacks will be labeled. Nothing that can't be undone, of course. And have I ever built a thing that can't be disassembled? I wouldn't do that to you guys. Or myself, frankly, because then warranty work would suck.

I can't wait to get my hands on this one

They should work with Cgminer like Newpacs just connect and done?

Can you put one on Youtube working ?
