tempting will you be selling them.

M21 July batch listed.

Yeah this will be a bit harder to hook up than I thought.

https://www.tripplite.com/14.4kw-3-phase-metered-pdu-208v-outlets-36-c13-6-c19-3-l6-30r-hubbell-50a-cs8365c-6ft-cord-0u-vertical-taa~PDU3MV6H50A

might work if 208V, 24A per L6-30 outlet.

Probably be best to get the wire and plugs you need and make your own power cables.

the problem is the c19 end as it rates at 20/16 amps  this is borderline if you have  3 phase 208 voltage. fairly common or 210 volts single phase which is not common.

the 20 amp is short term and the 16 amp is constant.

3417/208 =  16.4278 amps    which exceeds  the  16amp 24/7/365 constant duty number.

clifton nj has never been under 217 volts  so we are at 3417/217 = 15.7465 amps  which is good.

the local solar array in howell  is 237 to 242 volts   so 3417/237 = 14.41 amps  that is pretty good.

So anyone getting a large order of these needs to watch for this  issue.

There are a few ways to make sure you stay close to the current amps.

https://www.larsonelectronics.com/product/222271/1-phase-buck-boost-step-down-transformer-240v-primary-229v-secondary-87-34-amps-50-60hz

the transformer above can be wired to boost  11 volts rather then drop 11 volts.

It is single phase.  it can do 83 amps at 240 volts.

But all of this is pretty much a mute point until we start testing them  out in various conditions.

We'd still be streaming if they sent us a unit.

Might work but close to $40 a cable.

Yeah about 19 hours in 69500gh and 3417 watts.

Power cable looks like a c19 12awg

So it is going to be touch and go to power this gear.

As 3417 watts is very close to max spare load. For that cable.

I may have to run these at lower then top speed.

We have had our volts drop to 216 in Clifton and go as high as 239 volts.

We mostly run at 227.

3417/216 = 15.819 amps. My cables are rated 20/16 amps. Ie 16 amps running 24/7/365

So that is really close for me 16 max 15.819 actual.

If you do less then 210 volts say 208. With my cables you are at

3417/208 = 16.427 amps  and that is over the rating of the cable.

I’m being diplomatic since I have not tested this gear, but I do not like what they did.
I prefer bitmain’s Two power cord solution on the s17 which I have tested.

I do have a source for an audio cable that can do better then the tripplite cables but they are not cheap.

You mean this?:

I see, pdu's i'm looking at for my 30A 240 line will have 3-4 20A outlets pending model. Thinking that should run them. But yes my current pdu only has 16A outlets.

Pango also have a youtube demo of the m20s though I can't find the tweet right now with the link.

My pdus are mostly hp 4 receptacles each one of the four are 15amp.

The main breaker on the pdu is for 30 amp

You can run about 25 amps on the four receptacles but 22 amps never trips while 25 sometimes trips..

Since the individual receptacles are 15 amp max they will not work with the m20s

This is another reason I ordered only one. Not 5 or 10.

I suspect many of us will not be using pdus with this gear.
I suspect we will go right from the wall receptacles to the units.

Another option but better suited for most pdu's.

I have been told the demo m20 will ship June 4 or June 5.I got a telegram from laurent today.
I could get it by Friday the 7th but I think it comes on Monday the 10th of June.
Exactly 1 month later then the may 10 date given.

As I said I plan for these delays accordingly. I source from multiple companies and sources.
I use PayPal when a seller allows it.

So  I should have the m20s soon and won't order any gear until then.
I have 2250 + 1880 + 1670 =  5800usd in undelivered gear
plus 3200usd in promised gear =  9000 usd which may cost me 2484usd in trump tax.
I can only take this much risk due to all the gear I already have mining.
Once some of this comes in I can access more moves.

but for now there is nothing for me to do but wait for the m20s.

I delayed getting a lot of them as I fear the power cord it appears that it may be very close to its rated numbers.
This may be a problem.

tripplite makes this cord

I think this cord will do the job barely.

If I had better access for testing this unit with this cord making an order of 5 or 10 units would have been easier to do.
the m20s does 3300 watts a 20 amp cord can do 16amps 24/7/365
so 16 x 230 = 3680 watts using the derated safe number. The cord should be good as 3680 is bigger then 3300,
but if volts drop to 220  then 220 x 16 = 3520 watts and if 3300 watts jumps 5% to 3465  it would be very close.

To me  having 10 m20s would be great if:

I know they are good gear
If I know the tripplite cables don't over heat.
If I get them in June
If I pay under 2500 usd each for them

none of that is certain for me..  So I have 1 coming not 5 or 10.

July batch is the soonest for m21s I believe and also remember manufacturers don't care about selling one or two units as much. Even some resellers for that matter. Maybe it's best to layer your buildout with multiple readiness in releases. You hashing some now will benefit you at market atm. Adding more later will as well. If your power rate is nice you'll be ok to good, if not your still hedging that BTC is trending up. Best to see what you can get now, pre order sparingly when opportunity is right as gear will only get more expensive and harder to get as market gains.

I would assume your power rate is high enough market volatility will play more of a factor. So if you're set on mining ease into it, more you absorb the better off you'll be. Sweet spot for gear recently has been Mar/Apr and a piece of May. Looks like Q3/Q4 will have more units out but again you risk higher pricing. Essentially control you FOMO, think what risks your willing to take and which you aren't.

I bought from them multiple machines with no issues.

That is really hard to answer.
But here goes I have order from them multiple times.
I would rate them as a B+ would have been an A-

But  they have been slow with  my m20s demo.
They were fast with 7 m10 orders.

Here is the deal asic sellers  that are not crooked  give better service when margins are tight for miners.  The give worse service when times are really good for miners.

The reason is pretty simple  selling gear when btc is 3200 back in dec of 2018 is really hard, but selling gear now in June of 2019 is pretty easy when coins are 8500 and the gear is more efficient then ever.

When I purchased my m20s coins were 4200 and I paid 0.50 btc  coins are hot that same coin now is worth 8500.  So buy and Hold  I would have 2x my value while I wait for the gear.

So if you buy 4 machines right now it is 10201 usd or 1.20 btc

you need to be able to analyze your risks.

First off pay with a bank transfer or newly purchased coins. There is a sound reason for this.  It will allow for hedging your risk.

So lets say you order the 4  with coins purchased today at 8500 price point. 1.20 btc for the 4  units.

first risk is  they never send the gear.  they have an okay track record so maybe it is not that high of a risk.
second risk they are slow.  Aug to Sept means a 60 day window. This allows them to have a 60 free hedge zone. this is not to your advantage.

if coins shoot up to 10k or 11k or 12k  they will not rush to ship and hit the late date sept 28 or so
if coins tank to 5k they will send a bit early  say aug 10  so you like them and may still buy more gear because you have a killer power deal.

You as a miner  have some defenses  against all of the above.
can you do the move below

a spend the 1.2 btc you purchased and get the 4 units.
b buy 1.2 btc hodl it
c put 10200 usd and hold it use it to buy coins if they drop down to 7500 6500 5500 4500  spend 25% at the 7500 level and so on.

if you can do all 3 above  it cost 30,600 usd. and you have leveled the price risk out via  a proper hedge technique.

It is  not that costly to lower the risk somewhat.

But all of the above assumes  you have cheap power and can deal with heat and noise of the gear.

Most of us don't hedge and get burned by guessing wrong.

I do not hedge like I just described above.
But I have 650 th online with 260th in future orders  my hedge is to buy from multiple companies and also use some brokers paying paypal.

My way I never make a perfect score but I never get crushed by 1 bad deal.

I have :

1 t15 due next week  used a broker paid paypal. Most people do not get to do paypal as they are not trusted
1 m20s demo due next week it is about 25 days late I paid in 0.50 in purchased  btc for it.
2 or 3 a1041's coming

1 inno t3t 39 due in july I paid .20 in purchased btc for it

I used coins valued at 8700 there was a price drop in coins to 8200 right after I paid for it I purchased .216 coins  for the same amount.

so  I am 0.016 btc ahead already on the inno deal

you may consider that move if you buy the m20s at 8500 and coins drop to 8000

I am thinking of ordering multiple M20S from pangolinminer.com. Anyone has any experience ordering from the website? It says that the shipout is late August and beginning of September but I am worried  about the actual delivery date, since each day of delay means a huge loss on my side.

Yeah.

they missed april 25 date  but that was quickly altered via dm before I ever paid coin in.

They missed may 10-may 20  set of dates.

They missed before June 1st date.

MY hope is  any date next week or June 3 to June 7.

In the meantime I got a hold of one t17 to ship next week for a premium price offordscott is doing that deal.

I also ordered 1 t3t39th from innosilicon due to ship in July.

So the wait is on.  A lot of gear to review I hope

Avalon a1041
bitmain t17
whatsminer m20s
Innosilicon t3t 39th

So far of all new gear

the bitmain s17pro 53th = mint gear would like more of them.  but short runtime maybe 2 weeks so far.

all the gear above and the m10 bury the s9.

I wonder what the relationship of the two resellers is? On the Pangolin site if you hover over the Facebook icon the link is https://www.facebook.com/whatsminer/   and the Pangolin tag on the FB page is @whatsminer.

I'm surprised we still have issues confirming whatsminer.net they have a thread in service discussion and I've properly linked them in the Competitive hardware thread. Have to find a better way to get the word out I guess.
On the note of these Demo's they had my interest peaked when I got the email asking if my customs form looked good, but no shipping yet that was 2 days ago I guess and they'll be done for the week now. They did update that they have received one at Pangolin on Telegram

Thank you, I have done a few buys from Scott with no issues.
