ANTMINER S4+ Discussion and Support Thread

[bitsolutions]

The included PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage.

Does this mean a Home in the USA can not use this as its only 110 service?

That's exactly what it means.  Unless you've got your home wired with some double pole breakers that'll give you the 240V, this product is not for you.

Aren't American Dryers 220v?

Good luck convincing the little lady that she's got to hang your clothes out to dry because you're replacing her dryer with some miners .

Electric Stove is also 220... Whats the connectors for 220v to the back of a S4+??? L6-30P to C13 Right?

Yes, so you might soften the blow by telling her she no longer needs to cook anything.

The point is, the double pole breakers you've already got in your panel are already being used for other purposes: stove/range, dryer, central AC, etc.  Virtually every other circuit you've got in your box is a standard 120V single pole.  To use an S4+ at home, you're either going to have to do something silly like replace your appliances with miners or install a dedicated circuit or two (and likely get your total amperage increased to handle the additional load).

How many amps is a 1500w Miner going to pull on a 220/240v Circuit?? my math says like 6.25... thats nothing

 (meaning I can safely run 3 S4+ on a single 20A 220)

If your house is wired with 12 gauge wire and you are using 120 volts on a 20 amp breaker you should be pushing about 1900 watts on that circuit
@ 240 volts on the same set up about 3800 watts
Do not use 14 guage wire for this set up if the breaker doesn't go you will burn down you house and electrical fires are harder to put out.

6.82A on 220v 6.25A on 240v and 7.21A on 208v(common 3-phase commercial voltage in the US).

Basically for any circuit you don't want to be above 80% load, so you could calculate the useable watts on a circuit by multiplying circuit breaker amps times the line voltage times .8 .

If you are pushing a circuit close to capacity you should make sure you know the voltage is correct as there is a difference in available watts between the voltages, for example on a 30 amp circuit with 3 S4+'s you would have 492 watts left over at 208v 780 watts left over at 220v and 1260 watts left over at 240v using a standard 80% load calculation.

correct sir thats why when i posted the wattage i post marginally below 80% so there would be no surprises.

Got a S4+ today, new in box. But it doesn't power up (no leds flashing, no fans, nothing)... I am in Switzerland, so it's 220V and they say it should work if higher than 205V....

Any suggestions?

Thanks

Try to open the case & tighten all of cable connection

From the PSU guide for no PSU fan and no output:

1.   Make sure the AC input wire has a good connection and the plugs are connected firmly
2.   Make sure the mains power is working well and its voltage is above 205V.

[supertee]

Power is all fine, can connect it to servers and they immediately power up. Will open it and have a look at it as soon as I am back at the datacenter. Thanks!

First of all, sorry for the large pictures.. 

Alright, opened it up and I am a bit shocked about build quality...

Spare (sharp) aluminium parts lyhing around in middle of the cables...


So I did some messuring, definately an issue with the PSU. I opened it up and and it was clear why it's not working...


I mean, really!?

Fixed the cable, no it's working... Actually things like that can be dangerous...

[Evan]

For anyone that cares I will be offering a S4/S4+ Water block, and Kit in the coming weeks I just need to get the engineering sample.

Let me know if anyone wants in I'll have 100% pricing with in 2 weeks.

[dimke_yu]

Sure if it is priced reasonably...

In the future you can post small pictures with the below code:

Wow, lucky it's didn't explode or damage the miner  
The 12VDC is short to ground.

[supertee]

That doesn't doo anything, but it the splitter could have done worse damage..

I am curious to know. What is the "normal" temp while hashing for this S4+ ? I can't find this information.

See the graph in https://bitcointalk.org/index.php?topic=1035629. 70-80C is considered normal for S4s, cutoff is 95C.

printscreen with temparature right now, it's running in our datacenter.

Oh nice, you could slap on 225 reasonably easily then as W/GH goes up nearly linearly. [Note that's near the limit of the PSU, and WILL void your warranty].

[supertee]

I just bought one to have a look at it and play around, might test that, too. I like the fact that you (normally^^) don't have to mess around with psu's.. For now it looks ok, as Spondoolies seems not to sell at the moment, I will get some more of those S4+ 

Will post another pic when it's a bit higher.

[supertee]

btw: it would be great if it was possible to restrict ui access, I only want the miner to be accessible from one (or more) ips... would appreciate if bitmain tech could add this feature in a future firmware upgrade

I think changing the password works just as good.  I would do that in mean time.

I could see a point to your suggestion, although I think it is something very few would use.

[supertee]

of course I changed the password. Each miner has a public ip, it's just simpler in a datacenter environment. So for me this feature would be a huge benefit.
