Antminer T17e is not powering

[chris1030]

Hey guys! can anyone help me about this. my antminer t17e is new and after a lots of problem with the electricity the miner goes power off. I try to open it again and it dont power on anymore. 1 fan on the power supply is running but the whole miner is dead. What should I do ?

Thanks in advance.

[philipma1957]

explain to us this statement

"after a lots of problem with the electricity"

did you have a blackout
did you have a brownout
did you have a power surge
did you have  rapid power on power off power on power off

that power supply needs around 205-240 volts for each plug
the  2 power cords need to be able to  give 10 amps of power to each plug

My thoughts are you are not feeding 2 cables with say 220 volts and say 9 amps to the unit.

if the power supply thinks 1 plug is dead  the miner does not turn on.

that is pretty easy to fix  simply make sure the 2 cables can feed the power in and they work.

3 bad case issues maybe be 1 of them 2 of them or all 3 of them

1) killed the psu with your electrical issues
2) killed the controller with your electrical issues
3) killed the hash boards with your electrical issues

All the new generation miners such as T17,T17e,T17+ and S17,S17+,S17pro require a stable voltage between 200v and 240v, anything below or above will burn the PSU or cause a partial damage to it. You did mention this

1 fan on the power supply is running

There is a good chance that you have burned 2 fans on the PSU, if you have another miner try to replace the two fans that don't spin and see if the miner will power on, if it does not - your PSU is dead.

also there could be some protection-mode in the PSU, if you don't feed it with 200v-240v it won't turn on,and thus the miner won't power on, so make sure you measure the voltage.

If non of the above works, then you will have to buy APW9+_14.5V-21V from Bitmian for 134$ + shipping.

A small video of you turning it on could be interesting. As everyone else said: What happened with the power?

[judypug1956]

[...]

to further elaborate on this if you put 240 volts into 1 plug and 205 volts from another plug

It could be a bad issue.

I feed my gear with

I get them at better prices but they work great with bitmain 2 plug gear.

Problems is:

1. The power cord is overheating
2. The extensions and wall plug is also heating
3. I tried to use AVR 3000w and plug both power cord to 220v but its still overheating

[...]

I also hoping that the psu protection-mode does that.

You need a Voltameter or a kill-a-watt tool, do not plug your miner in the latter unless the device can handle 3000w on 220-240v which is not very common, but that tool is good enough to measure the real time voltage, if it's less than 200v or above 240v then forget it, it can't run antminer T17 and you will need some sort of voltage regulator to be able to run your miner.

1. The power cord is overheating
2. The extensions and wall plug is also heating

They are heating because of two reasons

1-Low voltage
2-Wire size is not large enough to handle the current.

for point 2, it's not just about the wire that goes into the PSU, it's all the wires from the PSU to the grid, you need to give us more information about your infrastructure to help you better.

you can also use this wire size calculator to get an estimate of what wire you should use, generally the T17 draws about 15 amps on 200v and you will need a 16awg Copper or 12awg Aluminum for this setup.

[philipma1957]

Ahh  I have an AVR 3000W  and it simply does not have the testicles to run a t17e

ie   that is an under powered unit.

the t17e  pulls juice hard real hard about   3300 watts. It is   over spec on both of my units.

the avr 3000w    can supply about 2400watts

you have this correct?

https://www.ebay.com/itm/323593437551

BTW  even if the t17e ran true to form  and pulled 2850-2950 watts  it is too much for your unit.

Stop trying to pull a trailer with a kia forte.

Also what  is your wall outlet power ?

If you want to run a t17e

the wall outlet needs  to be 205-240 volts
it needs to be a 20amp breaker
it needs 12 gauge copper from the breaker to the outlet.

I will use this outlet

and plug the y-cable into your miner.

[chris1030]

Wall outllet is 220v, idk about the breaker. Also do you advice to use AVR ?

Thanks for this information tho.

[philipma1957]

The avr can not handle  the draw the t17e does.   Don't use it for the t17e.

do you have a photo of the 220v   outlet ?  If you do I can figure out what cabling for you to try.

[BitMaxz]

AVR is only good for PCs so not good if you use it for your miner.

Much better use the thick extension or plug the miner directly to wall outlet and test.

If it still not powering try to check your PSU remove cords from the control board and hashboard and run the PSU alone check the extension and wall outlet if it still hot while the PSU is running. If it's not hot your issue might be inside the miner maybe some parts are shorted(Maybe one of the hashboard has a loose heatsink that may touch to other parts) that leads to the power supply and extensions become hot.

If you have Multimeter (Digital or analog) better check them if your miner is shorted.

its a simple house plugs, also we will change the amp breaker to 20 and a lot of things to be fixed.

[philipma1957]

what country are you in?

are you usa and you have this plug?

https://www.lowes.com/pd/Hubbell-White-20-Amp-Duplex-Residential-Commercial-10-Pack-Outlet/1000049917

this is a 20 amp plug

if you have a 15 amp plug

https://www.lowes.com/pd/Legrand-White-15-Amp-Duplex-Tamper-Resistant-Residential-10-Pack-Outlet/3236646

it may need an upgrade.

If you are in a different country.  plugs will be different.

From Philippines.

Using voltage stabilizer is indeed a great idea technical wise, do not listen to anyone who says otherwise.

Economically, using those stabilizers might not be a great idea, so I will leave it this way.

You also did mention you had a AVR3000, notice that most of those devices are rated in VA (volt*Amps) which is not exactly Wattage, at best case scenario you are looking at a power factor of 20% so you have to multiply that 3000*0.8 and you get 2400w which is noway near what Antminer T17e needs, you will need at least 3600-4000VA.

also we will change the amp breaker to 20 and a lot of things to be fixed.

Changing the breaker won't fix the overheating issue, 20AMP MCB is the minimum safe size, however, just by replacing it - the wires won't run any cooler, you need to replace the wires from the 20amp breaker to the main breaker.

I think that's a 125 volt plug. I've found that a "20 amp rating" on a plug really means don't pull more than 75% or so non-stop. My electric car charging pulls 2.2kw at 240v for 10 hours and can make a 15a 240 volt socket a bit warm. For a 3400 watt load I'd go with this at the least with 12 gauge or better copper wire:

https://www.homedepot.com/p/Leviton-20-Amp-Commercial-Grade-Double-Pole-Single-Outlet-White-R52-05821-0WS/100356999

And a twist-lock version if this thing really pulls that much power and you want to make sure the plug will never wiggle out a bit.

Sounds like these T17's are like the S9's were: You "could" run an S9 on a 120 volt 15 amp circuit but it was right at the edge and would overheat the plug. 20a was doable but the best bet was to run them off 240 volts. For the T17's it's sounding like one "might" run it on 240v 15a but really the right way is with a 20 amp circuit.

And if you have 208v instead of 240 volts the current draw goes up a good bit. 3400/208 is 16.4 amps which is a bit more than I would put on a 20 amp circuit and plug.

Maybe it's time to just build 3 phase power supplies.

[Philipma1957cellphone]

OP is in the phillipines so I don't know how the wiring is by him. His internal wire could be 14 gauge he may have only 15 amp breaker and he may not.

He has the t17e model my two t17e units are very power hungry 3200 watts. I do not want him to hurt  his home.

[lightfoot]

Ah yes, the Philippines. You're right, they use weird stuff there. But at this level of power usage we're talking more "dryer" and less "cute home miner".

I've seen enough pictures of burned mining facilities and watched shorted miners explode to not want to see corners cut.

[Philipma1957cellphone]

yeah
the t17e
the m20s
The m21s all pull over 3000 watts.

I think the op's internal wire needs to be 12 gauge and the circuit breaker needs to be 20amp.
