Discuss Which power cable do I use with a 1400w power supply? in the Electrical Forum area at ElectriciansForums.net

Hi,
I bought a Bitmain Z11 ASIC miner and it is not supplied with the power cable and unfortunately I have minimal electrical qaulifications.
The power supply for this machine is 1400 watts, has an input voltage of 176-264v 50/60Hz and is rated 15A MAX. Output is 12V - 115A MAX
I thought about buying a C13 power cable with a 13amp fuse but I'm not 100% sure. I can't afford starting a fire and don't want to break the machine.
So I would be grateful if any electricians out there could let me know exactly which cable I should buy?

Does it have a connection socket or is it hard wired?
You will need 1.5mm flex..
I would go for a 5a fuse to start with..
My reason being is that I wouldn’t trust that device with a 13a fuse.
(Who knows what they would get up to) ;)
Do you have any old iec leads knocking about?
 
just because it says 1400 doesn't mean it is always 1400 !
That is the maximum figure, in reality it is probably much less,
What is it powering ?

Blimey, does mining bitcoins use that energy? Why don’t you hire a 1.5 tonne digger from Jewsons and buy the diesel when you need it :)

Home mining has for some years been complete folly, where you will spend more on electricity than the value of the 1/10,000th of a Bitcoin you will occasionally mine. When it reached this tipping point, was when buying a share in a mining contract became a more popular alternative. Whilst these home devices are still sold online, they will always result in disappointment and a large electricity bill (often for the parents).

Google 'bitcoin mine' and look at the images of the multi-MW server farms that now exist, with state of the art processing power. The whole industry is at odds with the objective to become carbon neutral - see this chart.

Apparently, alternative investment of larger amounts of electricity consumption at home may still yield good profitability!

I'm afraid what you have,there,is the modern equivalent,of the goose which laid a golden egg.....only instead of a goose,it's a Chinese supplier...and instead of an egg,it's poop. :)

The units specs are here. It states use a standard IEC lead, current draw is less than or equal to 10A so a decent 13A IEC lead will be fine.

Thanks for all your replies. I have a 10amp cable but it is meant for use with the tv. It isn't hard wired no.
It is still profitable, believe it or not, as this machine, the z11, mines the equihash algorithm at 135ksols/s. BUT for how long I don't know.
I think i will have to wait til monday when the supplier can get back to me. I'd go with freddo probably being correct though.

Yes these power supplies use a regular IEC C13 cable. A 1.0mm² / 10A rated type should be used.

just because it says 1400 doesn't mean it is always 1400 !
In this case it is. You switch it on, it connects to the network and off it goes with the power meter at a steady maximum. If it ain't using the juice, it ain't earning the coin.

Well, it depends whether you were going to use the electricity for heating anyway. Compared to a miner, a resistive heating element seems a bit daft. It just converts electrical energy to heat without doing any compuation or generating any revenue. This is where home mining scores over large farms - they might get cheaper leccy and have more efficient miners, but they can't use the heat so that all represents loss. When you have a cold warehouse with no gas supply, the heat is fully utilised for part of the year at least so all mining work is profit once the miners are paid for.

The challenge is to encourage people to do more crypto transactions in the winter.

Only bit coins I’ve come across belonged to a drug dealer. Just over £1million confiscated just at the time the value had peaked. :cool:
