Topic: Ark Customized Version Of The A1 Chip Bitcoin Miner 1.5T ( low power consumption (Read 3671 times)

I think it could possibly be that some words are from another miner.  This looks and has same performance of the LKETC 1.5 T machine they made.

I wonder if it's really a "Ark Customized" or a LKETC made machine.

No offense but was this Google translated?  On first read I thought you might be from Texas, ore mining really?
Can't blame them on trying to use up all their old chips.  Was a price stated in there somewhere?

This PSU would replace it and be a upgrade.  Assuming stock freq it should pull around 1100 watts.   So a 1250 or 1300 would do it no issues.

I don't like doing it but you can use two power supplies.  I did this one a 1T dragon when it's original PSU quit.  One hooked up to a few blades and controller board.  And one just blades.  Worked for month's.  

I don't think you will find a way around not having power it if it's the board I'm thinking of.

you do not need that psu.  looks like an evga 1300 g2 can replace it.

 the evga 1300 supplies up to 1250 watts no worries.

It  has six pcie connectors.

what part of the world are you in?

If you can take a picture of the connector we can try and work out the pinout, and so a suitable replacement.

I bought one of these from a Chinese reseller on Alibaba.  The power supply died and I can't find a replacement anywhere.  The P/S has no 24 pin connector.  Just a 8-pin to the PCB and then 6 6-pin connectors to the mining boards.  Now that selling miners is hard my reseller stopped offering them and won't respond to me.  I need to buy a replacement power supply jst like the one in the picture.  Can anyone point me in the right direction?

There is no way PSU @ 90+ percent load to be so efective.
Also what settings your run A1 chips ( clock /voltage) in order to get 0.76 W/Ghs ?

There is no guarantee.

My 1150w power is boken.

Answer from 被遗忘者 [email protected] is:

"You can go to buy a local 1150 w power for replacement ，Even more so that you save money"

 

The Ark Customed 1.5T miner in large stock!

This is 6 module. 5 module can overclocking.
And our this miner can enough reach 1500G/HS. You can try to use 1.5T, it is not worse than 1T.

This is The Ark customed version, the light is red . the Power consumption is 1127w.

bro tak cukup power lah . . . add psu = more weight + increased shipping costs

opieum2:

With these 1.5T they're packing in more chips and not overclocking it.

Previously with the 1 th they're only packing 32 chips and overclocking it hence reducing power efficiency.

To remain competitive while continuing to use A1 chips, they pack 60 A1s and then don't overclock it or only overclock it slightly hence achieving the higher efficiency.

All the major A1 vendors in China are doing this.

These look remarkably similar to the AMT ones reviewed here https://bitcointalksearch.org/topic/amt-12ths-miner-first-impressionsreview-wip-752116, the only difference is in the PCB color. The fans seem just as loud. Can you post a video of the actual power consumption while hashing? Also the fact that that AMT also admitted they would sell via various fronts, its hard to believe these are different from the ones being sold now. Please post more info. Considering the consumption of the A1 the power consumption by itself is very hard to believe. Maybe there is someone respected and trusted in the community who can lend more technical insight on this.

Under the current caculate power soaring, mining more and more difficult. Under the Bitcoin market deteriorating situation , Bitcoin mining machine not to the past, to fight at all costs to calculate the force , now have to fight price-performance , mainly shows on single G power consumption. End of life in the mining machine to dig out the difference between currency and electricity. When the difference is 0 , mining machines have shut down, so power consumption indirectly reflect the life of the mining machine . 1T machine such as a daily output of 0.018 coins, electricity 24 degree a day, a half- count force 1.5T, producing coins .027 , electricity 36 degrees one day , when the currency * 0.027 < 36 * electricity prices, the mining machine on there is no need to continue to go on a dig ;If the force is also considered a low -power 1.5T mining machine , the same yield 0.027 coins every day, but power is reduced to 1100W, electricity 26.4 degrees one day , saving 10 degrees , apparently low-power mining machine life to be longer , for under the mining machine for the buck in a down- state work , physical life is certainly longer , at the same time stability will be strengthened. The evaluation of the mining machine for Ark customized version of A1 Minerals 1.5T ( low power consumption ) , due to the limited testing time , the measured data will inevitably be one-sided , welcome ore Friends correction.

1, The mining machine appearance and workmanship
Mining machine size slightly higher than the four- module A1 Minerals , dimensions: length 36cm*wide 17.5cm* high 46cm; total weight : 15.5KG. Overall mining machine shown in Figure 1 .
