Hello everyone, dear friends. Glad to see you! Today I will show you some of the best (in my opinion) mining hardware, with which work will either become easier or your income will increase. Here I will only touch on video cards, power supplies and motherboards.
And yes, I know that now it is no longer advisable to enter mining, because. prices for everything related to mining have at least doubled. And yet, sooner or later it will end, besides, everything that I write in this article will cost less in some stores than in others. In general - let's go!
Take two power supplies
Since the cost of one block per kilowatt is approaching the space cost, blocks are now taken into the farms in pairs. They work together with the help of a synchronizer, which, in principle, can be assembled by yourself, but why, if the Chinese product will cost 200-300 rubles.
This can be bought for 150 rubles, there is nothing tricky about the device
What am I talking about? Now it is more profitable to take two 500-watt power supplies than one unit per kilowatt. It is more profitable to take two at 750, rather than one at 1500, and so on, you get the point.
The block looks good, such a place in some gaming computer ... No, not a healthy person, but a miner
Efficiency, the filling of the unit, as well as connectors for connecting video cards and the distance between them are important to us. CoolerMaster MWE Gold Full-Modular 750W power supplies, which I mentioned in a previous article, are quite suitable for our tasks.
Cooler Master MWE Gold 750 V2 Full Modular 750W Power Supply (MPE-7501-AFAAG)
- Form Factor: ATX
- Power: 750 W
- Efficiency Standard: 80 PLUS Gold
From the pleasant - two cables for video cards, each of which has two 6 + 2 Pins. At the same time, the distance between the connectors on the cable is 12 cm, and the cables themselves are 60 cm long. The blocks are modular, but this, in my opinion, is not so important.
At the same time, these blocks have a gold certificate, which means that we will not pay for the heat that is generated from the rest of the efficiency in the power supply (such a joke, I know that jokes are not always understood the way I think). In short, a certificate in a farm is a necessary thing, not so much for saving energy, but for at least some unloading of the network, where, when consuming 1000 watts, there is a difference between the conventional 80 and 90% efficiency.
The insides of this block
Also, do not forget that this block has a range of protections, operates in the voltage range from 100 to 240, some of the conders are polymer, the rest are elite (not the best conders, but in my experience they are normal). These blocks also have an alternative - the White series of the same CoolerMaster, which has lower efficiency (a regular certificate, not even bronze), and wires are not modular, but they are cheaper.
There are different motherboards for mining, but some are just a regular board with a huge number of PCIE slots, without any different technologies that make life easier for miners.
ASRock H110 Pro BTC+ is a good motherboard for those who are going to mine. Why she? After all, other manufacturers also have motherboards that were cheaper in normal times, but at the same time they were not inferior in terms of "chips"? I answer - do you think we live in normal times now?)
There is even an M.2 slot
Seriously, I tried to find at least some mining boards in my city for + -10K, but nowhere, I emphasize - there were no non-ASRock models ANYWHERE. The company has made a certain bet on mining, so they have stupidly more boards for this task, and they are produced in a larger circulation than other companies.
As for the board itself - a typical mining board. The board itself has a pair of MOLEX connectors that are needed to power the PCIE X1 slots.
Such a photo "chip"
The board has 13 PCIE slots, 12 X1 slots and a single "full-fledged" X16. The board also has power/reset buttons (which is sometimes lacking in motherboards for users of the middle price segment), judging by the information on the website, there is a special “hardened” textolite and a slightly increased thickness of the tracks – all for reliability.
ASRock H110 Pro BTC + motherboard
- Form Factor: ATX
- Socket: LGA1151
- Memory: 2 x DDR4 DIMM (2133-2400 MHz)
This board is frankly inferior to the board from MSi, which I saw quite recently, but A: I have a lot of questions about MSi products (in particular, engineers), B: in January this board cost 13K rubles, that is, the last board went for 14 -15K+ (ASRock can actually be found for 10), and Q: this is practically the only board, of which there were many, which are now in stock and which you can buy.
And finally - video cards
Video cards for mining are an object of controversy and controversy, since in addition to the “dry” profitability figures (namely, profitability, that is, income minus electricity), you also need to take into account the fact that AMD cards are sewn, that Nvidia can be downvoted directly from under Windows, which someone it does not work and so on and so forth.
In general, we will consider both for the “experienced” miner, and from the point of view of “yy, I want to mine, where to download the video card”. So:
There are practically no interesting video cards on the market for a miner
That is, not just “no”, but “savsem net”. Throwing out 250K for RX6900XT is such a pleasure, as well as laying out about the same amount for 3090. You have to come to terms with the fact that an experienced miner needs to look towards used video cards.
Market, what's wrong with you ?! You feel bad?!
And here on the market there is RX470/570/480/580/590 8Gb. What's the catch, and why so many? Yes, everything is simple - in terms of profitability, this is essentially the same card!) The difference between the RX 470 8 Gb and RX 590 8Gb (there are no others in nature) is imperceptible in profitability, and judging by the nicehash calculator, it is generally equal to the error (in practice , most likely it is).
At the same time, they do not have much difference in price, but more powerful RXs can be sold at a higher price in the future, so it makes sense to buy more powerful cards, unless, of course, you are going to use them exclusively for permanent mining.
For an ordinary user
An ordinary user will break through the ads and check the video card every time, so we consider the option only from the store, and then ... GTX 1660 / Super / Ti.
Do not be fooled by suspiciously low prices - they are scammers!
Why is that? Well, firstly, at least some kind of thaw has begun with prices. They have not yet returned to their previous level, but at least they have stopped growing, which is already pleasing. Secondly, cards from the store and with a guarantee of three years, which means that if something happens to it, then you can take it to the store and repair it.
Someone says that stores don’t repair vidyuhi after mining, but for starters, let them first prove that the video card was in the farm, since mining is, in fact, a process of ordinary miscalculation, and a picture similar to it can be achieved ... Calculating something on the video card for quite a long time.
Also, Nvidia cards have a significant plus for the layman: the optimal settings can be set directly from under Windows, you can see them for each card separately. The yield on the 1660Super will be the same as that of the cards for experienced miners, but each 1660S will cost an average of 10 thousand more than one RX.
But at the same time we have a guarantee, the same income, but slightly less consumption (by 30 watts), the cards are newer, which means that later they can be sold at a higher price (relative to RXs).
