hey everyone and welcome back to another mining chamber video in this video i'm
going to be talking about power supplies and tell you guys what you need to look for when
you're buying some for mining as well as give you my top five options for it i will also show
you the recommended ways that you should power your gpus and cover the different
adapters that you can use so now let's go ahead and get into it right after the intro
when you're looking for a power supply as a miner there are a couple of things that you want to pay
close attention to so before we talk about the top five options let's cover the basics first so
you can understand the reasoning behind the top five first knowing how much wattage you need for
that you need to keep in mind that gpu's mining use less power than gaming so you don't need
to be looking at the tdp instead check how much wattage your gpu uses for mining and a good place
to do that will be miningchamber.com you'll find different gpus there with how much wattage they
use mining a certain algorithm if you don't find it there then you can look into whattomine.com
or other resources as well now add up how much wattage it will be for all the gpus and then give
up to 200 watts for the other parts and if you're not using any fans then giving it 100 watts max
will be good so whatever total that comes out to in wattage you want to make sure that it does not
surpass 80 percent of whatever psu you're trying to use so if the total is 850 watts then getting
at 1200 watt psu will be more than enough although there is a safety concern in this because these
calculations are based on certain overclocks and undervolts that you need to make sure to apply to
your gpu and if those settings ever reset then you are in the danger zone because you will be
pulling a lot more than 850 watts so it is a good practice to get even more wattage but if you're
using a linux based mining operating system or tested and kept a close eye on your overclocks
then this is not much of a problem to you and then you have the ratings the ratings represent
the quality of the wiring that is used within the power supply the higher the rating goes the
safer and more efficient the power supply becomes generally getting gold and above is completely
fine and if you're looking to maximize efficiency you can go for platinum or diamond but the numbers
for efficiency is pretty small to notice unless you're running a big farm so i would recommend
getting the best deals price wise when it's gold and above one of the most important factors is the
amount of pcie cables that it comes with as a gpu miner you want to make sure that you have the most
amount of pcie cables that you can get also known as vga these will help you connect more gpus with
peace of mind these cables come in three different variations you have a single eight pin dual eight
pin and eight plus six pins the more pins the better so having dual 8 pins is always preferred
there are multiple ways that you can utilize your pcie cables in your gpu mining rig but almost
always you will need splitters splitters basically take in a single eight pin or a six pin and gives
you in return to eight pins making it easier to effectively power more gpus and risers here are
some quick different methods that you can use to power your gpus and risers method 1 is for single
8 pin cards you can use a single 8 pin cable and connect it to either a 6 pin or an 8 pin splitter
and then from there power the gpu and the riser with the 2 8 pins and then method 2 is for dual
8 pin cards this will be using a dual 8 pin cable with either a 6 or an 8 pin splitter 2 dual 8 pin
and it will work with any gpu except rtx 3090s you want to connect the splitter to one of your 8
pins and then you will have a total of 3 8 pins 2 will be for the gpu and one will be for the riser
and for method 3 it's also 4 dual 8 pin cards when you're running short on cables this will work only
on gpus that uses 150 watts or less for mining out of the wall you will be using two cables of
dual 8 pins and 2 splitters to power 3 gpus you will have a total of 6 8 pins using the splitters
and then from there you can do one and a half gpu per pcie cable spreading the load of three
gpus on two different cables as for the risers you will have to use molex cables two risers per
molex or you can also add two more splitters to power two risers and then one riser with molex
and then finally for the high power cards that use 250 watts and above while mining you will need to
use two full cables to avoid overloading your psu cables so far only the rtx 3090 fits this category
but whenever new cards come in or you have to mine ravencoin with your 3080s then you might be using
more power than just 220 watts don't power two gpus with one cable unless it's a gpu that uses
less than 80 watts off of the wall while mining like a 1660 ti so now that we covered most of the
basics that you need to know when it comes to psus this topic is very broad and there's a lot more
information on them such as wattage limitation and where all the other cables go so if you want to
learn more on that then you can check out my two guides on psus one is for atx and the other one is
for server power supplies which i will leave in the descriptions below so that being said let's
have a quick word from this video sponsor and then move on to the top 5 psus for gpu mining
privacy and online security is a crucial part in the cryptocurrency world if you are a trader minor
or an investor you always want to be vigilant when it comes to your security and privacy
and one of the ways to boost your privacy is by using a vpn which brings us to today's sponsor
and that's nordvpn nordvpn is one of the most popular choices and they also have a no log policy
which means they'll only be collecting what they need to run their services and nothing else
so your data will be your own and nordvpn also has an app for your android or iphone and you can also
use it on mac or windows so start using them today to avoid geographical censorship and to keep your
online traffic encrypted which can be especially useful if you find yourself using a public network
pretty often they currently have a special deal for a two-year plan for only three dollars and
seventy-one cents which means for a full two years you're only going to be paying for eighty nine
dollars and then with every purchase of a two-year plan you will get one additional month for free
using my code mining chamber so please feel free to use it and take one further step into your
online privacy with nordvpn for the top 5 psus i will be ranking them from 5 to 1 and then 1 being
the best one so the first one we have on number 5 is the alibaba psus now those alibaba power
supplies come in different styles so you have ones that are thousand six hundred watts up to two
thousand watts and they have a lot of pcie cables they can go anywhere from four six plus two pins
to twelve six plus two pins which is really really good now these power supplies also have different
voltages most of them are running from 180 to 240 volts so you want to make sure that you're careful
on that and generally they are a good choice if you're planning on building a lot of mining rigs
because they come for cheap but some of the cons is that the sellers might sell you a minimum of
five pieces and there's also the chances of getting bad power supplies and then having
to deal with that after so the reliability part for the alibaba power supplies is not that good
but other than that they're fairly cheap prices if you're trying to build a lot of mining rigs
and then on number four we have the rmx 850 watts power supply now this is a gold rated power supply
and it's modular this is one of the most common power supplies that i personally use for mining
and i have a couple of rigs that i've used more than one of these power supplies on them and
they've worked completely fine now the pcie cables that come with this power supply usually have two
cpu8 pins which you can use one of them for a gpu once you get a cpu to gpu splitter and they
also have three pcie cables with dual eight pins which will end up giving you six to eight pins
now that with the cpu cable that means you can easily run four gpus on these power supplies if
those gpus don't consume more than eighty percent of its capacity this power supply comes for the
price of 145 dollars plus tax let's say around 150 dollars but also one thing to keep in mind is that
you don't really need to always go for the corsair brand if you want to go for any other 850 watt
power supply it's also completely fine now one of the best pros about these power supplies is you
can grab more than one if you need to expand your gpus later so first you can start with one power
supply if you have like three gpus and then once you get three more gpus you can also buy another
one and then use a power supply splitter and use two power supplies in your same rig now the cons
of that is having two power supplies that means you need to use two wall outlets to be able to
power both of these power supplies and if you're looking for any adapters such as the cpu to gpu
splitter or the power supply splitters then you will be able to find them in the descriptions
below and then for top three we have the evga supernova 1200 watts platinum power supply
now this is also another power supply that a lot of miners use and it comes for a price of around
330 dollars now on amazon you will be finding it for more expensive and like i said you can
use another 1200 watt power supply but generally the evga p2 comes with a good amount of cables
now this power supply comes in with two cpu8 pins and it comes with six pcie cables four of
those cables are just eight pin to eight pin so it's just a single eight pin and then the
two other cables are a six and an eight pin so you have a total of six eight pins and two six
pins with those six pins you can just use six spin splitters and then you'll have dual 8 pins
and then from there you can use these cables to power a lot of gpus this is usually a great power
supply if you're trying to build a 6 gpu mining rig with a combination of single 8 pin cards
and dual 8 pin cards and it also runs at 120 to 240 volts so you can run this basically anywhere
and then in top two we have the server power supplies so the server power supplies can be a
little bit intimidating at first so with whatever i'm saying does not make sense to you then i
highly suggest watching my server power supply guide first and then everything will be crystal
clear for you so the reason i have server power supplies as number two is because they're super
efficient and they're also super cheap the best thing about them is that they come with these
breakout boards that you can put a lot of six to eight pins on them and then you'll never have to
struggle with having less power cables for the risers and the gpus so it makes your life a lot
easier from that side of things but the negative side of it is that they're super loud and they
also get really hot so if you're running your mining rig in your bedroom or in your living
room then this might not be your option but i'm putting it as number two because this is very good
option for people that have dedicated mining rooms or they have their mining rig somewhere
that's not too close to them and then they can just have these server power supplies going at
it so for the server power supplies i usually buy them from parallel miner and if you guys want to
look for them in ebay it's completely fine but i'll just use parallel miner as a guide because
they have everything there super clear and they have really good options there as well so there's
two parts of it that i'm going to recommend to you first is the power supply itself and then it's the
breakout boards so for the power supplies there's a 1200 watt power supply it's an 80 plus platinum
and it's super efficient so this one can run on 120 volts or 240 volts but on 120 volt you
can only pull 900 watts out of it so please keep that in mind now other than the 1200 watt
hp power supply you also have the delta 2 and 400 watts power supply now this one is a monster and
it's great for big projects such as 12 car rigs and it takes in two different breakout boards it
also only runs on 200 to 240 volts so also keep that in mind now as for breakout boards there's
three options that i recommend first you have the zsx breakout board with 16 ports as well as a pico
adapter built into it so this one can run your mining rig with your motherboard and everything
just through the breakout board and it has 16 ports that means you can do 16 8 pins on it so
with splitters that means you'll have 32 8 pins which is amazing and then another option will be
the x11 16 port so this one is the same as the other one except that it doesn't have the pico
so if you're trying to run a full mining rig with it you won't be able to because you don't
have a cpu or 24 pin cable from this breakout board but it does have 16 ports so that means
it's another 30 to 8 pins with splitters and then finally the last one will be the x1512 port now
this one is a mini one and it's for small scale builds or you can just have it additional in your
2400 watt power supply if you don't want that many ports so that is it for the server power supplies
like i mentioned if you want more information on them such as how to use two of them together and
all that stuff then please check out the video that will be linked in the descriptions below
and now finally for the top one option it is the v platinum series from cooler master
now these power supplies have different wattage they can go anywhere from 1 300 watts to 850 watts
and yes this is more than four power supplies in the top one option that is because this is great
for mixing and matching so you can go ahead and select for example the 850 watt and then
also with another power supply based on how much power you need so it gives you the peace of mind
of mixing cables and using them all together now the minimum amount of cables that you'll get from
these power supplies based on the wattage that you get is three dual eight pins and one single eight
pin up to six dual eight pins and a single eight pin so you have a good amount of cables that come
from these and they're also platinum which is more efficient and their price point is not bad either
but the only issue is is that these are hard to find online so if you do find them then
that's great you can buy them but if you don't find them then you'll have to check out their
different stores and see where you can buy it from on amazon you can see the 1000 watt option for 309
which is a fairly good price for a platinum power supply and then for the rest you can just look
around until you find them i will try to add their links in the descriptions below whenever
i see them available now that gives you the top 5 power supply options that i recommend you to use
for gpu mining now all these options will also be on an article in miningchamber.com so you'll find
the full write-up on this video with some more details on there as well so feel free to go ahead
and visit miningchamber bookmark the website and then you'll always have it there whenever you need
it now i know i gave you guys like top 10 power supplies rather than top five but this is just to
give you options so you can use different ones if you can't find the ones that i'm mentioning
like that you'll never have to think too much on getting a power supply also make sure that
you use the information that i mentioned in the beginning wisely because that is very important
i know right now buying a gpu mining rig is kind of scary because of ethereum 2.0
so if you haven't watched the video on ethereum 2.0 feel free to check it out the link will be
in the descriptions below and if you do decide to buy a mining rig this guide is there to help you
now i'm not saying you should buy a mining rig or you shouldn't but if you want to mine and
you're determined to mine now you have a couple of power supply options that you can go off with now
that wraps up the video if you guys enjoyed this video please leave a thumbs up and if you have
any questions let me know in the comments below and if you're new here make sure to subscribe i
have two more videos that will be coming out one will be the top five gpus for mining and
then the other one will be top 5 motherboards for mining and whenever they're out i'll make
sure to put them in the descriptions below thank you guys again and i hope you have a wonderful day
so you
