a wild advertisement appeared if any of
you guys need a legit website for your
tech YouTube channel blog or whatever
the dot tech squad is offering $5.00 dot
tech domains until April 8th with the
code
awesomesauce this is a new initiative so
many domain names haven't been taken yet
that's why I was able to score
awesomesauce Tech before any of you guys
could snag it first and try selling it
to me later
trolls go check it out I put a link in
the description ok bye what's up guys
today I'm dealing with a topic that
might not require much explaining to you
DIY veterans out there but for the
novice or first-time PC builder choosing
the parts for a PC and ensuring they're
all compatible with each other can be a
daunting task so to make life a little
easier for the young PC master-race i've
decided to throw together the ultimate
PC hardware compatibility guide the
first step is to make a list of parts on
PC port picker comm and see if you pass
the site's compatibility check if it
checks out you're done guys thanks for
watching I hope you learned a lot from
this video wait hold on
let's back up I need to throw together
the ultimate PC hardware compatibility
guide now while a PC list making site
like PC part picker already offers a
built-in compatibility checker after
doing some research I found that such
automated systems aren't always 100%
accurate especially when it comes to
gauging specific clearance parameters or
taking specialized situations into
account so hopefully by the end of this
video you'll have a greater
understanding of how various PC parts
relate to each other and thus a higher
chance of choosing all the right
hardware that being said I use PC part
picker all the time personally it's a
fantastic site that I'd recommend using
too part out your belt I'm just giving
you the necessary information in this
video that a universal algorithm can
always provide so in order to thoroughly
explain the vast network of PC part
Association I've been working with a
team of highly intelligent field mice to
develop the octagon of compatibility
these are the 8 main parts you'll most
likely need to build your next PC for
the record I've omitted optical drives
here because one they're not nearly as
relevant these days and two there was no
more room in the Octagon looking at the
chart you can think of each of these
parts as a puzzle piece that needs to
fit with certain other parts in the
group to make a working computer here's
what all the compatibility lines for
every part looks like and we'll be going
over each of
today now I can tell most of you are
already like this I'm out of here
but don't saddle up just yet because I'm
gonna break it down for you all nice and
simple so that even a child or a Donald
Trump supporter can understand rather
than trying to tackle all these lines at
once let's start by talking about the
computer case and work our way around
the octagon so for starters the
relationship between cases and
motherboards is pretty simple
motherboards come in a number of sizes
or form factors but the most common ones
from smallest to largest are mini ITX
micro ATX ATX and extended ATX or EA TX
for short once you know what kind of
board you're dealing with you can look
on a cases product page to see what
types of boards it supports some cases
support more than one type of board but
I would advise against putting a small
board inside a larger case if you want
to use your system to its fullest
additionally your motherboard should
have the necessary headers for plugging
in your cases front panel connectors
this includes the elements at the front
of your case like USB ports to avoid a
lifetime of pain and sorrow take a look
at exactly what external connectors your
case is rockin then check for the
corresponding headers on your
motherboard as a quick pro tip a single
USB 3 header on your motherboard can
support up to two USB ports on your case
and the same goes for a USB 2 header
your GPU or video card also needs to fit
comfortably inside your chassis first
check to see how many PCI slots your
video card has then verify that your
case has the same number of expansion
slots or more these days most cards are
only two slots wide and most cases have
at least two expansion slots so this
really isn't a big concern if anything
you're more likely to run into clearance
issues with the length of your GPU again
check the manufacturers website this
time making sure that the length of your
video card is shorter than the cases
maximum supportive graphics card length
the height and thickness of the cards
cooler can also pose clearance issues
but usually that's only if you're
building inside of a toaster the CPU
cooler has a similar relationship with
your case as the GPU if you're going
with a non liquid air cooler the main
thing to look out for here is the height
of the cooler versus the cases maximum
supported CPU cooler height for all in
one liquid coolers pay attention to its
radiator size which is usually either
120 240 280 or 360 millimeters long then
check to see if the case in question
supports radiators of that particular
size to guarantee a cases compatibility
with a power supply there
factors to consider here the first one
being form-factor life motherboards
power supplies come in a variety of
sizes too but the two main types are ATX
and SFX SFX is typically only used in
small form-factor cases so unless you're
building a super portable PC chances are
you'll be dealing with an ATX power
supply this is kind of confusing since
as we just discussed ATX is also a
motherboard form factor but since they
signify different specifications it's
probably best to ignore the similarity
at any rate check both product pages to
make sure the form factor of your power
supply is supported by your case
secondly you'll want to ensure that the
length of the unit meets the
requirements for your cases power supply
clearance when building in smaller cases
I like to stay well under this limit if
I can just to give some extra room for
cable management thirdly you'll want to
look out for any fan controllers or LEDs
built into your case that require juice
from your power supply
these are usually driven by a SATA or
molex connector so make sure your power
supply has the right kind and number of
plugs the last part to consider for our
case here is storage whether they be
mechanical drives or SSDs most drives
that mount directly to your case are of
the two and a half inch or three and a
half inch variety count up how many
drives you plan to use in your build and
make sure your case has enough drive
mounts to accommodate them be aware that
many cases have Drive mounts that
support both two-and-a-half inch and
three and a half inch drives but not
concurrently unless otherwise specified
now let's move on to the motherboard
since this component functions as kind
of a central hub it's no surprise that
it requires compatibility with every
other part on our list of course we
already discussed its association with
cases so no need to revisit them when it
comes to the motherboard and CPU the
most important factor to allow
compatibility is the socket type common
Intel sockets of today include socket
LGA 1150 1151 and 2011 - v3 these socket
types need to match exactly for there to
be a working connection no exceptions
AMD on the other hand is a bit more
flexible in this regard and that it's FM
2 plus and am3+ motherboards are
backwards compatible with older FM 2 and
AM 3 CPUs just not the other way around
still it's generally recommended to use
an AMD cpu and motherboard of the same
socket type if you're set on buying a
case view Intel CPU for overclocking
you'll also need to check that your
motherboard
chipset supports it at the moment the
popular chipsets that support
overclocking include z97 C 170 and X 99
AMD users don't have to worry as much
here since overclocking is supported on
pretty much all the main chipsets apart
from processors your motherboard also
needs to support the correct standard
capacity and speed of your RAM or system
memory most boards nowadays support
either 240 pin ddr3 or 288 pin ddr4 so
you'll need to buy a ram kit sporting
the same type of memory if you're
choosing a kit with more than two dims
make sure the board has at least that
many DIMM slots to house them
motherboards also have a cap on how much
ram capacity they can support so if
you're opting for a 64 gig kit for
example make sure you're not buying a
board that only supports 32 gigs finally
you want to make sure your motherboard
supports the rated speed in megahertz of
your memory in order for it to operate
at its full potential in OC acronym
that's listed next to a specific speed
indicates that you'll need to manually
overclock your memory usually in the
BIOS in order to hit that specific
frequency moving on to motherboards and
graphics cards most boards you'll find
have PCI Express slots that can
accommodate any modern GPU but for good
measure you'll want to make sure both
parts are supporting the same generation
of PCIe the current gen as of filming
this video is PCIe gen3 if you happen to
be installing multiple GPUs make sure
you choose a board that supports the
same number of cards with either sli for
NVIDIA GPUs or crossfire for AMD now
compatibility between the CPU cooler in
the motherboard is very much like the
affair between the board and CPU as long
as your cooler supports the same Intel
or AMD socket as your motherboard you're
in the clear luckily most air and liquid
cooler support the vast majority of
popular sockets but still be sure to
double-check before pulling the trigger
like everything else in the PC the
motherboard gets powered by the power
supply but not every power supply has
the right connectors to power any board
the first of two main plugs to consider
here is your EPS CPU connector this will
either be a four pin or more commonly an
eight pin plug on your motherboard
either way I'd recommend a power supply
with an eight pin EPS plug which is
usually split into two four pin
connectors so we can work for either
scenario the second plug to watch out
for is the larger ATX motherboard
connector which usually has 20 or 24
pins
as such your power supply should have a
20+4 pin connector in order to power
your board now listen up carefully here
because compatibility between a
motherboard and your storage
configuration can be a bit tricky for
new builders to start with the basics
most SSDs and hard drives connect to the
motherboard via a SATA data cable in
order to transfer data most motherboards
have a number of SATA ports onboard for
exactly this purpose as for now the two
common speeds of this connection are
SATA 2 which features transfer speeds of
3 gigabits per second and SATA 3 with
faster speeds of 6 gigabits per second
while the average hard drive sees
virtually no performance difference from
either connection newer SSDs from the
last couple of years should always be
plugged into the faster port when
possible as an example if you picked out
four SSDs and two hard drives find a
motherboard with at least 6 SATA ports 4
of which should be SATA 6 gigabits per
second the new kid on the block when it
comes to storage is m dot 2 rather than
plugging into a SATA port and m dot 2
Drive mounts into an m dot 2 slot that's
built directly into some motherboards
the form factor of m dot 2 drives is
expressed with a key letter like m and a
four-digit number indicating its
dimensions so be sure to check the drive
specs and motherboard page to find out
which keys and lengths are supported but
wait there's more not all m dot two
drives use the same data transfer
protocol the two main ones being SATA
and the newer and faster and vme PCIe
now because the world hates you some
motherboards only support one or the
other and some boards support both when
in doubt check the manufacturers website
to see what's what if you're considering
an M about to drive for your build I'd
highly recommend watching Paul's video
on m2 before buying your parts now
believe it or not with the case and
motherboard behind us we've already
turned through the majority of
compatibility lines here that brings us
to the CPU which really only needs to
play nicely with three other components
one of which we've just discussed if you
remember how to pair a motherboard with
the CPU and you found a CPU cooler that
supports your motherboard by the
transitive property your CPU and CPU
cooler should also see no physical
incompatibilities since all three
components support the same socket type
however there's one more characteristic
that should be paid close attention to
and that's the CPUs thermal design power
or TDP which refers to the amount of
heat that needs to be dissipated for
effective operation track down the TDP
of your CPU then look to see if your CPU
cooler
is well cool enough to meet that
requirement if you plan on overclocking
your CPU I'd highly recommend a cooler
with a cooling capacity that exceeds the
on the box-t VP of your chip the TDP of
a CPU also gives us a general idea of
how much power it'll draw while your
power supply needs to be able to handle
the load of your CPU your video card is
usually the biggest power hog in a PC
and thus gives us a better estimate of
what wattage our power supply should be
in order to drive the whole system so
we'll circle back to this later when we
touch on the video card as we've already
gone over your memory and motherboard
have a defined set of specs that
determines their compatibility but the
relationship between your RAM and CPU
cooler isn't so cut-and-dry
this comes down to a matter of physical
clearance based on the height of your
dims and its potential to interfere with
your air or liquid cooler larger air
coolers with wide heat sinks or multiple
fans can often block access to your DIMM
slots leaving no room for installing
your memory modules a couple ways to
avoid this tragedy include finding an
air cooler with high ram compatibility
or choosing a low profile memory kit
which will greatly reduce your chance of
interference to be on the safe side you
should also research your model of CPU
cooler online to see if it's caused any
clearance issues for fellow builders all
in one liquid coolers can pose similar
clearance problems with their radiators
or radiator fans this is particularly a
concern if you plan on mounting your
radiator at the top of your case where
it could potentially hang down to low
and clash with your dims again a low
profile memory kit can do wonders here
but equally effective is choosing a case
that features either a top radiator
mount with ample spacing away from your
motherboard or radiator support on
different sides of the chassis next up
we have the video card and assuming you
were listening when we talked about case
and motherboard compatibility that
leaves us with how to select a proper
power supply for our GPU and our whole
system for that matter on the graphics
card manufacturers website it should
list in plain view the minimum
recommended power supply wattage
required to drive the entire system
safely for peace of mind
I typically opt for a unit that's about
a hundred Watts greater than this
recommendation and 150 watts greater if
I plan on overclocking my CPU and video
card if you want to find out exactly how
much power your system will draw add all
your parts to a list on PC part picker
and the site will spit out a fair
estimate of your PC's total power
consumption before overclocking now
getting back to the GPU
a minute sufficient wattage is only half
the battle as your power supply also
needs to have the appropriate PCI
Express connectors to power the card
unless you're dealing with the low
powered GPU with no PCI connectors most
cards will have a number of them in six
pin or eight pin varieties check to see
that your PSU has a sufficient number of
the correctly sized plugs or you'll be
stuck with an overpriced paperweight
keep in mind that many power supplies
feature six plus two pin PCIe connectors
which can be used for either a single
six pin or eight pin plug on your
graphics card at this point we've talked
about nearly every part associated with
the CPU cooler but there are some rare
instances where your cooler can
interfere with your power supply this is
usually only a concern in small
form-factor cases where the power supply
is mounted directly above the CPU in
order to save space in this situation
you'll need to find a liquid cooler if
your case supports it or a low profile
air cooler that's shorter than your
cases maximum CPU cooler height limit as
you guys can see there's really not much
left to say about our power supply
either other than its requirements for
storage earlier we talked about how SSDs
and hard drives require a SATA
connection to your motherboard for data
transfer but these drives still require
a second SATA connection to receive
power as such your power supply needs to
have at least one SATA plug for every
one of your hard drives and don't forget
to account for any other elements like
fan controllers or LEDs that require
SATA ports as well finally that leaves
us two storage but by now we've
exhausted all of its various part
associations thus concluding today's
lesson on the octagon of compatibility I
know this was a lot of thick information
to run through guys and there's a fair
chance that I overlooked a few things
myself so if you're watching this video
