Hey guys, this is Austin and today I’m here with part three
of my computer build tutorial.
The last two videos have gone
over how to install everything in the case but now it’s time
to hook it all up and finish the computer.
Time for the really
fun part, wiring.
I’m actually lying, wiring is no fun at all
however as long as you think a bit about how everything connects
it’s really not all that bad.
First step is to grab the pair of
SATA cables that came with the motherboard.
Plug both of these
into the connectors on the bottom right of the board.
Grab one
and run it up to your hard drive.
As you can see they’re notched
so they can only go in one way.
Simply press it in until it
clicks.
Now do the same with the other cable for the DVD drive.
Now you should see some cables attached to the case.
Grab the one
labeled HDA which is your front panel audio.
There is a single pin
knocked out so you can only plug it in one way.
On this motherboard
it’s in an awkward spot between the graphics card and the audio
connectors however with a bit of work it will fit.
You’ll also see
your front panel USB.
This works the same way except that thankfully
this is much easier to install.
Just plug it into the USB connector
on the bottom of the board and you’re good.
You’ll also see a small
bundle of umbilical cables for the power button and LEDs.
These need
to be plugged into the front panel connectors beside the SATA ports.
If you look closely you’ll be able to see that where each cable goes
is marked on this tiny pin out however if you look at your motherboard
manual you’ll see it recreated a bit better.
The most important thing
is to note the positive and negative sides as obviously plugging them
in wrong won’t work.
I won’t go over each and every cable but once you
get going it isn’t that hard.
Once you’re done it should look a little
something like this, not the neatest thing in the world but it works.
Move over to the heatsink and unwind the power cable.
This is a 4-pin
connector with a pair of notches to make sure you plug it in correctly.
Find the CPU fan connector on your motherboard and plug it in.
Covering
up the camera with your arm is totally optional of course.
Let’s
continue connecting fans.
The Antec 300 has a pair of fans and both of
them have the same type of connector except as a 3-pin.
You’ll find
another system fan header on the bottom left of this motherboard to
hook up the exhaust.
Unfortunately this motherboard doesn’t have
another connector so we’re going to have to come back for the third
fan.
Now come down to the power supply, unwrap the cables and pull them
out of the case.
Before we get into connecting everything let’s go over
what cables do what.
The biggest connector is your 20-pin motherboard
power cable.
This is what powers everything on the motherboard and it
also uses an additional 4-pin connector.
You’ll also find a 6-pin cable.
This is generally for powering graphics cards and depending on the power
supply will sometimes have an additional two pins for higher power cards.
Moving on you’ll see these larger connectors which are known as molex.
We really won’t be using these in our build however they can be useful
for using with adapters which we will be doing.
You’ll also see a pair of
4-pin connectors.
These are for CPU power and also connect to the
motherboard.
Lastly we have these long flat cables which are SATA power.
This is what we’ll be using to power our hard drive and optical drive.
I know this is a lot to go over but it’s really pretty simple.
The first
thing to plug in is the 20+4 pin motherboard power connector.
It’s best
to route this behind the motherboard tray but the cable is a bit short
on this power supply so just push it all the way back.
Once the main
cable is connected plug in the additional 4-pin connector.
Now you’ll
need to power the graphics card.
The Radeon 7770 only needs a single
6-pin connector so press it in until it clicks.
For the hard drive and
DVD drive you’ll need to grab a pair of SATA power cables and plug in
the hard drive on bottom and then the DVD up top.
Again, depending on
the power supply and case it’s usually best to run these behind the
tray and then back out to make everything is as neat as possible but here
we just need to stretch everything to fit.
Since the power supply is
unraveled we can now connect the last fan.
I had a 3-pin to molex adapter
lying around which will work perfect.
Just connect the male and female
molex ends together and then connect the fan to the 3-pin connector and
you’re good to go.
Last but not least we’ve got to connect the CPU power
which are the pair of 4-pin connectors.
This motherboard only uses one so
locate it up at the top left of the board and click it into place.
Amazingly enough we’re almost there.
All our parts are installed and
everything is wired up.
It looks like a minor computer explosion now but
we’ll clean up our wiring in a minute.
Grab the large AC power connector
and plug the power supply into the wall.
Then grab a monitor and keyboard
and connect everything together.
Now’s the scariest part of the entire
build, seeing if it actually works.
Hit the power button and give it a go!
If it boots give yourself a high five, you did it!
If not don’t worry too
much, usually it doesn’t work first try.
Go back and double check all of
your connections and make sure the power supply is switched on.
Once it
does turn on and get into the BIOS take a look at the build.
Are all the
fans running?
How about on the graphics card?
Check the power supply as
well.
If all’s good there go into the BIOS and take a look around.
It
should detect your CPU and installed memory and your hard drive and DVD
drive should show up as well.
If everything looks good you’re almost
there.
We’re not quite done yet though, the inside is still a bit of a
mess.
Cable management is an important part of the build to make future
upgrades easier, improving air flow as well as just making the build
look better.
I won’t show every step along the way but the basic idea
is to group cables as neatly as possible and use electrical ties to hold
them together.
I didn’t do a great job here but considering how short the
power supply cables are it’s good enough and a major improvement.
Now put
the side panels back on, screw them in with your thumbscrews and you’re
all done!
Congratulations, you’ve built a gaming computer!
