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! If you guys enjoyed this tutorial and found it helpful

enjoyed this tutorial and since you made it all the way to the end,
thanks for watching.
