How to Build a Computer for Gaming (2012) Part Three


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
I’d really appreciate it if you could leave a thumbs up! If you want to

  1. I never realized how easy it was to build a pc. I can't wait to get started. Great video! Although the voice thing at the end of every sentence was kind of annoying. No worries though 🙂

  2. The front panel connectors that are on this case I have the same and I can't find were to put them all on my motherboard

  3. Thanks Austin ….this video help me much more than the other the picture quality is hd and a great description…….if possible then 1M likes

  4. Check connections, if everything looks right then check monitor and power to it.

    Maybe the monitor isn't hooked up correctly? Are you sure it works? If so, it has to do with your PC. Look for fans on the pc and see which ones are working, if one isn't working check the connection between the power supply and that component with the fan.

  5. Check that the cables connecting the monitor are connected properly and if the power to the monitor is ok and finally check to see if you actualy turned on the monitor.

  6. Hats off to you. Dude, I never realized how easy it was to do this. I am most likely going to buy the same parts you used and try to replicate the process. But thanks so much, I am so excited because maybe, MAYBE next year I can do this. But for right now my normal PC is fine and can play games with decent graphics.

  7. You have to put the disc in the BIOS is already there, but it only shows the parts you have to insert an OS disc 🙂

  8. Uh no I don't know what my friend's Computer specs are but he runs Minecraft at 35+ Fps. But I'll ask him what they are and as soon as he tells me I'll tell you

  9. No idea, but I know I use a Radeon Saphire HD5450 with 2.6 ghz. I also have 2 GB of RAM :/. It cant play stuff like BF3 on probably even medium graphics and I couldn't even get on the BF4 beta because of issues involving graphics, but I recently played bioshock and didn't fool with the graphic options and had no lag.

  10. i have a PSU with only one 6pin connectors, and my VGA is HD 7870 XT uses two 6pin, and i don't know how to connect the molex that comes with the graphic card to the psu

  11. Hey austin, what do i do if i run out of seta power cables? For example in this build if i wanted to add another hard-drive? A quick response from anyone would help. Thanks ~Dean

  12. SOMEONE PLEASE READ AND HELP ME!!!

    I want a gaming pc that I can use for youtube editing and gaming. I just want a pc with really good graphics and superfast (meaning you can open the internet in less than a second). And runs games smoothly. How much will that cost me? I am making the switch from console to pc. Please help.

  13. i have triple checked everything and it still doesn't work, i didn't use the same parts but i assume its not that different, PLEASE HELP ME!!!!!!!!!!! i don't know wat i did wrong

  14. Finally I finished I have my computer built and finished except for a operating system I'm going with windows 8 pro and I have the 400$ build but I upgraded to 8gb ram 1t hard drive

  15. Having a lot of trouble with the 24-pin. Ive look it up on the interwebz and saw this is a common problem. Although it still won't go in. Anyone here who has some advice?

  16. I have a dell xps 730x and the side of the case that does not open fell off. Does anyone know how to reattach it? ie use some kind of glue or something?

  17. This is the best guide on internet thanks a lot my friend, but can i ask you something i'm building my own computer for gaming and i need your opinion.
    CPU : Core i5-4440 3,3GHz 6MB/1150 
    GPU : SappHire HD 7850 1GB
    Memory : Apacer 8GB DDR3
    Is this good for gaming ? can i play the newest games 2014-15 Low/Medium ?.

  18. hey austin im trying to follow this build except im using an intel celeron instead of the i3 its a cheap build now but any idea how i can install windows on it i cant seem to boot it from the usb it just freezes and restarts

  19. could someone help me i built a gaming pc yesterday and this morning i tried to turn it on and everything seemed to work i didnt have it plugged into a monitor so i could not see what was happening but about 30 secounds of the pc working it turned itself off i cant understand it i have tried it about 30 more times and the same thing keeps happening could someone please help me with this ???:(

  20. SO yea what should I do if I turn on my power supply and a puff of smoke comes out?… I'm making a new pc build and I don't want to mess the other parts up… 

  21. My tower doesn't turn on when i hit the power button… I suspect that it might be the motherboard 🙁 I don't know what i should do… What else to check for?

  22. Ok this is probably a very noobish question but in the video he doesn't put a cord or anything to the power button so how does it work

  23. I have a quick question can someone help me out? I have a gigabyte H81M-S1 MOBO and I have a zotax gtx 970 in it I'm still learining allt he slot and stuff on the mobo would there be a place for me to put a second GPU? the only other slot I see is a PCIEX 1_2 what is this for? would appreciate any answers thank you

  24. i have Gigabyte GA-H61M-S Intel 3rd Motherboard / Intel H61 Chipset
