Last Updated: 15th April 2015 - (Rewording of Introduction) This is a step by step, illustrated guide on how to put together your parts, complete with detailed photography and commentary; it can be supplemented with a video tutorial such as Newegg’s ‘How to Build a Computer’ series found The process of assembling your own PC is actually very simple in contrast to most people’s expectations. Compared to researching part selection, actual assembly is a much simpler task. Many prospective builders are often overwhelmed at the idea of assembling their own PC from scratch. However, over the years, the desktop PC industry has become quite standardized. It’s almost impossible these days to install the individual pieces, cables and connectors in the wrong location. Many builders will often relate the process of assembling a PC to building Lego which can only fit together in a single way.

The guide below can be followed step by step, however not everything must be done in an exact order and the order of some of the steps depends on personal preference. If you are ever in doubt about your components, remember that manuals contain a wealth of information. Indeed, for small form factor builds it is important to follow the assembly instructions found in the case manual, as smaller form factors often require a particular assembly order. Some people prefer to test boot their PC outside of the case (using a box or non conductive surface as a base for the motherboard). However, given that DOA (dead on arrival) parts are a very rare occurrence, this is usually unnecessary. For this reason this guide does not include an external test boot, but indicates when you can do this if you wish to.

What you will need Essentials. Wire Cutters Simply to cut the excess off the cable ties neatly. Can easily be replaced by a pair of scissors or a particularly sharp set of teeth (though we are not liable for any dentist bills which may occur!) Build Precautions Static electricity is a topic which is often discussed by first time builders as, after all, an invisible threat which has the potential to do damage to delicate and expensive components is a scary thought. A very commonly asked question is what precautions can be taken and which are necessary.

In truth, the vast majority of experienced PC builders do not use grounded wrist straps and similar solutions and simply take basic precautions such as touching a grounded object (for instance the metal case of a plugged in appliance). However it is of note that ESD (Electrostatic Discharge) damage does not have to prevent booting or functionality totally and can cause minor damage which may only be evident as BSODs in very specific circumstances. A method some builders use is to plug in to the wall (but not switch on) your new PSU and touch that periodically in order to discharge any static. It is also recommended that don’t build on carpet and avoid wearing socks or loose fitting clothing. Parts being broken on arrival or breaking in use is a very rare occurrence, however it definitely can happen. For this reason you will want to keep all packaging and boxes for your parts for the length of their warranties (which can be a very long time depending on the component) The Parts. A MAJOR CAVEAT - As you may recognise at a glance, this is not a good or balanced build!

The photography was done with these parts purely because that is what we had to hand at the time. If you are looking for a gaming build at around this budget you can see our recommendations in the / Type Item Price CPU $62.99 @ Amazon Motherboard $81.98 @ Newegg Memory $139.99 @ Adorama Storage $159.98 @ OutletPC Video Card - Case $55.89 @ Newegg Power Supply $59.99 @ Newegg Total (before mail-in rebates) $610.82 Mail-in rebates -$50.00 Total $560.82 So without further ado, let's begin!

Before beginning, I should probably state that ChooseMyPC takes no liability from damage caused by following this guide. Now that's out of the way. First we will be assembling the main components of the PC outside of the case for convenience Installing the CPU Take the motherboard out of its protective bag and place it on top of its box (a perfect non-conductive workspace which is the right size to fit the motherboard on). Do not place the motherboard on the anti-static bag it was in - although most commonly used designs for bags are not conductive this is not a good work surface and you are better off just using the box as the bag only offers protection when parts are inside of it. Lift the CPU retention bracket lever from underneath its latch by pushing down and out away from the cpu socket.

Bear in mind that depending on the socket of your motherboard, this may vary slightly and referring to the manual that came with the motherboard is advisable. Unbox your CPU at this stage and remove it from the protective moulded plastic, holding it carefully by the edges Now proceeds the most nerve racking part of the build. Lift the CPU retention bracket lever to reveal the socket and its pins. These are incredibly delicate and easy to bend (which motherboard manufacturers will not accept an RMA for), so be very careful when working around the socket. All CPUs have an arrow in one corner corresponding to an arrow printed on or around a corner of the motherboard socket to indicate which way round it fits.

The text on the CPU is also an indication of the 'right way up'. In addition to this, Intel CPUs also have notched sides on the upper left and right edges which match up with the shape of the socket.

Assembly Guide

Gently lower the CPU into the socket in the correct position. You should do this so that the CPU stays as horizontal as you can and makes contact with all pins as close to the same time as possible, however there is obviously some room for error. No force needs to be applied at this stage as this is the job of the retention bracket - the CPU should just fit neatly in its place. If your protective plastic socket cover is located on the inside of the retention bracket, you may need to remove the protective plastic cover which was over the socket at this stage.

Assembly Guide For Rb7 Extension

With our motherboard the protective cover is on the outside of the bracket so will pop off when securing the CPU into the socket. Gently lower the bracket over the CPU, sliding it onto the raised pillar on the motherboard. Push down the retention bracket arm and hook it back under the latch where it was originally. This may take some force, and may even cause some rather worrying noises, however if you have placed the CPU in the correct position in the socket no harm will be done and this process ensures that the CPU is in proper contact with the socket.

This is an area where more detailed video guides can be watched for reassurance that you are doing the right thing and applying a normal amount of force if you are particularly worried about this step The protective cover will pop off as you lower the lever. Be sure to keep this in a safe place, as you will need this if you have to send your motherboard back to the manufacturer to protect the socket during shipping. Your CPU is now installed into the motherboard. CPU Cooler Installation If you are using an Intel stock cooler (one which is bundled in the box with the CPU) remove it from the packaging and place the pins in the corners through the holes surrounding the CPU socket (ensuring that the pins at the corners are rotated to an unlocked position by rotating the top of them in the direction of the arrows). After this, turn the top of the pins in the opposite direction to that shown by the arrows to lock it in place. You can check that it is seated correctly by attempting to gently twist it - there should not be any significant movement. Be sure to arrange the fan cable so it doesn’t interfere with the spinning of the fan.

If you are using an aftermarket cooler there are a vast array of different mounting mechanisms and so you will need to follow the instructions provided with it ensuring that you use the correct mounting hardware and applying thermal paste as a BB sized ball in the centre of the CPU if necessary. Some CPU coolers, similarly to stock CPU coolers, have thermal paste pre-printed to the underside for easy application (this is frequently the case for closed loop coolers) Plug the 4pin PWM fan connector on the end of the wire coming from your CPU fan into the CPUFAN header on your motherboard at this stage if you wish (we actually forgot about this until the build was already in the case). Watch that the cable isn’t in the way of the fan blade! RAM Installation As the final part of this sub-assembly we will be installing the RAM into the motherboard. Read the motherboard manual to find out which slots you should be using for the number of sticks of RAM you have (they are usually color coded and so can be easily referenced). We will be populating all the slots in our build.

First, pull back the clips on either side of the RAM slots you are going to use Notice the clear off-centre notch at a point both on the slot and the RAM stick to indicate which way round the sticks should be placed and ensure they can only be placed one way. At this point in the build, if you have integrated graphics you can attempt to power on the build outside of the case by connecting the power supply 20/20/24 pin ATX and 4/8pin EPS connectors and shorting out the PWSWITCH pins on the front panel headers by touching a conductive screwdriver or paperclip to them for a split second or connecting the actual case switch to power the build on. Installing the Motherboard in the Case We can now move this sub-assembly into the case Best part about having a side panel window is peeling this off Take off the case side panels. You may need your screwdriver to loosen the thumb screws securing the side panels first of all - they are often very tight from the factory Find the box containing your screws and other accessories which are bundled with the case (it is usually located in a 3.5' drive bay) and find the standoffs for your case. These sit between your motherboard and the screw in order to stop the motherboard touching and shorting out on the case and are vitally important. In our case, the standoffs were pre-installed for an ATX motherboard. It is a relatively painless process, if they are not, to go through screwing the standoffs into the case in the locations where your motherboard has a matching hole for a screw.

DO NOT FORGET THE STANDOFFS. To repeat, our case had standoffs pre-installed for an ATX motherboard and so this step was not required. Otherwise you will need to screw the standoffs into the motherboard tray and the screws into that to offset the motherboard from the case and prevent it from shorting out. Next we need to install the motherboard I/O shield. This is a metal panel which covers the gaps between your motherboard I/O connectors in the cutout at the back of the case. Ensure this is the correct way round (engraved labels facing to the outside of the case and the right way up to match the connectors on the motherboard). This is a time when a lot of builders make their blood sacrifice to their machine on sharp edges, so take care!

Place the metal panel into the gap at the back of the case and push firmly around the corners and outside edges until it clicks to secure it. Now with standoffs in position and I/O panel placed we can take our motherboard and place it in the case. It is best to lie the case on its side as you do this. Lower the motherboard into place. Line up the connectors with the gaps in the I/O panel and push the connectors into the panel before lowering it all the way onto the standoffs. You may need to apply some pressure in the direction of the back of the case to line up the screw holes with the standoffs - this is normal and is the I/O panel resisting the connectors. However be sure that none of the metal tabs from the panel are making contact with the inside of the connectors after the process.

Find the motherboard screws which were supplied with your case (these usually have a built in washer) and screw them into the standoff, thus securing the motherboard to the case. Getting a Start on Cabling Here's the connection of the 4pin connector to the CPU header we left till now!

While you're connecting fans, you can connect any 3 pin fan headers from case fans to 3 or 4 pin fan headers on the motherboard. See the motherboard manual if you can't find their location. Start as you mean to go on with cable management!

With a first build it can be tempting to not bother to manage cables and that you will 'sort it out another time' but that way it takes more work later or never gets done - it's very satisfying to have a neat build afterwards, and you can be much more proud of any pictures you show off. It also ensures that cables do not get in the way, gather dust or obstruct airflow. Here we secure the excess cabling of our rear fan with a cable tie. Adding a Graphics Card Next we can move on to the installation of the graphics card. Remove the PCIe blanking plates corresponding to the slot you will be placing your graphics card in. Again, your motherboard manual will assist you in making a decision about which slot to use, but usually you should use the topmost PCIe x16 slot for your graphics card which more often than not lines up with the second PCIe slot blanking plate (and you will need to take off another below when you are using a usual dual slot graphics card) Press back the clip at the edge of the slot similarly to the RAM slots ready for you to insert the graphics card Lower the card into position and push down evenly at both ends until the clip engages. Screw the graphics card in to secure it in place - the graphics card will have holes in it similarly to those on the blanking plates allowing you to replace the screws which were originally there.

We now have all the major components of the build installed More Cabling - Case Cables Now things get more fiddly as we begin cabling. We are using a fully modular power supply which means that all the cables can be removed at the PSU end. If you have a non-modular or semi modular PSU you will have some or all cables which are permanently attached at the PSU end however this is not impactful apart from for cable management.

If your PSU is modular in some respect you can see where cables connect at the PSU end using the manual or matching labels on the cables/PSU) Place the 20/24pin ATX power cable and the 4 or 8pin EPS power cable (which is commonly labelled 'CPU Power') back through the cutouts closest to their headers. The EPS power connector will be at the top of your motherboard and 20/24pin cable along the edge. In most cases there is a cutout in the upper left corner of the motherboard to route the 4 or 8pin EPS power cable through in order to reduce cable clutter which you should use, however in our case this was not possible.

DO NOT plug PCIe connectors into your EPS power connector. This may seem very obvious (8 pin PCIe is differently keyed to 8pin CPU power) but I have seen people connecting a 6 pin PCIe power connector to their 4 pin PCIe power (with 2 pins hanging over the edge). If the number of pins does not match or the connector is impossible to insert for any cable due to keying, it is a safe bet that YOU ARE DOING IT WRONG.

Connect the 4 or 8pin EPS power connector to the CPU power connector on the motherboard. This is notched so will only fit one way. Pull any excess cable behind the motherboard tray. Connect the large 20/24pin cable to its header on the motherboard.

You can see which way this connects due to the clip and latch and it is once again notched to ensure it can only be connected one way. Once again keep the excess behind the motherboard tray. Route any required PCIe connectors for your graphics card through the motherboard backplate cutout closest to the graphics card.

All PCIe power connectors on the graphics card must be filled by a cable in order to successfully power the card. 8 pin PCIe power connectors from the PSU are often designed to split into 6 pin and a 2 pin optional part - feel free to use just the 6 pin part if you have a graphics card with a 6 pin connector you need to fill.

Insert these cables into the graphics card PCIe connectors which will be located at the side or end of the card. After this the build is complete and should POST to an error telling you that you have no boot drives connected, if you wish to test it at this point! Don't forget the power switch on the power supply itself and to double check all the above connections if your build shows no signs of life at all. Drive Installation Next you can secure any drives you have to the caddies inside your case.

We will simply be installing a single SSD and our case has tool-less drive mounting so we simply slot it into position. Other cases may require inserting drives into caddies using screws or other mechanisms and details of this will be listed in your case manual.

SSDs, having no moving parts, can theoretically be placed anywhere in the build including screwed to the back of the motherboard tray to reduce clutter. HDDs will require a proper mounting solution to minimise vibrations. Drives, including optical drives in the 5.25' bay, require two connectors - SATA data and SATA power. Both connectors are 'L' shaped so you can take a look before connecting it to see the correct orientation. SATA power can require a moderate amount of pressure to plug into stiff connectors. First connect one end of the SATA data cable which will be supplied with your motherboard and/or drive to the drive, and the other to a SATA port on the motherboard. It will usually connect with a satisfying click as the clip engages.

You should try to connect to SATA 6gbps (SATA 3) connections on the motherboard when using SSDs to ensure maximum speeds however this will not affect the speed of hard drives and will not impact the real world performance of an SSD significantly if you connect them to SATA 3gbps (SATA 2) interface. Next, take a SATA power cable from your PSU and connect it to the SATA power connector on the drive (next to SATA data). Finishing Up Now you are completely finished with building. Only problem is a lot of excess cabling at the rear side of the motherboard tray. Use cable tie points on the case to secure cables out of sight and route them in a channel along the edge of the tray. After this you can place the front and back panels back on the PC and you are ready to go! Enjoy your brand new PC and we hope your experience was a positive one.
