The Central Processing Unit ( CPU ), besides known as the processor, is basically the brain of your personal computer. This is where the charming happens — when a computer platform runs, it sends a list of instructions ( which are actually more like tasks ) to the CPU. The CPU performs each “ teaching ” and sends signals to other components to let them know when they need to perform a undertaking .
There are two main performance metrics that can help you choose the right CPU for your needs : core count and clock rush .
Core count tells us how many processors the CPU has — in other words, how many tasks the CPU can perform simultaneously.
Clock speed tells us how cursorily the CPU is performing each job .
Some higher-end CPUs sport hyper-threading, which allows each kernel to run multiple threads and offers better performance on threaded software .
Pro-tip : Most modern CPUs are multi-core and many modern games are designed to take advantage of this, so you should look for a CPU with at least four cores. extra cores can be helpful as you start layering on more tasks, such as record and streaming your gameplay .
The motherboard is the main circumference board and is connected to everything. The CPU sits directly on the motherboard ( your CPU and motherboard must be compatible — Intel® Desktop Compatibility Tool can help ) and every early component — graphics cards, hard drives, memory, ocular drives, wireless cards — integrates into the motherboard .
One way to narrow down your selection of a motherboard is to shop by size. The most common form factors are Extended ATX, ATX, microATX, and Mini-ITX .
- Extended ATX motherboards are the largest (12 by 13 inches or 12 by 10.1 inches) and can often have eight RAM slots (for up to 128GB of RAM).
- ATX motherboards are only slightly smaller (12 by 9.6 inches) and usually top out at four RAM slots.
- MicroATX motherboards (9.6 by 9.6 inches) can also have up to four RAM slots.
- Mini-ITX motherboards sport the smallest form factor of the four (6.7 by 6.7 inches) and often have two RAM slots.
Pro-tip : Every part needs to plug into the motherboard, so pick a motherboard that ‘s large enough to fit current and future hardware .
Random Access Memory ( RAM ) is your personal computer ‘s short-run memory. It ‘s faster and easier to access than your personal computer ‘s long-run memory ( storage, e.g. an SSD or hard tug ), but it ‘s besides temp .
This is where the personal computer stores data that it is actively using ( those “ education lists ” that the CPU needs to read and execute ). Figuring out how much RAM you need can be catchy because having more RAM than you use will do nothing ( except waste money ) while having besides short RAM will negatively affect performance .
ideally, you want the perfect come of RAM for you/your physique. by and large speaking, however, the average gambling trailer truck needs 8-16GB of RAM .
The most important thing to keep in mind when shop for RAM is what your motherboard and central processing unit can support. RAM that ‘s faster than what your system supports will downclock to run at your system ‘s capabilities .

Pro-tip : If you decide to go with high-speed RAM, count for RAM with Intel® Extreme Memory Profile ( Intel® XMP ) accompaniment. high-speed RAM will run at a standard ( lower-than-advertised ) accelerate unless it ‘s overclocked, and Intel® Extreme Memory Profile ( Intel® XMP ) makes this comfortable to do with predefined and test profiles .
Graphics Processing Unit (GPU)
There are two types of graphics processors : Integrated and discrete .
Integrated graphics processors are integrated with the CPU. Integrated graphics have improved significantly throughout the years, though they are still generally less potent than discrete graphics .
Discrete graphics cards are large, brawny components that plug into the motherboard via PCIe*, and come with their own resources, including television memory and ( normally ) an active cooling system system. A discrete graphics menu is a must-have for gamers who play any of today ‘s demand, graphics-heavy games. serious gamers will want to look for graphics cards that produce consistent frame rates of at least 60 frames per second ( FPS ) at your coveted resolution ( anything lower may look choppy ), while gamers looking to play in virtual reality should look for cards that produce consistent inning rates of at least 90 federal protective service .
Pro-tip : The GPU is n’t the merely part that affects skeletal system rate, so it ‘s significant to balance out your build or you ‘ll run into performance bottlenecks elsewhere .
Pro-tip : High-end graphics cards are expensive. If you need to cut costs, look to the last generation — the previous generation ‘s GPU may offer exchangeable results at a lower price point.

Storage: Solid-State Drives (SSDs, Including Intel® Optane™ Memory), Hard Disk Drives (HDDs)
There are two chief types of storage : solid-state drives ( SSDs, including Intel® Optane™ Memory ) and hard harrow drives ( HDDs ). There are pros and cons to choosing either an SSD or HDD, though the good news program is that you do n’t have to choose precisely one .
HDDs store data on a spin phonograph record. These platters use magnetic material to store data, which is subsequently retrieved with the consumption of a mechanical arm .
HDDs come in two form factors :
- 2.5 inches, which are more common in laptops and usually spin at a rate of 5400 RPM (revolutions per minute)
- 3.5 inches, which are more common in desktops and spin at faster rates, often upwards of 7200 RPM
SSDs use NAND-based ostentation memory — similar to, but faster and more reliable than the flash memory used in a USB flash drive — to store data. In stead of a mechanical arm, they use integrate processors to access stored data, making them a lot faster and less prone to mechanical failure than HDDs. The speed and convenience of SSDs come at a cost, however ; SSDs are more expensive per gigabyte than HDDs .
Modern SSDs come in two protocols :
- Serial Advanced Technology Attachment (SATA), which is the older protocol of the two and operates with higher latency and lower peak bandwidth
- Non-Volatile Memory Express* (NVMe*), which uses the PCI Express* interface to achieve higher performance
In accession to traditional SSDs and HDDs, there ‘s besides an option that helps bridge the speed gap : Intel® Optane™ memory repositing acceleration. Intel® Optane™ memory uses 3D Xpoint memory technology to accelerate slower drives ( chiefly HDDs ) by storing frequently used data and access patterns. Intel® Optane™ memory learns which games you use most much and uses that datum to boost game launch and level cargo times .
Pro-tip : You do n’t have to pick one. many people use a small SSD as a boot drive ( for the operate arrangement, games, and early programs ) and fill the rest of their bays with cheap HDDs for maximum storage capacity .
Power Supply Unit (PSU)
Selecting a world power issue unit ( PSU ) is a critical measure in any physique. The PSU needs to be well-made and herculean adequate to handle all current and future components, and it does n’t hurt to have a guarantee .
PSUs come in non-modular, semi-modular, and full-modular styles .
- Non-modular PSUs have all cables permanently attached. This is the cheapest option, but you’ll need to find a place to store all the cables that you know you’re not going to use. Too many unused cables result in poor cable management, which can obstruct airflow and end up affecting your PC’s performance.
- Semi-modular PSUs are the best option for most people. These units come with a handful of essential cables attached and are cheaper than full-modular styles.
- Full-modular PSUs are even easier to work with than semi-modular PSUs, but the added convenience usually comes shouldered with a higher cost.
System Cooling – CPU Cooling and Chassis Airflow
There are two chief ways to cool your personal computer : Air cooling and liquid cooling .
Air cooling uses fans to funnel blistering air through your system and aside from components to prevent overheating. The main benefits of air cooling are cost and ease-of-installation ( fans are smaller and easier to fit inside a crowd chassis ). The biggest drawback to air cool is its limitations : Air cooling depends on efficient airflow inside the font to move hot air off from components, so any airflow restriction can be debatable .
Liquid cooling uses a liquid coolant ( such as distill body of water ) to soak up heat from components and move it to an area that ‘s less restricted ( where the radiator is placed ). Liquid cool is less dependant on airflow inside the chassis, and consequently more efficient at cooling specific components. The downside to liquid cooling is that liquid cooling systems are contained, which means they ‘re normally larger and more difficult to install than a typical air-cooled apparatus ( they ‘re besides more expensive ) .
In addition to general system cool, you ‘ll besides need to purchase a give CPU cooler. CPU coolers come in both air out and liquid shape factors and mount immediately onto your CPU. When shopping for a CPU cool, it ‘s important to make certain it ‘s compatible with your CPU and sized to fit your build up .
Pro-tip : In an air-cool arrangement, more fans does not necessarily mean better cool. Fan timbre and placement make a difference .
Monitors, keyboards, mouse, headphones, and other peripherals largely come down to personal preference. You do n’t need to purchase these items with your components, but you will need a display, a keyboard, and a mouse to set up your organization after you build it .
Pro-tip : Keep build remainder in mind when picking peripherals — if you ‘ve got the best components in the worldly concern but you ‘re hush using a 1080p, 60Hz monitor, you wo n’t be taking full advantage of your hardware.
Operating system (OS)
end but not least, you ’ ll necessitate to prepare to install an operate system once all the other components have been assembled in the case. An manoeuver arrangement is a critical firearm of software that assists in managing communications between a computer ’ sulfur hardware and programs .
To prepare your personal computer ’ s OS ahead of time, determine which OS you want to install on your personal computer and download the installer on a USB dart drive. You can download the installer for Windows* 10 here. If you are installing a paid OS such as Windows, you will need a merchandise samara .
