Let‘s get started!

Determining Your PC Goals and Budget

Before picking out any parts, it‘s really important to determine what you plan to use your custom-built computer for. This will influence the types of components you‘ll need.

Here are some of the most common use cases and their hardware requirements:

Gaming: Fast processors, high-end graphics cards, quick RAM, and speedy storage
Video Editing: Lots of processing cores, ample RAM, large & fast storage
3D Modeling/CADD: Strong single-core CPU performance, workstation-level graphics, plenty of RAM

You also need to think about a budget so you can narrow down parts that offer the best bang for your buck. $800-$1500 is a common range for a high-performance gaming or creative PC. We‘ll come back to cost optimization when picking individual components.

I always recommend writing down your target applications, desired performance metrics, and overall budget. This will give us some goalposts to narrow down components.

Choosing Your PC Case, Motherboard, and CPU

The foundation of any PC build is the case, motherboard, and processor you decide to base it around.

Determining Case Size

Cases come in different sizes, which support different motherboard form factors. Full ATX cases are versatile, supporting various sizes. Smaller Micro-ATX cases save space but limit component choices. If cooling and expansion are important, larger cases are preferred.

Here is a comparison of common case sizes:

Size Motherboard Support Expansion Capability Cooling Capacity Physical Size
Full Tower E-ATX, ATX, Micro-ATX, Mini-ITX Excellent – lots of drive bays and PCIe slots Excellent – support for large air coolers and radiators Very large
Mid Tower ATX, Micro-ATX, Mini-ITX Great – Good drive bay and PCIe expandability Great- Can mount multiple fans and radiators Average size – Good versatility
Micro-ATX Micro-ATX, Mini-ITX Fair – 1-2 drive bays and fewer PCIe slots Fair – Limited radiator and fan support Compact size
Mini-ITX Mini-ITX Very limited – single drive bay, 1-2 PCIe slots Poor – Strict cooler height limits Extremely small form factor

As you can see, Mid Tower and Full Tower cases offer the most flexibility and expansion capability. I suggest sticking with one of those form factors for your first build.

Finding the Right Motherboard

Your CPU, RAM, GPU, drives, and other components will all connect to the motherboard. The socket and chipset must match your processor. You also want sufficient RAM slots, PCIe lanes, and ports for your build.

Here‘s an AMD X570 and Intel Z590 motherboard with the key specs called out:

For your first build, get a board from a reputable brand like ASUS, MSI, or Gigabyte based around a B550, X570, Z590 or Z690 chipset. This gives you room to grow and flexibility to use the latest components.

Choosing a Processor (CPU)

The CPU carries out the essential computations that enable all of your applications. Intel and AMD currently manufacture desktop CPUs. Consider core counts, clock speeds, overclocking support, power draw, and socket compatibility.

Here is a comparison table of some current-generation CPUs perfect for a custom build:

CPU Cores/Threads Base Clock Boost Clock GPU Socket Price
AMD Ryzen 5 5600X 6C/12T 3.7GHz 4.6GHz None AM4 $199
AMD Ryzen 7 5800X3D 8C/16T 3.4GHz 4.5GHz None AM4 $399
Intel Core i5-12600K 10C/16T 3.7GHz 4.9GHz Intel UHD 770 LGA 1700 $289
Intel Core i7-12700K 12C/20T 3.6GHz 5.0GHz Intel UHD 770 LGA 1700 $399

The Ryzen 5 5600X or Core i5-12600K deliver the best bang for your buck. But the 5800X3D and 12700K provide more cores and power for intensive workloads. All four processors are excellent options that will boost gaming and creative application performance.

Installing CPU Cooling Solutions

Desktop processors require dedicated cooling solutions to siphon away heat and maintain high clock speeds.

Air coolers and all-in-one (AIO) liquid coolers are the most common options. High-end air coolers actually compete with or beat mid-tier liquid cooling solutions now. Custom open-loop cooling is preferred for extreme overclocking.

Here are great air and liquid coolers for mainstream CPUs:

Air Coolers

  • Noctua NH-D15 chromax ($110) – Massive dual-tower performance
  • Thermalright Peerless Assassin 120 SE ARGB ($56) – Excellent value
  • Deepcool AK620 ($65) – Most cooling per dollar

Liquid (AIO) Coolers

  • Arctic Liquid Freezer II 280 ($100) – Quiet and powerful
  • NZXT Kraken X63 RGB ($137) – Top reputation and aesthetics
  • Corsair iCUE H150i Elite LCD ($289) – Stylish customizable LCD display

Spending around $60-$150 gets you high efficiency cooling that will support overclocking and sustain boost speeds. Always check size compatibility against your case and RAM clearance.

Installation is tool-free these days. Screw the mounting bracket to backplate, apply thermal paste to CPU, then screw cooler into top bracket. Enable fan control in BIOS and you‘re done!

Selecting High-Performance RAM

Just like a CPU, RAM provides critical working memory for active applications and workloads. Two sticks for dual-channel operation delivers the best real-world performance.

For modern builds, you‘ll likely want 16GB or 32GB of DDR4-3200, DDR4-3600, or DDR5-5200 memory. Here is a performance and value analysis across those options:

Memory Standard Speeds Performance Price per 16GB
DDR4-3200 3200MHz Good $50-60
DDR4-3600 3600MHz Better $75-90
DDR5-5200 5200MHz+ Best $110-$150

While DDR5 promises higher frequencies, most real-world applications see limited benefit versus faster DDR4 options right now. But DDR5 does offer future upgradability.

Here are some great DDR4 and DDR5 recommendations from top memory brand Corsair:

  • Corsair Vengeance RGB Pro 16GB (2x8GB) DDR4 3600 ($89)
  • Corsair Vengeance 32GB (2x16GB) DDR4 3600 ($134)
  • Corsair Dominator Platinum RGB 32GB DDR5 5200 ($264)

Simply match the notch position and press down firmly until the retention clips click on both sides. Enable XMP profile in BIOS and you‘re set!

Understanding Internal PC Storage Solutions

There are two main types of internal drives used in modern builds – Solid State Drives (SSDs) using flash memory and traditional mechanical Hard Disk Drives (HDDs).

Here is a feature comparison:

Specs SSD HDD
Interface SATA, M.2 PCIe NVMe SATA
Sequential Read Speeds Up to 7,000 MB/s (PCIe 4.0) Up to 240MB/s
Cost Per GB Around 15¢ Around 3¢
Lifespan Higher write endurance Shorter lifespan
Size Compact 2.5" and M.2 sticks 3.5" drive bays

SSDs offer lighting quick response times and transfer speeds compared to traditional hard drives. M.2 NVMe drives connect directly to the motherboard via PCIe lanes for maximum throughput.

But SSDs come at a price premium. So most builder pair a smaller SSD (250-500GB) as the primary OS/applications drive and add a larger HDD (2-4TB) for mass storage.

Installing M.2 drives directly onto the motherboard and mounting 3.5" HDDs in drive bays could not be easier. Simply screw into place connect power/data cables and you have superfast storage ready for action!

Choosing a Graphics Card for Gaming or Creative Workloads

The GPU or graphics card plays a huge role in gaming performance and tackling creative workloads like video editing. Pick based on target display resolution, game titles, studio applications, and of course budget.

Here is how the mid-range NVIDIA RTX 3060 Ti and flagship RTX 3090 compare:

GPU Memory 1080p Performance 1440p Performance 4K Performance Price
RTX 3060 Ti 8GB GDDR6 Excellent, 100+ FPS Great, 60-100 FPS Fair, 30-60 FPS $400
RTX 3090 24GB GDDR6X Overkill Excellent, 100+ FPS Great, 60-100 FPS $1,500

Similarly, the AMD Radeon RX 6800 XT delivers performance between the RTX 3070 and 3080 for $120 less than the latter. Always check GPU benchmarks from reputable sites like Tom‘s Hardware when evaluating options.

Install into any open PCIe x16 slot, connect power connectors, install drivers and game on! Having an adequate power supply is key, which we‘ll cover next.

Choosing the Right Power Supply (PSU)

Having enough stable power to drive your entire system is critical. Efficiency ratings like 80+ Bronze through Titanium indicate how effectively units draw from the wall.

Here are the main specifications to consider:

  • Wattage – 650-850W recommended to deliver CPU/GPU peak power
  • Efficiency rating – 80+ Gold or better ideal
  • Modularity – Removable cabling helps tremendously with cable management
  • Size – Get the right form factor for your case
  • Warranty – 5-10 years of coverage preferred

Here are exceptional power supply options from Corsair, EVGA and SeaSonic. Aim for 750-850 watts from a reputable brand:

  • Corsair RM850 850W 80+ Gold Modular ($134)
  • EVGA SuperNOVA 850 GA 850 W 80+ Gold Modular ($99)
  • SeaSonic FOCUS Plus Platinum 850W 80+ Platinum Modular ($184)

Installation involves mounting it to the rear case panel and connecting just a few power cables to components. Super straightforward!

Now let‘s bring this all together and actually build our PC!
