offers excellent value; Ryzen 7 7800X3D leads pure gaming performance.

Intel 13th/14th Gen (LGA 1700): Mature platform supporting both DDR4 and DDR5. Core i5-13600K
provides outstanding mid-range value; Core i7-14700K satisfies enthusiast needs.

Motherboard Selection

The motherboard connects all components and determines available features. Select based on required functionality
rather than premium features you won’t use.

Chipset Tiers: Higher chipsets (AMD X670E, Intel Z790) offer more features and overclocking
capability. Mid-tier chipsets (AMD B650, Intel B760) satisfy most users at lower cost.

Form Factor: ATX provides maximum expansion; Micro-ATX reduces size with minor feature reduction;
Mini-ITX enables compact builds with significant compromises.

Memory Selection

Gaming PCs in 2026 benefit from DDR5 memory, though DDR4 remains viable for Intel builds seeking budget optimization.

Capacity: 16GB provides adequate gaming headroom; 32GB suits streamers, content creators, and
future-proofing.

Speed: DDR5-5600 to DDR5-6000 offers optimal performance/price balance. Faster speeds provide
diminishing returns.

Storage Selection

NVMe SSDs are essential for modern gaming. Secondary storage can be slower/cheaper for game libraries.

Primary Drive: 1TB Gen4 NVMe SSD ($80-100) provides fast Windows and primary game storage.

Secondary Storage: Additional 2TB drives ($120-150) for expanded game libraries. Gen3 NVMe or SATA
SSDs suffice for secondary storage.

Power Supply Selection

Quality PSUs protect expensive components and ensure stable operation. Don’t cheap out on power supplies.

Wattage: Calculate total system draw and add 20-30% headroom. Most gaming builds need 650-850W.

Efficiency: 80+ Gold certification indicates good efficiency and typically quality construction.

Modularity: Fully modular PSUs simplify cable management by using only required cables.

Case Selection

Cases affect cooling, build experience, and aesthetics. Prioritize airflow and build quality over pure aesthetics.

Airflow Design: Mesh front panels allow better cooling than solid panels. Adequate fan mounting
points enable effective airflow configuration.

Size and Clearance: Verify GPU length, CPU cooler height, and radiator support match your component
selections.

CPU Cooler Selection

Stock coolers suffice for some CPUs but aftermarket coolers provide better thermals and acoustics.

Air Coolers: Tower coolers like Noctua NH-D15 or DeepCool AK620 provide excellent cooling at
reasonable cost.

AIO Liquid Coolers: 240mm-360mm AIOs offer strong cooling with cleaner aesthetics but higher cost
and minimal performance improvement over quality air coolers.

III. Preparing for Assembly

Proper preparation ensures smooth assembly. Gather tools and prepare your workspace before beginning.

Required Tools

• Phillips-head screwdriver (magnetic tip helpful)
• Anti-static wrist strap (optional but recommended)
• Good lighting
• Clean, static-safe workspace
• Cable ties for cable management
• Smartphone/tablet for reference guides

Workspace Preparation

Clear a large, clean surface—ideally a non-carpeted area to reduce static electricity. The motherboard box makes an
excellent anti-static work surface for external assembly.

Avoid assembling on carpet or wearing clothing prone to static generation. Touching a grounded metal object before
handling components discharges static buildup.

Component Organization

Unbox components and organize accessories. Identify included screws, cables, and mounting hardware. Reading
motherboard and case manuals before assembly prevents confusion during the build.

IV. Step-by-Step Assembly Process

Follow this sequence for efficient assembly. Some steps may vary based on your specific components.

Step 1: Install CPU

Begin with CPU installation on the motherboard outside the case. This provides clear access and visibility.

Intel LGA 1700: Release the retention bracket. Align the CPU with socket markers (golden triangle
matches socket triangle). Place the CPU gently—it drops into position without force. Close the retention bracket,
which will push out the protective cover.

AMD AM5: Lift the retention lever. Align the golden triangle on the CPU with the socket marker.
Place the CPU into the socket—pins align automatically. Close the retention lever.

Handle CPUs by edges only. Never touch the contact pads (Intel) or pins (AMD).

Step 2: Install RAM

Install memory in the correct slots for dual-channel operation. Check your motherboard manual for optimal slot
configuration (often A2 and B2 for two sticks).

Open memory slot latches. Align the RAM notch with the slot key. Press firmly until latches click closed. RAM
requires surprising force—don’t be afraid to press firmly with even pressure.

Step 3: Install M.2 SSD

Remove the M.2 heatsink if present. Insert the SSD at an angle into the M.2 slot, then press down and secure with the
mounting screw. Replace the heatsink if applicable.

Step 4: Install CPU Cooler

Apply thermal paste to the CPU if not pre-applied on the cooler. A pea-sized dot in the center spreads during
mounting pressure.

Follow your cooler’s specific mounting instructions. Tighten mounting screws in a cross pattern for even pressure.
Connect the fan header to the CPU_FAN motherboard connector.

Step 5: Prepare the Case

Remove case panels for access. Install the I/O shield if your motherboard includes a separate piece (many modern
motherboards integrate this). Install standoffs matching your motherboard form factor if not pre-installed.

Step 6: Install Motherboard

Lower the motherboard carefully into the case, aligning screw holes with standoffs. Secure with motherboard mounting
screws—snug but don’t overtighten.

Step 7: Install Power Supply

Mount the PSU in the case’s designated location (usually bottom-rear). Orient the fan facing the ventilated direction
(down if case has bottom venting, up otherwise).

Connect power cables to the motherboard: 24-pin main power, 8-pin CPU power. Route other cables toward their
destinations but don’t connect yet.

Step 8: Install Graphics Card

Remove necessary PCIe slot covers from the case rear. Press down on the PCIe slot retention clip.

Insert the GPU firmly into the primary PCIe x16 slot until the retention clip clicks. Secure the bracket to the case
with screws. Connect PCIe power cables from the PSU.

Step 9: Connect Case Cables

Connect front panel connectors to motherboard headers: Power button, Reset button, Power LED, HDD LED. Refer to your
motherboard manual for exact pin locations.

Connect USB headers, audio headers, and any case fan connections. Modern cases often include labeled cables
simplifying this process.

Step 10: Cable Management

Route cables behind the motherboard tray where possible. Use cable tie points in the case. Group cables by type and
destination. Good cable management improves airflow and aesthetics while making future maintenance easier.

V. First Boot and Setup
