- 1440p: RTX 4070 Ti, RX 7900 XT
- 4K: RTX 4080/4090, RX 7900 XTX
Memory (RAM)
Fast RAM reduces latency and improves multitasking. Dual-channel DDR4 or DDR5 kits at 3200 MHz+ are recommended.
- Minimum: 16 GB
- Recommended: 32 GB for streaming, editing, and future titles
Storage
Combine NVMe SSD speed with HDD capacity for the optimal balance.
- Primary: 1 TB NVMe SSD (PCIe Gen 4)
- Secondary: 2–4 TB HDD for media/storage
Motherboard
Select a motherboard with robust VRMs, PCIe 5.0 slots, multiple M.2 heatsinks, and Wi-Fi 6E if needed.
- Form Factor: ATX for expandability, Micro-ATX for compact builds
- Features: USB C front panel, extra SATA/M.2 ports
Power Supply (PSU)
A quality PSU protects your components and delivers stable power. Look for 80+ Gold/Platinum certification.
- Wattage: 650–850 W for single GPU, 1000 W+ for dual-GPU
- Modular design for cable management
Cooling & Case Selection
Optimal airflow and cooling maintain stability under load and extend component life.
- Front intake, top/rear exhaust fans
- 120–360 mm AIO radiators or high-end air towers
- Dust filters and cable management channels
Ensuring Component Compatibility
- Check CPU socket vs. motherboard chipset
- Verify RAM height vs. CPU cooler clearance
- Confirm GPU length vs. case depth
- Ensure PSU cable reach and routing
Step-By-Step Build Process
- Prepare Workspace: Clear a static-safe area and gather tools.
- Install CPU & Cooler: Align the CPU, apply thermal paste, secure cooler.
- Insert RAM: Seat modules until latches click.
- Mount Motherboard: Secure with standoffs in the case.
- Add Storage: Install NVMe SSD, SATA drives.
- Install GPU: Seat in PCIe slot, fasten and connect power.
- Connect PSU: Route and plug in 24-pin, 8-pin, PCIe, SATA cables.
- Cable Management: Tidy cables behind tray for airflow.
- First Boot & BIOS: Verify components, enable XMP/DOCP, set fan curves.
- OS Installation: Install and update Windows or Linux, then drivers.
Post-Build Optimization
- Update BIOS, firmware, and drivers.
- Tweak GPU fan curves, power targets, and overclock offsets.
- Enable Game Mode and disable unnecessary startup apps.
- Monitor temps with MSI Afterburner or HWMonitor.
Overclocking and Advanced Tweaks
