Why Build Your Own?
Building a gaming PC is easier than you think, saves 15-30% vs prebuilts, and gives you exactly the specs you want. This guide walks you through every step, from choosing parts to first boot.
The $1,200 Sweet Spot Build
CPU: AMD Ryzen 7 7800X3D ($329) — best gaming CPU, period. 3D V-Cache delivers unmatched gaming performance. GPU: AMD RX 9700 XT ($549) — excellent 1440p performance, great value. Motherboard: MSI B650 Tomahawk WiFi ($179) — solid VRMs, WiFi 6E, USB-C front panel. RAM: 32GB DDR5-6000 CL30 ($89) — sweet spot for AM5 platform. Storage: 2TB PCIe Gen 4 NVMe ($109) — fast enough for gaming, great price per GB. PSU: Corsair RM750e ($89) — 80+ Gold, fully modular, 750W handles this build with headroom.

Assembly (About 2 Hours)
Step 1: Install CPU into motherboard socket — lift retention lever, align triangle markers, gently place (zero force), close lever. Step 2: Install RAM in slots 2 and 4 (from CPU), push until clips click. Step 3: Install M.2 SSD in the top M.2 slot, secure with screw. Step 4: Mount CPU cooler with thermal paste (pea-sized dot center of CPU). Step 5: Install motherboard into case using standoff screws. Step 6: Install PSU in case bottom, route cables through back panel. Step 7: Install GPU in top PCIe x16 slot, connect 8-pin power cables. Step 8: Connect front panel cables (USB, audio, power button) per motherboard manual. Step 9: Cable management — route excess cables behind the motherboard tray.
First Boot
Power on, enter BIOS (Delete key), enable XMP/EXPO for RAM speed, set boot order to USB. Install Windows 11 from USB drive. Install GPU drivers from AMD.com. Update motherboard BIOS and chipset drivers. Install games and enjoy.
Common Mistakes to Avoid
Don’t forget to connect the CPU power cable (top-left of motherboard). Don’t force RAM — it only goes one way. Use standoff screws before mounting the motherboard. Don’t cheap out on the PSU — it protects everything else.
