Chưa kèm monitor + keyboard + mouse + tai nghe.

Bước 1: CPU

AMD Ryzen 7 7700X:

• 8 core / 16 thread
• 4.5 GHz base, 5.4 GHz boost
• AM5 socket (next-gen future-proof)
• Multi-thread mạnh cho streaming + render

Lựa chọn khác:

• Intel Core i5-13600K (Newer): 14 core (6P + 8E) — gaming nhỉnh hơn, multi-thread tương đương
• AMD Ryzen 5 7600X (rẻ hơn 1.5-2tr): 6 core — đủ gaming 99%

Bước 2: GPU

RTX 4060 Ti 8GB:

• DLSS 3 support
• Ray tracing
• 1440p 100-144fps AAA medium-high
• 1080p 144+ fps high

Lựa chọn khác:

• RTX 4070 (12-13tr): 1440p 144fps high — tốt hơn 30%
• RX 7700 XT (10-11tr): AMD alternative — raw performance tốt hơn 4060 Ti, không DLSS
• RTX 3060 Ti (cũ, 7-8tr): 1440p 100fps medium — budget option

Bước 3: Motherboard

B650 chipset (AM5):

• ASUS TUF Gaming B650-Plus (3-3.5tr)
• MSI Pro B650-P WiFi (3-4tr)
• Hỗ trợ DDR5
• M.2 NVMe 4.0
• Wi-Fi 6 (some)

Tránh: A620 (cheap) — không OC RAM, không Wi-Fi.

Bước 4: RAM

32GB DDR5 6000MHz CL30:

• G.Skill Trident Z5 (3-4tr)
• Corsair Vengeance DDR5 (3-3.5tr)
• 2 stick 16GB (dual channel)

Why 32GB:

• Gaming AAA 2026 — 16GB sometimes insufficient
• Multi-task (game + Discord + Chrome + OBS) — 32GB sweet spot

Why DDR5 6000MHz:

• Sweet spot performance/price
• AMD AM5 optimal ở 6000MHz CL30

Bước 5: SSD

1TB NVMe PCIe 4.0:

• Samsung 980 Pro 1TB (2.8-3.2tr)
• WD Black SN850X 1TB (2.5-3tr)
• Crucial T500 1TB (2-2.5tr) — value option

Why PCIe 4.0:

• Read 7000MB/s vs SATA 550MB/s
• Game load 2-3x faster
• DirectStorage support (Windows 11)

Storage strategy:

• 1TB NVMe cho OS + games
• 2TB HDD external 1.5-2tr cho backup + media (optional)

Bước 6: Case

Mid-tower Mesh Front:

• Lian Li Lancool 216 (1.5-2tr): Mesh + good airflow
• NZXT H7 Flow (2-2.5tr): Premium build
• Corsair 4000D Airflow (1.8-2.2tr): Cable management tốt

Why mesh:

• Airflow tốt cho CPU + GPU
• Tản nhiệt better than glass-only

Bước 7: PSU

750W 80+ Gold:

• Corsair RM750e (1.8-2tr): Modular, 10-year warranty
• EVGA SuperNOVA 750 G6 (2-2.2tr): Pro grade
• Cooler Master MWE Gold 750 (1.5-1.8tr): Budget option

Why 750W Gold:

• Đủ cho RTX 4070 + Ryzen 7 (peak ~500W)
• Headroom cho upgrade future
• Gold efficiency tiết kiệm điện 80%+

Why modular:

• Chỉ gắn cable cần thiết
• Clean build, cable management dễ

Bước 8: Cooling

AIO 240mm:

• Arctic Liquid Freezer III 240 (2-2.5tr): Best value
• Corsair iCUE H100i Elite (3-3.5tr): RGB premium
• Deepcool LT240 (1.8-2.2tr): Budget

Why AIO 240mm:

• Đủ cool cho Ryzen 7 7700X dưới load
• Quieter than air tower (Noctua D15)
• Aesthetics modern build

Alternative air:

• Noctua NH-D15 (2.5tr): Quiet, no maintenance
• Thermalright Peerless Assassin 120 SE (700-900k): Budget value

Build Quy Trình

Bước 1: Lắp CPU vào motherboard (cẩn thận pin AM5).

Bước 2: Apply thermal paste lên CPU (pea-sized).

Bước 3: Lắp cooler (AIO radiator lên top hoặc front).

Bước 4: Lắp RAM (2 stick vào slot A2 + B2 cho dual channel).
