## 1. Hardware Compatibility Engine Rules

PCBuilderX implements deterministic validation across all interconnected PC components:

### A. CPU & Motherboard Socket Compatibility
- **AMD Socket AM5 (LGA1718):** Supports Ryzen 7000, 8000G, and 9000 series CPUs. Requires DDR5 RAM. Chipsets: A620, B650, B650E, X670, X670E, X870, X870E.
- **AMD Socket AM4 (PGA1331):** Supports Ryzen 1000 through 5000 series CPUs. Requires DDR4 RAM. Chipsets: A320, B350, B450, X370, X470, B550, X570.
- **Intel Socket LGA1700:** Supports Intel 12th (Alder Lake), 13th (Raptor Lake), and 14th (Raptor Lake Refresh) Gen Core CPUs. Supports either DDR4 or DDR5 depending on the specific motherboard model. Chipsets: H610, B660, H670, Z690, B760, H770, Z790.
- **Intel Socket LGA1851:** Supports Intel Core Ultra 200S (Arrow Lake) series CPUs. Requires DDR5 RAM. Chipsets: Z890, B860, H810.

### B. Form Factor Hierarchy & Case Clearance
- **Motherboard Form Factors:** Extended-ATX (E-ATX) > Standard ATX > Micro-ATX (mATX) > Mini-ITX (mITX).
  - A case supporting E-ATX typically supports ATX, mATX, and mITX.
  - A case supporting mATX supports mATX and mITX, but cannot fit ATX.
- **GPU Length Clearance:** Case maximum GPU length must exceed the physical length of the graphics card (including front radiator/fan thickness if front-mounted).
- **CPU Cooler Height Clearance:** Tower air cooler height must be less than or equal to the case's maximum CPU cooler clearance.
- **Liquid Cooling / Radiator Support:** Radiator sizes (120mm, 240mm, 280mm, 360mm, 420mm) must match case top/front/side mounting locations, ensuring no collision with high-profile motherboard heatsinks or RAM heat spreaders.

### C. Power Supply (PSU) & Wattage Calculation
- **Estimated System Wattage Formula:**
  $$\text{System Wattage} = \text{CPU Max TDP/PL2} + \text{GPU TGP} + \text{Motherboard (50W)} + \text{RAM (5W/stick)} + \text{Storage (10W/drive)} + \text{Fans/RGB/Pump (30W)}$$
- **Recommended PSU Overhead:**
  - Standard builds: Estimated Wattage $\times 1.25$ to $1.30$ (25-30% headroom).
  - Transient spike protection (High-end GPUs like RTX 4080/4090 / RX 7900 XTX): Minimum 850W-1000W with ATX 3.0 / PCIe 5.0 12VHPWR (12V-2x6) native connector.

### D. Memory (RAM) Validation
- **DDR4 vs DDR5:** Physically incompatible keying. Motherboard and CPU memory controller must match RAM standard.
- **Dual-Channel vs Quad-Channel:** Best gaming performance requires 2 or 4 matched sticks installed in paired DIMM slots (A2/B2 configuration on 4-slot motherboards).
- **Sweet Spot Speeds:**
  - AMD AM5: DDR5-6000 MHz CL30 (1:1 IF ratio).
  - Intel LGA1700 / LGA1851: DDR5-6400 to DDR5-7200 MHz.
  - AMD AM4: DDR4-3600 MHz CL16 or CL18.
