PC Parts Explained
Practical explanations designed to help you understand, troubleshoot and safely improve a gaming PC.
What does a CPU do in a gaming PC?The CPU runs game logic, simulation, draw-call preparation and background work. Strong per-core performance is especially important for high-refresh gaming.What does a GPU do in a gaming PC?The GPU renders the game image. Resolution, visual quality, ray tracing and high-resolution textures can dramatically increase graphics workload.What does RAM do for gaming?System memory holds active game and application data. Insufficient capacity can cause stutter, paging and poor multitasking.What does a motherboard do?The motherboard connects the CPU, RAM, GPU, storage, power and peripherals while determining many compatibility and expansion options.What does a power supply do?The PSU converts wall power and supplies stable power to every PC component. Quality, connectors and transient capability matter alongside wattage.SSD and NVMe storage explainedSSDs dramatically improve boot and loading times compared with hard drives. NVMe drives use PCIe and can offer much higher sequential throughput.PC cooling explainedCPU coolers, GPU coolers and case airflow remove heat so components can sustain performance without thermal throttling.PC cases and airflow explainedA case determines component clearance, airflow, radiator support, motherboard form factor and cable-management space.
