Build Your Own Custom PC in Nepal

Key Considerations When Building a Custom PC in Nepal

Building a custom PC lets you choose every part to match your needs, but smart component choices are crucial. Use this quick guide to make informed decisions and assemble a reliable, high-performance PC in Nepal.

Processor (CPU)

The CPU is the brain of your PC, driving overall speed and responsiveness. Intel and AMD both offer strong options. For gaming and high-refresh performance, Intel’s 13th- and 14th‑gen chips (look for “K”/“KF” for overclocking) are excellent. For balanced value in mid-range builds, AMD Ryzen is a great pick, with newer Ryzen 7000/8000-series offering strong multi-core performance. For heavy content creation or workstation tasks, AMD Threadripper delivers exceptional core counts and throughput, though it’s overkill for typical gaming builds.

Motherboard

The motherboard is the hub that connects every component, so it must match the CPU’s socket and chipset. Intel and AMD use different sockets (e.g., Intel LGA1700, AMD AM5/AM4), so always verify compatibility first. Choose a board that supports the features needed for the build—PCIe 4.0/5.0 lanes for fast GPUs and SSDs, enough M.2 slots, built‑in Wi‑Fi/Bluetooth if required, adequate VRM quality for stability (especially if overclocking), and the right form factor (ATX, mATX, ITX) to fit the case.

CPU Cooling

Effective CPU cooling keeps performance stable and extends component lifespan. For everyday builds, a quality air cooler is usually enough. If planning to overclock or run heavy workloads (gaming, editing, 3D rendering), consider a 240 mm–360 mm AIO liquid cooler for better thermal headroom and quieter operation. Always check cooler compatibility with the CPU socket and case clearance, use good thermal paste application, and ensure proper case airflow (front intake, rear/top exhaust) to maintain low temperatures.

Graphics Processing Unit (GPU)

A dedicated graphics card dramatically boosts performance for gaming, video editing, 3D work, and AI workloads. While some CPUs include integrated graphics for basic use, a discrete GPU delivers far higher frame rates and render speeds. For entry-level builds, look for affordable options that fit power and case constraints; for mid-range, target GPUs that handle 1080p–1440p smoothly; and for high-end, choose cards designed for high-refresh 1440p or 4K and accelerated creator workloads. Always match the GPU to the monitor’s resolution/refresh rate, ensure the power supply has sufficient wattage and PCIe connectors, and confirm case clearance and airflow to avoid thermal throttling.

Power Supply Unit (PSU)

The power supply (PSU) feeds every component, so sizing and quality matter. Choose wattage based on the GPU/CPU’s peak draw plus headroom (typically 20–30%) for upgrades. As a quick rule: budget builds often do well with 500–600W, mid-range with 650–750W, and high-end or flagship GPUs with 850–1000W. Prioritize reputable brands and 80 Plus efficiency (Bronze as a minimum; Gold is a great sweet spot; Platinum/Titanium for ultra-efficient or compact, heat-sensitive builds). Check required PCIe power connectors, ensure ATX 3.0/3.1 and native 12VHPWR support for modern GPUs if applicable, and make sure the PSU fits the case and cable-management needs (modular or semi‑modular).

RAM

RAM is your PC’s short‑term memory and helps apps run smoothly. For everyday use, 8GB works, but 16GB is the modern baseline for gaming and multitasking. Power users, creators, or heavy browser/multitab workflows benefit from 32GB, and specialized workloads can use 64GB+. Match memory type and speed to your platform: DDR4 remains cost‑effective, while DDR5 offers higher bandwidth and better future‑proofing on newer motherboards. For best results, use a 2‑stick (dual‑channel) kit, follow the motherboard’s QVL when possible, and enable XMP/EXPO in BIOS to run at the rated speed.

Storage

Storage comes in two main types: SSD and HDD. SSDs are much faster for booting, launching apps, and game load times, while HDDs are slower but cost-effective for large files and backups. For a smooth experience, use an NVMe SSD (preferably PCIe 3.0 or 4.0) as the primary drive—1TB is a great sweet spot—and add a larger HDD (2TB–4TB) if bulk storage is needed. Check your motherboard’s M.2 slots, enable the correct PCIe mode, and leave 10–20% free space on the SSD to maintain peak performance.

PC Case

The PC case protects components and drives airflow, which directly affects temperatures and noise. A mid‑tower ATX case suits most builds, offering good space for GPUs, multiple drives, and clean cable management. If planning custom water-cooling, extra drives, or oversized GPUs, a full‑tower provides more room and better radiator support. Prioritize cases with unobstructed front intake, including quality fans, dust filters, and clear GPU/CPU cooler clearance specs. In Nepal, expect budget-friendly options around Rs 10,000, with premium airflow or tempered‑glass models costing more depending on features and brand.
