Remember to factor in potential shipping costs and import taxes when sourcing parts from AliExpress. Also, keep an eye out for flash sales and promotional offers to stretch your budget further.

Another important aspect of budget planning is to consider used or refurbished components. While buying used parts can be risky, reputable sellers on AliExpress often offer warranties or guarantees on refurbished items. This can be a great way to save money on components like the GPU or RAM, allowing you to allocate more funds to other critical parts like the power supply or storage. Be diligent in researching the seller's reputation and reading reviews before making a purchase. Finally, don't forget to account for peripherals like a monitor, keyboard, and mouse. These can quickly eat into your budget, so consider starting with basic models and upgrading later as funds become available. Prioritize a decent monitor, as visual clarity greatly enhances the gaming experience.

Core Components: CPU and Motherboard

The CPU (Central Processing Unit) is the brain of your gaming PC, handling game logic, AI, and physics calculations. For a 2500 BRL budget, aim for a mid-range CPU that offers a good balance of price and performance. A popular choice is an AMD Ryzen processor, such as the Ryzen 5 3600 or Ryzen 5 5500, depending on availability and pricing on AliExpress. These CPUs offer excellent multi-core performance, making them suitable for both gaming and other tasks like streaming or content creation. When selecting a CPU, pay attention to its clock speed, core count, and thermal design power (TDP). Higher clock speeds generally translate to better performance, while more cores allow for smoother multitasking. The TDP indicates the amount of heat the CPU generates, which is important for selecting an appropriate cooler.

The motherboard is the backbone of your system, connecting all the components together. When choosing a motherboard, ensure it is compatible with your chosen CPU. For AMD Ryzen processors, look for motherboards with the AM4 socket. Chipsets like the B450 or B550 are good options for budget builds, offering a decent set of features without breaking the bank. Consider the number of RAM slots, PCIe slots, and USB ports when selecting a motherboard. More RAM slots allow for future upgrades, while PCIe slots are used for the graphics card and other expansion cards. Ensure the motherboard has enough USB ports for your peripherals and other devices. Check the motherboard's specifications for compatibility with the CPU and RAM you intend to use. Some older motherboards may require a BIOS update to support newer CPUs. Reputable brands like ASUS, MSI, and Gigabyte offer reliable motherboards on AliExpress.

Graphics Card (GPU): The Heart of Gaming

The GPU is arguably the most critical component for gaming. It's responsible for rendering the visuals you see on screen. Given the budget constraints, finding the right GPU requires careful consideration. Look for GPUs that offer the best performance per dollar. Options like the AMD Radeon RX 580, RX 5500 XT, or even a used RX 5700 can provide a decent gaming experience at 1080p resolution. Keep an eye out for deals on AliExpress, as prices can fluctuate significantly. The GPU's VRAM (Video RAM) is also important, as it stores textures and other graphical data. Aim for a GPU with at least 4GB of VRAM, but 8GB is preferable for more demanding games. When selecting a GPU, consider its power consumption and ensure your power supply unit (PSU) can handle it.

Before buying, research benchmarks and reviews of the GPU to understand its performance in different games. YouTube is a great resource for finding gameplay videos and comparisons. Pay attention to the resolution and graphics settings used in the benchmarks, as these can significantly impact performance. Also, check the dimensions of the GPU to ensure it fits inside your case. Some GPUs are quite large and may not fit in smaller cases. Consider buying a used GPU from a reputable seller on AliExpress. This can save you a significant amount of money, but be sure to thoroughly inspect the card upon arrival and test it extensively. Check the seller's feedback and warranty policy before making a purchase. Remember to install the latest drivers for your GPU to ensure optimal performance.

Memory (RAM) and Storage

RAM (Random Access Memory) is essential for smooth multitasking and gaming. Aim for at least 16GB of DDR4 RAM with a speed of 3200MHz or higher. This will provide ample memory for most modern games and applications. Look for reputable brands like Corsair, Kingston, or Crucial on AliExpress. Pay attention to the RAM's timings (CAS latency) as lower timings generally result in better performance. However, the difference is often negligible in real-world gaming scenarios. Consider buying a RAM kit with two modules (e.g., 2x8GB) to take advantage of dual-channel memory, which can improve performance. Check your motherboard's specifications to ensure it supports the RAM speed you intend to use.

For storage, consider a combination of an SSD (Solid State Drive) for the operating system and frequently used games, and an HDD (Hard Disk Drive) for mass storage. A 240GB or 500GB SSD is sufficient for the OS and a few games, while a 1TB HDD can store the rest of your game library, media files, and other data. SSDs offer significantly faster load times compared to HDDs, making them ideal for the operating system and games. Look for reputable brands like Samsung, Western Digital, or Crucial on AliExpress. Consider an NVMe SSD for even faster speeds, but these are typically more expensive. Ensure your motherboard has an M.2 slot to support NVMe SSDs. HDDs are more affordable for mass storage but are significantly slower than SSDs. When selecting an HDD, pay attention to its RPM (revolutions per minute) as higher RPMs generally result in better performance.

Power Supply Unit (PSU) and Case

The PSU provides power to all the components in your system. It's crucial to choose a PSU with sufficient wattage and good quality to ensure stable operation and prevent damage to your components. A 550W or 650W PSU with an 80+ Bronze certification should be sufficient for a budget gaming PC. Look for reputable brands like Corsair, Seasonic, or EVGA on AliExpress. Pay attention to the PSU's certifications (e.g., 80+ Bronze, 80+ Gold) as higher certifications indicate better efficiency. Ensure the PSU has enough connectors for all your components, including the motherboard, CPU, GPU, and storage devices. Consider a modular PSU, which allows you to detach unused cables, improving airflow and cable management.

The case houses all the components and provides cooling. Choose a case that is compatible with your motherboard size (e.g., ATX, Micro-ATX) and has good airflow. Look for cases with mesh front panels or multiple fan mounts to improve cooling. Consider the aesthetics of the case, but prioritize functionality and airflow. Reputable brands like Cooler Master, Corsair, or NZXT offer cases on AliExpress. Pay attention to the case's dimensions to ensure it fits in your desired location. Consider a case with good cable management features, such as routing channels and tie-down points. This will help keep the inside of your case clean and improve airflow. Some cases come with pre-installed fans, which can save you money. Remember to consider the noise level of the fans when selecting a case.
