The fun part about DIY computer assembly is picking each component individually based on your preferences, needs, and budget to create a personalized machine. The launch of the 8th generation of Intel Core processors and 300 series motherboard has taken performance to a whole new level. So when selecting components for a personalized computer, aside from choosing the latest platform, many users will find that the expandability of conventional (ATX) motherboards and computer casing is not especially practical. People are often unaware that their computers have an extension function until they need to repair or upgrade their machines. A large PC case also takes up a lot of space, so choosing smaller components when building a new computer can often better meet user requirements. This article gives an overview of the latest high-performance computer components to help you choose a computer that looks good, meets your size requirements, performs well, and matches your budget.


1. Processor: Intel Core i5-8400

The processor is a computer's most important component. It directly impacts computer performance.

This requires a minimum clock speed of 2666MHz and a minimum of two 8GB memory sticks for a total of 16GB. We recommend DDR4 memory from the CORSAIR Vengeance LPX series. This series supports Intel’s XMP 2.0 automatic overclocking technology and uses a mere 1.2V of power. A low profile design takes up less space. Each memory module is 8-layer PCB design and highly-screened memory ICs with a pure aluminum heat sink, and the stability and capacity must meet rigorous quality requirements.



4. Power Supply: CORSAIR CX550

The CORSAIR CX550 is an 80 Plus Bronze certified 550-watt power supply. The power conversion rate is over 84% at full load and up to 88% when the system load drops to 50%. With its wattage and power conversion rate, users will have no problem upgrading to an Intel Core i7 and NVIDIA GTX 1080 graphics card in the future.

A single +12V output provides up to 45.8A of current, and the CPU power connector uses a 4+4 Pin. There are two PCI-E 6+2 connectors for dual Graphics Cards setup, and up to 5 cables for SATA  devices, allowing greater possibilities for Hard Drive expansion. The power cords are also wrapped to make them easier to organize. High-quality Japanese components are used on the interior of the CX550 to help ensure that the system operates stably. A 12cm fluid dynamic bearing fan spins at 2050RPM, and features temperature control functions that keep it quiet, even at full speed.




5. SSD (Solid State Drive): CORSAIR Force MP500 240GB

Solid State Drives (SSD) perform much better than conventional hard drives. If your budget permits, in addition to storing data on a conventional hard drive, you should consider buying an SSD to install your computer's OS and experience the incredible speed that SSD has to offer. The 240BG CORSAIR Force MP500 is an excellent choice in terms of price and capacity. This series is designed for the dimensions of the M.2 2280, and can be plugged directly into the new generation motherboards supporting M.2 interface. It is perfect for building small, high-performance computers.

The SSD comes with PHISON's P25007-E7 NVMe controller with 8-channel transfer speeds. It supports PCle Gen 3.0 x 4 high-speed bandwidth and is paired with TOSHIBA 15nm MLC NAND memory chips. It reads at a maximum speed of 3,000MB/s, writes at a speed of 2,400MB/s, and has a reading speed of up to 250,000 IOPS and 4K Random IOPS performance can reach 210,000 IOPS. Its excellent performance specifications greatly reduce the time required to boot the computer, load games, open applications, and transfer files.

We recommend buying an additional conventional 7200RPM mechanical Hard Drive with at least 1TB of capacity for storing other general information and games that you play less regularly pair this with a current-generation Intel 300 series motherboards. The B360M MORTAR has two M.2 slots that can support the latest Intel Optane Memory acceleration technology, vastly increasing your mechanical hard drive's performance.
