require a larger, full tower chassis. Micro-ITX boards can be accomodated in smaller chassis. Micro-ITX boards can be accomodated in smaller chassis. Users who aim to employ multi-graphics solutions will also have to take into account size, and most likely opt for larger chassis. Some extreme gaming or overclocking motherboards in fact use the largest XL-ATX form factor for which thereare reletively few compatible chassis. If you choose an XL-ATX form factor motherboard, you can check the GIGABYTE website for a list of compatible chassis models. It’s also important to understand the role the chassis will play in terms of ventilation and cooling. Most chassis come equipped with internal cooling fans, designed to maintain airflow and prevent key components from overheating. Larger chassis generally tend to offer better ventilation, while aluminum chassis designs are also optimized to maintain stability. For the majoity of PC builds, your chassis will also be influenced according to aesthetics and style, but you may also want to consider additional features such as front access to USB ports an audio jacks. The Power Supply The power is arguably the most important component in the PC, and yet it is frequently the most overlooked. Without a stable and reliable power supply, none of the other components will work at expected levels of stability. Modern power supplies follow a revamped ATX specification which offers more dedicated power for the CPU and additional power for the graphics cards. The most important features of any power supply should be realiability and effiiciency. Most GIGABYTE ODIN power supplies for example confrom to the 80% power efficiency rating and make great choice for enthusiast and upper tier gaming systems. It’s important when choosing the power supply to consider what the systems overall thermal profile will be, i.e. how many watts should your newly built PC demand? Many modern CPUs and grapics cards will push the overall power profile beyond traditional 500 Watt or 600 Watt boundries, with top tier systems demanding as much as 1000 Watt power supplies, or higher if designed for extreme overclocking.
