Shopping Tips For Motherboards
There are a lot of motherboards on the market today with i9-9900k chipsets, so it’s tough for us to select just five from them. When one searches for the best motherboards for the i9 9900K, there are several factors to consider. There are several factors that can complicate matters if you are looking to maximize the value of your motherboard investment for a gaming or creation-centric PC. It is equally important to avoid spending an arm and a leg just to upgrade your motherboard. The following factors should be considered before purchasing a motherboard.
In a buying process, the very first decision will be your choice of CPU. AMD and Intel, two of the biggest names in the processor world, use different motherboards with different sockets and chipsets. As of writing, AMD is using AM4 motherboards with LGA 1200 sockets from Intel. For your CPU and motherboard to work together right out of the box, it is critical to judge the compatibility factor beforehand.
VRM and Power Delivery
Though this is a bit more geared towards advanced users, it is still very important to keep in mind before purchasing a motherboard for an enthusiast-class CPU like the i9 9900K. The motherboard’s VRM, or power delivery system, is responsible for converting the direct power from the wall into usable, clean and stable phase power for the CPU. To get the best overclocking performance from high-end CPUs, the VRM design is absolutely critical, and its importance should never be underestimated. The thermal performance of the VRM components is also a determinant of their performance. Despite the fact that Phase Power and Power Delivery would require separate topics, don’t ignore these factors, because Phase Power and other key points mentioned here determine the fate of the project.
Desktop motherboards usually come in 3 different sizes, and they correspond with the different sizes of cases available on the market. A variety of mid-tower and full-tower cases support the ATX form factor, which is the most common and standard size. The Micro-ATX style is slightly smaller than the ATX style and fits in the majority of compact, mid-tower, and full-tower cases.
In addition to these factors, there are several others that are important to consider when choosing a motherboard for your system. See our comprehensive motherboard buying guide for a comprehensive look at the various factors that should influence your decision.
All of these are the best motherboards for the i9 9900k, and you can choose any of these according to your budget. The Gigabyte Z390 Aorus Pro is an affordable and feature-rich option, while MSI MEG GODLIKE Z390 is a sturdy and expensive option. Getting motherboards for this processor does not make sense; save that money for graphics cards or dual GPUs.
Frequently Asked Questions
Even today, this is one of the fastest gaming processors available. The processor may not be topping the charts in every game anymore due to subsequent CPU generations, but it can still pack a punch even on the most powerful systems. Despite the latest GPUs such as the RTX 3000 series, gamers can expect a seamless performance transition between the Core i9 9900K and the GPU without any hiccups.
There are two chipsets that support full overclocking capabilities, namely the Z390 and Z370 on the high end (MSI Z370 Review). Intel 9900K is also supported by chipsets like the midrange Intel Q370, B365, B360, H370, and H310, which are considered the best budget-oriented options in motherboards. It is best to stick to the Z370 or Z390 when buying a motherboard for the i9 9900K since this CPU is exceptionally good at overclocking, which can only be achieved on fully unlocked Z-series motherboards.
AMD Ryzen 9 3900X and Core i9 9900K are two fantastic CPUs, but they differ in a few ways that make them appealing to different types of buyers. As a result, if you are building a PC specifically for gaming, you should prioritize the 9900K over the 3900X. However, the Ryzen 9 3900X has 12 cores, 24 threads, and is much faster for productivity tasks, including editing and streaming. Therefore, it is important to consider your workload when choosing between the two processors.
Yes, the Intel i9 9900K processor is still perfectly viable for high-end gaming PCs in 2023. Intel’s and AMD’s latest processors may appear to be faster on paper, but in reality, it’s difficult to notice the small advantage those CPUs have over the 9900K. As a bonus, the 9900K is also cheaper nowadays because of its age, so it is a great choice for gamers looking for a high-end gaming processor but don’t quite have the budget for an Intel 11900K or AMD 5900X. Visit our guide on why i9 9900k is a bad value proposition. This may be helpful to you when making a purchase decision.
Intel’s B series chipsets are generally targeted at the mid-range or budget segments of the market, which makes them a poor fit for premium CPUs like the i9 9900K. If you choose a motherboard with the B365 chipset for this enthusiast-class CPU, you give up a lot of features, the most notable being the lack of overclocking support. FAs a result, the B series motherboards are often constructed to save money, and they use inferior quality VRM components, which will negatively affect your CPU’s performance over time.
