How We Tested & Picked These Motherboards For i9-12900K
These are the vital factors to keep in mind when you’re in the process of buying a motherboard.
- Chipset: Firstly, you should look for a compatible chipset for your processor. You can go to the vendor’s website and look for a well-suited chipset. As for Intel, all 12th-generation processors support 600 series chipsets, including Z690, H670, B660, and H610. Z690 is the most premium chipset with exclusive support for CPU overclocking.
- VRM: The i9-12900k is a power-hungry CPU compared to the other processors in the series. It needs a steady and consistent power supply for competitive performance which is the motherboard’s responsibility. That’s where the VRM has its holding. The better the VRM, the more solid and steady the power, allowing the CPU to go above its limits.
- Form Factor: Before buying the motherboard, you should know the form factor and what type of build you want. Small builds and bigger builds don’t fit in the same motherboard size. There are different motherboard sizes in the market, including some popular ones like ATX, Micro ATX, and Mini-ITX.
- I/O Connectivity: For the purposes of expansion, you need USB ports and PCIe expansion slots. Different gadgets like GPUs and SSDs have compatible PCIe interfaces. You will also love having the latest USB interfaces for your PC for high-speed access, which will help improve the performance of your PC overall.
- Aesthetics: Design is personal to everyone, but you can look out for some things like the PCB color, heatsink color, and the inclusion of lightning. Motherboards can have different color PCBs and heatsinks to form a contrasty look. Along with that, there’s also support for single-colored LED or RGB in some motherboards.
Frequently Asked Questions
You can plug in your i9-12900k in any motherboard from the 600 series chipset, but it depends on the type of performance you want. If you’re going to get the best out of the i9-12900k CPU, first of all, you will need a motherboard with the Z690 chipset. However, if you want a mediocre performance, you can install it in an H670 or B660 chipset motherboard.
If you’re someone eager to get the best out of Intel’s best performance and you have the budget to spend for the best, you can go for it blindfolded. This level of upgradation will allow you to enjoy CPU overclocking and memory overclocking at its best too.
Yes there are many DDR4 supported motherboards like the ASUS Prime Z690M-Plus and the Gigabyte Z690 AORUS Elite AX DDR4. The Z690 is a transition point from DDR4 to DDR5 so many manufacturers offer motherboards with Intel 1700 sockets and DDR4 in one package.
DDR5 has different pins and cut assortment like all predecessors. So in layman’s terms, you cannot insert DDR4 RAM onto a DDR5 motherboard because there is no chance that it can be physically or logically possible.
All the RTX 3000 series GPUs are made on PCIe 4.0 standard. There is no chance for a notable boost with the PCIe 5.0 socket. The same is the case with AMD RX series GPUs.
Our testing extends to a wider array of Intel 12th Gen motherboards:
