Ideal Motherboards for I7 8700k – A Simple Buyer’s Guide

The motherboard is the most integral part of your computer system build. It creates a platform upon which the various components communicate and offers a wide variety of connectors for CPU, storage, and GPU.

Before settling on any particular motherboard, you have to make sure it meets your needs for today and the future. Here are the factors to consider when picking your motherboard;

The CPU Socket

In this case, the platform (Intel or AMD) is not a major consideration as we’re focusing solely on Intel processors and in particular i7 8700k.

Before all else, think about the CPU you plan to pair with your mainboard. A motherboard features CPU socket designed to work with a particular chip line only.

CPUs feature various socket types. LGA 1150 sockets support a wide range of Intel processors, including Celeron, i3s up to i7s. The latest Intel 8th Gen Core processors use LGA 1151v2 sockets. In short, the board you select must match the processor’s socket.

Form Factor

Motherboards come in three main sizes – ATX, Micro-ATX and Mini-ITX. Understand that Mini-ATX is the smallest.

The larger the motherboard is, the more components it can support. Be sure to check that your case has enough space to fit your motherboard.

And while the micro and min motherboards models will fit smaller chassis, it will mean settling for a reduced number of connectors such as PCIe slots, and RAM banks.

GPU Support

Almost every Intel motherboard comes with integrated GPU that offers a means to output visual information on the display. If you run less graphic-demanding tasks, then the already-integrated GPU will work just fine. 

But if you do video editing, gaming or graphics design, which demand high-level visual accuracy, then the integrated motherboard may not support these. Know the types and number of aftermarket GPUs the motherboard can support for the intended purpose.

Plans for Overclocking?

If you plan to overclock, the Z370 chipset motherboards we recommend are your best bet. But for CPUs with higher clock speeds, a high-end motherboard with enhanced cooling features will come into play.

The Expansion Slots

You’ll come across two expansion slots – the shorter PCIe x1 slots (expands SATA, USB, etc.) and the longer PCIe x16 for expanding GPUs and Raid cards. If you plan to plug multiple drivers and cards into the system, then consider a high-end ATX or even a micro-ATX motherboard.

Number of Ports

Don’t forget to check the I/O area of the motherboard to make sure it has the external connection interfaces you need. Motherboard support interfaces for USB 2.0, USB 3.0, USB 3.1 Gen 1, USB 3.1 Gen 2 and USB Type–C.

If you plan on using integrated graphics, check that the mainboard has incorporated HDMI/DisplayPort video out. For headphones and speakers, audio ports should be present. PS/2 ports will help with connect old keyboards and mice.

While it's rare to find a motherboard with Thunderbolt 3, some boards are designed to support it through dedicated add-on cards. Thunderbolt 3 allows for fast connections up to 40Gbps.

Integrated Add-Ons

Wireless networking and Bluetooth connectivity are two crucial considerations. The motherboard should come with these features already soldered so that drivers are all you’ll need to get running.

The Bottom Line                  

If you’re a build enthusiast or are looking to overclock your existing Intel i7 8700k processor, a powerful Z370 is not optional. There are lots of aspects to consider when choosing a motherboard. The socket type, form factor (size), possibility of overclocking, port options and expansion slots are just a few of those. We hope you’ve identified an excellent motherboard that will work best with your i7 8700k CPU.
