MSI Z390-A Pro: Best budget motherboard for i5-9600K

When it comes to budget motherboards for the i5-9600K, there are a lot of great choices. Our pick for the best budget motherboard for 9600K is the MSI Z390-A Pro. This board features a solid collection of features but also a VRM (voltage regulating module) good enough to host the i9-9900K, let alone the i5-9600K.
The MSI model supports DDR4 memory up to 4000 MT/s. Storage-wise you’ve got one M.2 slot in combination with six SATAIII connectors. The MSI Z390-A Pro also packs an additional M.2 slot that can host a Wi-Fi module, which could be a big plus for users who need the wireless capability.
The main PCIe x16 slot works at x16 speed while the secondary works at x4. Other expansion slots include four PCIe x1 slots.
The Realtek ALC892 Codec is powering the audio section. Connection options are limited to the included Gigabit LAN port.

ASUS Prime Z390-A: Best mid-range motherboard for i5-9600K
Next, we have the best mid-range board for the 9600K. The ASUS Prime Z390-A can handle the i9-9900K without issues. Design-wise, the ASUS model features a slick white and gray design that’s quite pleasant to the eye.
The ASUS board supports 4266 MT/s DDR4 memory, and it packs two M.2 slots and six SATA III connectors. The motherboard comes with 3 PCIe x16 slots. The primary one runs at x16, secondary at x8 (x8/x8 mode in Crossfire/SLI), and the tertiary at x4 speed. There are also three PCIe x1 slots present in case you need even more expansion slots.
Intel Gigabit LAN is present as the main connectivity option. The audio section is powered by the Realtek ALC S1220A codec. On the back panel, you can find both DisplayPort and HDMI. On top of those, the ASUS Prime Z390-A includes four USB 10Gbps ports (one is USB-C), two USB 5Gbps ports, and two USB 2.0 ports.
ASUS ROG Z390 Maximus XI Hero: Best high-end motherboard for i5-9600K
The best board for 9th gen Intel CPUs is the MSI MEG Z390 Godlike. The problem is that you can get two i5 9600K CPUs along with three solid coolers for the price of one Godlike. In other words, the board isn’t worth it for this CPU. Instead, we’ve picked the ASUS ROG Z390 Maximus XI Hero as our best high-end board for the Core i5-9600K CPU.
The ROG Maximus XI Hero is a superb Z390 board. It can power the i9-9900K even on high OC clocks, so running the 9600K won’t be a problem for it. The board looks very attractive. Black PCB with lots of dark heatsinks and a couple of RGB effects are minimalistic and very pleasant to the eye.
The board can run DDR4 memory at 4400 MT/s. It packs two M.2 slots and six SATAIII ports. Graphics-wise, you get three PCIe x16 ports. One works at x16, the second works at x8 mode (x8/x8 mode works in SLI and Crossfire configuration), and the third is an x4 port. There are also three PCIe x1 ports.
Intel Gigabit LAN is also present, as well as a wireless module and a Bluetooth 5.0 module. ROG SupremeFX S1220 is responsible for the audio section. On the back panel, there’s one HDMI and one DisplayPort for multimonitor setup when using iGPU.
You get support for all kinds of RGB effects as well as other goodies such as installing BIOS from a flash drive, BIOS flashback, lots of diagnostic LEDs, and Clear CMOS and BIOS Flashback buttons on the back panel. Overall, this is an excellent board for the money, with its only (small) downside being just two M.2 slots. A third one would be great.
Gigabyte Z390 M Gaming: Best micro-ATX board for i5-9600K
There aren’t many mATX Z390 boards. For most users, the Gigabyte Z390M Gaming should be more than enough, especially for 9600K owners.

Graphics-wise, you get one PCIe x16 slot running at x16 and one PCIe x16 slot running at x4. There are also 2 PCIe x1 slots and a third M.2 slot for Intel Wireless and Bluetooth CNVi modules. You can run a multi-monitor setup from an iGPU since the board comes with HDMI and DVI ports on the back panel.
The Realtek ALC892 codec is behind the audio department, with an Intel chip powering the Gigabit LAN. Design-wise the board looks pretty darn good.
