Gigabyte Z390 AORUS Pro

Brand: Gigabyte | Chipset: Intel Z390 | Socket: LGA 1151 | Form Factor: ATX | Memory: 128 GB DDR4 | Memory Speed: 4133 MHz

The Gigabyte Z390 AORUS Pro  motherboard offers good performance with some nice set of features at a quite value price. The Gigabyte Z390 AORUS Pro has four DDR4 DIMM Slots. It also has two M.2 Slots and six SATA III ports. Each M.2 slot has an AORUS M.2 shield which cools it. The Gigabyte Z390 AORUS Pro has a single Gigabit port  and does not have WiFi, whereas there is a WiFi model also available which is a little bit more pricey than the motherboard that we are talking about. The Gigabyte Z390 AORUS Pro also features a Realtek 1220.

It has quite some RGB lighting, clearly Gigabyte taking a different path here. With all those aesthetics, you also get eight 4-pin hybrid fan headers. It has two M.2 slots which only differ in the size they support. The one closer to the CPU socket supports 110mm while the one further away from the CPU socket supports 80mm. Both SATA M.2 and PCIe SSDs can be used in bothe of the slots and both of the slots also have heat sinks too.

Asrock Z390 Phantom Gaming 9

Brand: Asrock | Chipset: Intel Z390 | Socket: LGA 1151 | Form Factor: ATX | Memory: 64 GB DDR4 | Memory Speed: 4266 MHz

Asrock Z390 Phantom Gaming 9 is an enthusiast-grade motherboard for the 8th and 9th generation of Intel processors and is specifically an excellent choice for the likes of Intel Core i9-9900K, providing mind-blocking overclocking features, high-quality I/O features, and a gasping design. One can easily understand the premium price of the motherboard by the first look and that is mainly due to the large I/O cover, shiny PCI-E slot, and aesthetically pleasing VRM heat-sinks. There is RGB lighting on the I/O cover along with the chipset heat-sink and the backside of the PCI-E slots. There is written PG at the chipset heat-sink, indicating Phantom Gaming while you can also find the full name of the motherboard on the PCB. The PCB of the motherboard is black in color with a bit of silver and red-colored stripes.

Now, the quality of Asrock Z390 Phantom Gaming 9 is quite similar to the likes of ASUS ROG Maximum series motherboards and that is why the VRM heat-sinks are large in size, keeping the VRM temperatures under control. Three out of five PCI-E slots are reinforced with metal and are PCI-E X16 slots while the other two are PCI-E X1 slots. There are four DIMM slots on the motherboard, limiting the maximum memory capacity to 128 GB. Apart from the 24-pin power connector and the 8-pin power connector, the motherboard allows a 4-pin power connector as well, which is located right next to the 8-pin connector. Asrock Z390 Phantom Gaming 9 is really impressive in terms of storage options, as it provides 8 x SATA III ports and three Ultra M.2 slots, which is barely seen in any motherboard. The motherboard comes with 128 MB BIOS and it even provides a backup 128 MB BIOS, in case anything goes wrong. 

The I/O of the motherboard is very surprising as well. This is one of the only motherboards that come with three RJ45 ports, where two of them are Gigabit ports and the other one is a 2.5G port. Apart from that, you would find 4 x USB 3.2 Gen 1 Type-A ports, 3 x USB 3.2 Gen 2 Type-A port, 1 x USB 3.2 Gen 2 Type-C port, 2 x antenna outputs for WiFi, 1 x PS/2 port, 1 x HDMI port, 1 x DP port, 6 x audio jacks, and a Clear CMOS button. The motherboard uses the renowned Realtek ALC1220 Audio Codec and also supports Creative Sound Blaster Cinema 5. One of the best things about the Asrock motherboards is that they come with supreme-quality VRMs and that is quite necessary for high overclocking. Since Intel Core i9-9900K is a power-hungry processor, this motherboard takes care of all that requirement nicely and allows 5.0 GHz+ clocks using IR Digital PWM 12 phase VRM, as long as your chip is not one of the bad ones. Also, the cooling of the processor greatly affects the overclocking. The memory support of the motherboard is noticeably superior to other Z390 motherboards, providing up to 4266 MHz memory clocks with overclocking, although it will be quite expensive to buy sticks that would support such clocks. 

The Good

  • Lots of storage options
  • Comes with three LAN ports and WiFi as well
  • Overclocking capabilities are beyond imagination

The Bad

  • One of those expensive enthusiast-grade motherboards

Asus ROG Maximus XI Gene Z390

Asus ROG Maximus XI Gene Z390
Asus ROG Maximus XI Gene Z390

Brand: ASUS | Chipset: Intel Z390 | Socket: LGA 1151 | Form Factor: Micro ATX | Memory: 32 GB DDR4 | Memory Speed: 2133 MHz

ASUS ROG MAXIMUS XI GENE is a top-quality motherboard that has won several awards from enthusiasts, making it one of the best Micro ATX motherboards that you can couple with Intel Core i9-9900K. You get high-quality VRM, fast memory support, incredibly rich audio quality, and an additional DIMM.2 card while you will have to compromise on the number of DIMM and PCI-E slots. ASUS ROG MAXIMUS XI GENE is based on the Z390 chip, which is although not the latest chipset for Intel Core i9-9900K but it is surely one of the best Micro-ATX motherboards that you can use in combination with the Intel Core i9-9900K. First of all, the design of the motherboard is similar to other ROG MAXIMUS series motherboards. There is an RGB-lit ROG logo on the I/O cover while there is ROG GENE written on the M.2 heat-sink, which is also RGB-lit. It is a pretty small motherboard comparing to regular ATX motherboards that come with those additional PCI-E slots.

There are only two DIMM slots on the motherboard and right next to the DIMM slots, you can find the slot for the DIMM.2 module that provides extra storage capacity in combination with M.2 storage disks. Since there are only two DIMM slots, you can use a maximum memory of 64 GB, although that is more than what most users would have thought of. Moreover, two DIMM slots allow higher memory clock rates and that is why this motherboard supports up to 4800 MHz of memory clocks with overclocking which is astonishing.  ASUS ROG MAXIMUS XI GENE has single PCI-E slot on the motherboard, which is an X16 slot as expected while there are four SATA III ports and two M.2 slots.

The I/O of the motherboard is quite extensive and provides 6 x audio ports, 3 x USB 3.2 Gen 2 Type-A ports, 4 x USB 3.2 Gen 1 Type-A ports, a BIOS button, a Clear CMOS button, a PS/2 port, an HDMI port, an RJ45 port, and two antenna outputs. As the antenna outputs indicate, the motherboard does support WiFi and also Bluetooth 5.0. The motherboard uses ROG SupremeFX8-Channel High Definition Audio CODEC S1220A, which is one of the best audio Codec by Realtek being enhanced by ASUS. You also get Sonic Studio III support along with Sonic Studio Link. Now, coming to the VRM of the motherboard, you can see that the motherboard uses a 12-phase VRM accompanied by large heat-sinks. You shouldn’t be having any problem overclocking a 9900K to past 5 GHz as long as the cooling capabilities are fine. As for the PSU connectors, the motherboard does provide an additional 8-pin power connector if you want to give extra juice to the motherboard.

The Good

  • DIMM.2 card feels novel
  • Super-fast memory clock rates

The Bad

  • Limited DIMM and PCI-E slots
