It’s clear that the Z390 Aorus Xtreme is targeted towards gamers and enthusiasts looking to harness the best quality and best performance of the Intel 9th generation Core i7-9700K and i9-9900K processors.

The GIGABYTE Z390 Aorus Xtreme looks to have the tools capable of overclocking with an advertised 12-phase power delivery and has its own OC button and header located at the top corner of the PCB.

With a Thunderbolt 3 GPIO header onboard, the Z390 Aorus Xtreme is one of only a select few to have one and that adds to the overall uniqueness; it’s hard in a large segment to stand out from the crowd, which the Z390 Aorus Xtreme is looking to do.

Design wise the Z390 Aorus Xtreme looks rather familiar and resembles the previous Z370 Gaming 7 which this model directly replaces. The most notable aspect is the steel PCB brace on the rear of the board which is also present on its much more expensive Z390 Aorus Master boards.

The GIGABYTE Z390 Aorus Xtreme also has a full rear IO cover which extends across the power delivery with an L shaped heat sink. The Gigabyte Z390 Aorus Xtreme competes with the MSI Z390 Gaming Pro Carbon AC and the Asus ROG Maximus XI Hero (Wi-Fi), with a better price and features.

It has two M.2 slots, Intel Wi-Fi Wave2 and Ethernet, a full RGB treatment with multiple headers, and ALC1220 audio. You’d have climb to the top of the merchandise stack to urge an equivalent from MSI and ASUS, both of whom offer more polish but also charge plenty for the privilege.

This is often great value. In our test suite, the GIGABYTE Z390 Aorus Xtreme showed good system performance overall with some very efficient power consumption numbers in idle and load states.

The time in our POST time testing also proved fruitful, but the DPC latency performance out of the box gave one of the highest latencies from an LGA 1151 board we have tested so far. In our general testing, the Z390 Aorus Xtreme is competitive, but we unfortunately experienced an anomaly in our game testing with slightly off the mark performance than was expected.

During the overclock testing on the Z390 Aorus Xtreme, we had to take a slightly different approach due to some instability as we went through the multipliers with default power settings. To do the testing we had to make a wave of changes in the firmware which isn’t out of the ordinary and would be beneficial, but it should be noted that it’s the first time I’ve had to do this in a mainboard review.

It should also be noted that while using the AutoTuning profile which lets the firmware determine which overclock is stable after a test cycle of between 10 and 15 minutes, wasn’t stable and crashed instantly. And this motherboard is for i9 9900k also.

ASUS ROG MAXIMUS XI HERO WiFi Z390

The Asus ROG Maximus XI Hero (Wi-Fi AC) is that the latest during a long line of popular boards. While Asus offers the Code, Formula, and Apex boards a step above the Hero, we found a little reason to travel with the pricier models.

The minor bumps in speed, features, or fashion that costlier boards offer area unit tough to justify. This is often a minor update to the previous Maximus X Hero Wi-Fi, which we also liked.

This year’s Hero adds 802.11ac 2×2 MU-MIMO Wi-Fi to the networking mix (a non-wireless version is out there for a couple of bucks less). Overclocking and performance remain first in class, united with boards costing a third more. 

The board is nearly perfect with better Wi-Fi and an extra M.2 slot on our shortlist of potential improvements. And this is the 4th best motherboards for i9 9900K for making your best PC.

It’s clear that the ASUS ROG MAXIMUS XI HERO Wi-Fi Z390 is targeted towards gamers and enthusiasts looking to harness the best quality and best performance of the Intel 9th generation Core i7-9700K and i9-9900K processors.

The ASUS ROG MAXIMUS XI HERO Wi-Fi Z390 looks to have the tools capable of overclocking with advertised 12-phase power delivery and has its own OC button and header located at the top corner of the PCB.

With a Thunderbolt 3 GPIO header onboard, the ASUS ROG MAXIMUS XI HERO Wi-Fi Z390 is one of only a select few to have one, and that adds to the overall uniqueness; it’s hard in a large segment to stand out from the crowd, which the ASUS ROG MAXIMUS XI HERO Wi-Fi Z390 is looking to do.

The Asus ROG Maximus XI Hero Wi-Fi comes with a Z390 chipset, which means it’s primed to handle Intel’s 8th and 9th gen cores. Its redesigned 5-way optimization overclock supported thermal telemetry.

It also has 802.11ac 2×2 MU-MIMO Wi-Fi so, you won’t have to buy a separate card. There are plenty of USB slots and, of course, its RGB lighting works with a bunch of (Aura Sync) compatible peripherals. The only thing missing is a third M.2 slot.

More than anything in an extreme gaming PC, the graphics cards or cards matter. In sticking with our ‘not entirely insane’ mantra, we’ve elected to go with one RTX 2080 Ti rather two, because the one will get the job done. If you really want two RTX 2080 Tis, you’ll need an NVLink bridge, and the only thing to worry about here is whether the games you play support SLI.

Motherboard: I know for a fact that I went a little overboard when I bought this motherboard, but boy does it look great! The performance of a ASUS ROG motherboard is truly amazing; they’re one of a kind. This motherboard also came with an 802.11ac Wi-Fi adapter and a Bluetooth 4.0 connectivity, so I really believe I got my money’s worth.

This motherboard is for i9 9900k also, But one of the main reasons, I got this board was because it had the ROG Armor feature similar to the ASUS Sabertooth boards. You probably can tell that I’m an ASUS fan.

GIGABYTE Z390 AORUS PRO WiFi best motherboards for i9 9900K

The GIGABYTE Z390 Aorus Pro WiFi is a full size ATX motherboard and is advertised to have a large 12-phase power delivery.

The board has a trio of PCIe 3.0 full-length slots with the top two slots operating at x16/x0 and x8/x8 from the CPU and the third slot wired directly to the Z390 chipset which runs at x4; all three full-length slots feature metal slot reinforcement and offers support for three-way CrossFire and two-way SLI multi-graphics configurations. And this is the 3rd best motherboards for i9 9900K for making your best PC.

For something as powerful as the GTX 1080 Ti motherboard, you definitely want something that can support its power and heat output. That said, the GIGABYTE Z390 AORUS PRO WiFi motherboard will be right up your alley.

This one handles video card overclocking just fine, and there’s plenty of connections and slots for other things, such as four DDR4 RAM memory slots. The mainstream motherboard market remains predominantly focused on gamers and gaming features.

From the useful to the inane, saying a device is ‘gaming’ is clearly bringing in the sales, and it becomes an all out marketing war.Each company is clearly trying to build a gaming brand beyond the company name, even if it means always being confused at how to pronounce it (Ay-orus, or Or-us?).

Nonetheless, it is clear that each motherboard company is piling on the R&D dollars, as well as the design dollars, to ensure that it can convince users to part with some hard earned money in their next build. The GIGABYTE Z390 AORUS PRO WiFi even supports GIGABYTE’s two M.2 Support technology that dissipates heat from the board before it causes problems.

There are even nine temperature sensors spread across the Z390 AORUS PRO WiFi to sense cooling issues and keep you running at peak performance no matter how hard your session is perfect for zealous overclockers. And this motherboard is for i9 9900k also.

In our test suite, the GIGABYTE Z390 AORUS PRO WiFi showed good system performance overall with some very efficient power consumption numbers in idle and load states. The time in our POST time testing also proved fruitful, but the DPC latency performance out of the box gave one of the highest latencies from an LGA 1151 board we have tested so far.

In our general testing, the Z390 Aorus Xtreme is competitive, but we unfortunately experienced an anomaly in our game testing with slightly off the mark performance than was expected. Motherboards these days come with a plethora of temperature sensors and bundled software that allows you to control them.

Explore the BIOS options and dig through the junk that comes with your motherboard drivers to find these utilities. In my case, a GIGABYTE Z390 AORUS PRO WiFi, the utility is called SIV. SpeedFan is the holy grail of software defined fan control. It was arguably the most popular software during its time.

However, it looks like the author has abandoned the software and as a result it no longer supports newer motherboard chipsets. The tool does have a steep learning curve but the amount of features will justify it.

ASUS ROG STRIX Z390 E-GAMING ASUS ROG STRIX Z390 E-GAMING

The ASUS ROG Strix Z390-E Gaming amps the power delivery and stacks a comprehensive set of cooling options to tame Intel’s latest CPUs. As a Core i9-9900K overclocking board with the mid-level feature set, the ASUS ROG Strix Z390-E Gaming faces tough competition from pricier competitors that attempt to provide greater value in added features than the price difference.

Asus fills a number with that gap with improved RGB and a more-polished software interface. For performance-crazed gamers, its greatest accomplishment is that it overclocks as well as those pricier competitors. And this is the 5th best motherboards for i9 9900K for making your best PC.

With the price dropping and the previous Z390-based model starting to disappear from vendors, ASUS ROG STRIX Z390 E-GAMING moves into the top spot for the boutique ITX segment. Despite its diminutive size and paucity of upgrade options, the ASUS ROG STRIX Z390 E-GAMING provides excellent performance and value.

Boasting stable 5GHz overclocks using several memory speeds, including 3600MHz with tweaking, its single PCIe x16 slot pushed top-shelf graphics cards to speeds that matched or exceeded most Z370 ATX boards during testing. 

One might think that a mainstream product would be targeted towards average consumers, but there’s nothing average about the build-your-own crowd of PC enthusiasts. They get a range of boards that starts with low-end overclocking products and builds from there.

The middle mark regarding overclocking capabilities and features has been their mainstream, and that’s historically been priced around ⅔ of what a reasonably-equipped Core i9-9900K board will cost. Welcome the $240 (£220) mainstream gaming board, Asus ROG Strix Z390-E Gaming.

It should be no surprise that the ASUS ROG STRIX Z390 E-GAMING motherboard shows up on our list. This motherboard comes out of ASUS’ Republic of Gamers line of products, which makes the Strix a little pricier than most. And this motherboard is for i9 9900k also.

That’s because like anything in the ROG line the Strix was designed for sheer power. Pair it up with your GTX 1080 Ti, and you’ll get excellent performance in fact, you could fit two GTX 1080 Ti’s on this one if you wanted.

We’ve tested all these kits on a machine with an best Intel Core i9-9900K processor, ASUS ROG STRIX Z390 E-GAMING motherboard, and Nvidia GeForce GTX 1080 Ti graphics card.

This is a stupendously powerful PC that would normally run quad-channel memory; the specs of this machine means RAM will always be the bottleneck of performance, which is perfect for benchmarking.

GIGABYTE Z390 AORUS MASTER ASUS ROG STRIX Z390 E-GAMING

The GIGABYTE Z390 Aorus Master looks to offer one of the most comprehensive blends of features, aesthetics and highly competitive controller set in its price bracket.

If you’re considering a Z390 platform for your next build then chances are that you have already accepted the fact that it won’t be cheap and made the decision to chase the highest clock speed. Let’s have a glance at one among the most ‘premium’ Z390 motherboards available the ASUS Maximus XI Gene.

The Gene is that the MATX version of the ROG Maximus range and is out there again after being omitted from the line-up for a short time. All I can say is welcome back mate you’ve been missed.

So, what are we getting excited about here? The ASUS Maximus XI Gene is a Micro ATX (mATX) enthusiast motherboard built around the Intel Z390 chipset with four M.2, four SATA 6Gbps, support for DDR4 4800MHz and double capacity DIMM modules.

It additionally has gigabit local area network, 802.11ac Wi-Fi, ASUS’s ROG DIMM.2 dual M.2 enlargement card, USB 3.1 generation two and Aura sync RGB lighting controls.

The design and software take what is an impressive list of features to the next level so strap in and let’s take a closer look. If there was ever a motherboard with an identity crisis it’s this one.

Someone needs to remind the Maximus XI Gene that it’s a Micro ATX board because when it comes to features the Gene leaves most full-sized ATX Z390 motherboards in its dust.

The Maximus XI Gene is actually for enthusiasts or enthusiast gamers wanting a top-shelf gaming platform during a Micro ATX form factor where a full ATX board won’t fit. That makes the ROG Maximus XI Gene an excellent board for a really particular quite builder trying to find a compact, no-compromise PC.

Just know that it won’t be cheap, as this board currently sells for around $400 in the USA (UK gets it for only £300 inc. VAT). And you may not be able to carry over your double capacity RAM, as it’s based on an Asus derived spec that’s currently only supported by a few motherboards like this one. And this motherboard is for i9 9900k also.
