MSI MEG Z590 Ace Review: New Ace in Town

(Image credit: MSI)

While we still don’t have an Intel Rocket Lake-S Core i9-11900K CPU to use for testing, Intel Z590 boards have been rolling in. So while we await benchmark results, we’ll be walking in detail through the features of these brand-new boards. First up on our bench was the ASRock Z590 Steel Legend 6E Wi-Fi, followed by the Gigabyte Z590 Aorus Master and Gigabyte’s Z590 Vision G. Today, we take a close look at the MSI MEG Z590 Ace. We’ll have to wait for benchmark results, though, to see if it deserves a spot on our best motherboards list.

The latest version of the Ace board features robust power delivery, four M.2 sockets, a premium audio codec and more. The new Ace also has updated styling on the heatsink and shrouds while still keeping the black with gold highlights theme from the previous generation. Emblazoned on the rear IO is the MSI Dragon (with RGB LEDs) and the Ace name (no lighting). We don’t have an exact price for the MEG Z590 Ace. However, the Z490’s MSRP was $399, so we expect the Z590 version to cost the same or slightly more.

MSI’s current Z590 product stack consists of 11 models, with most falling into the MEG (high-end) MPG (mid-range) and MAG (budget) lineups. We’re greeted by several familiar SKUs and a couple of new ones.  Starting at the top is the flagship MEG Z590 Godlike, the Ace we’re looking at now, and a Mini ITX MEG Z590I Unify. The mid-range MPG line consists of four boards (Carbon EK X, Gaming Edge WiFi, Gaming Carbon WiFi and Gaming Force), while the less expensive MAG lineup consists of two boards (Z590 Tomahawk WiFi, and Torpedo). Wrapping up the current product stack are two ‘Pro’ boards in the Z590 Pro WiFi and Z590-A Pro. The only thing missing out of the gate is a Micro ATX board, but it’s likely we see one or two down the line.

We can’t talk about Rocket Lake-S performance yet — not that we have a CPU at this time to test boards with anyway.  All we’ve seen at this point are rumors and a claim from Intel of a significant increase to IPC. But the core count was lowered from 10 cores/20 threads in Comet Lake (i9-10900K) to 8 cores/16 threads in the yet-to-be-released i9-11900K. To that end, we’ll stick with specifications and features, adding a full review that includes benchmarking, overclocking and power consumption shortly.

MSI’s MEG Z590 Ace includes all the bits you expect from a premium motherboard. The board has a stylish appearance, very capable power delivery (16-phase 90A Vcore) and the flagship Realtek ALC4082 audio codec with included DAC. We’ll cover these features and much more in detail below. First, here are the full specs from MSI.

Looking at the Z590 Ace for the first time, we see the black PCB along with black heatsinks and shrouds covering most of the board. MSI stenciled on identifying language such as the MEG Ace name and the MSI Gaming Dragon in gold, setting this SKU apart from the rest. The VRM heatsinks are both made from a solid block of aluminum with lines cut out. Additionally, the shroud is made of metal and connected to the heat pipes, increasing surface area significantly. Also worth noting is the VRM heatsinks share the load connected via heatpipe. RGB LED lighting is minimal here, with a symbol on the chipset shining through a mesh cover on the chipset heatsink and the MSI dragon above the rear IO. While tastefully done, some may want more. With its mostly black appearance, the board won’t have trouble fitting in most build themes.

Focusing on the top half of the board, we’ll get a better look at what’s going with the VRM heatsinks and other board features in this area. In the upper-left corner, we spot two 8-pin EPS connectors, one of which is required for operation. Just below this is the shroud covering the rear IO bits and part of the VRM heatsink. On it is a carbon-fiber pattern along with the MSI Gaming Dragon illuminated by RGB LEDs. The socket area is relatively clean, with only a few caps visible.

Just above the VRM heatsink is the first of eight fan headers. All fan headers on the board are the 4-pin type and support PWM- and DC-controlled fans and pumps. The CPU_FAN1 header supports up to 2A/24W and auto-detects the attached device type. The PUMP_FAN1 supports up to 3A/36W. The rest of the system fan headers support up to 1A/12W. This configuration offers plenty of support for most cooling systems. That said, I would like to have seen all pump headers auto-detect PWM/DC modes instead of only CPU_FAN1.

To the right of the socket are four reinforced DRAM slots. The Z590 Ace supports up to 128GB of RAM with speeds listed up to DDR4 5600 (for one stick with one rank). The highest supported speed with two DIMMs is DDR4 4400+, which is plenty fast enough for an overwhelming majority of users.

MOving down the right edge of the board, we see the 2-character debug LED up top, a system fan header, five voltage read points (Vcore/DRAM/SA/IO/IO2), 4-LED debug, 24-pin ATX connector, and finally, a USB 3.2 Gen2 Type-C front panel header. Between both debug tools and the voltage read points, you’ll have an accurate idea of what’s going on with your PC.

With the MEG Z590 Ace towards the top of the product stack, you’d expect well-built power delivery and you wouldn’t be wrong. MSI lists the board as 16+2+1 (Vcore/GT/SA) and it uses a Renesas ISL69269 (X+Y+Z = 8+2+1) PWM controller that feeds power to eight-phase doublers (Renesas ISL617A), then onto 16 90A Renesas ISL99390B MOSFETs for the Vcore. This configuration yields 1440A of power for the CPU, which is plenty for ambient and sub-ambient/extreme overclocking. It won’t be this board holding you back in any overclocking adventures, that’s for sure.

As we focus on the bottom half, we’ll take a closer look at the integrated audio, PCIe slot configuration and storage. Starting with the audio bits on the left side, under the shroud, is the Realtek latest premium codec, the ALC4082. Additionally, the Z590 Ace includes an ESS Sabre 9018Q2C combo DAC, a dedicated headphone amplifier (up to 600 Ohm) and high-quality Chemicon audio capacitors. This audio solution should be more than adequate for most users.

In the middle of the board are four M.2 sockets and five PCIe slots. With the PCIe connectivity, all three full-length slots are reinforced to prevent shearing and EMI, while the two PCIe x1 slots don’t have any reinforcement. The top slot supports PCIe 4.0 x16 speeds, with the second and third slots PCIe 3.0. The slots break down as follows, x16/x0/x4 x8/x8/x4 or x8/x4+x4/x4. This configuration supports 2-Way Nvidia SLI and 2-Way AMD Crossfire technologies. All x1 slots and the full-length bottom slot are fed from the chipset, while the top two full-length slots source their lanes from the CPU.

M.2 storage on the Z590 Ace consists of four onboard sockets supporting various speeds and module lengths. The top slot, M2_1, supports PCIe 4.0 x4 modules up to 110mm. Worth noting on this socket is that it only works with an 11th Gen Intel CPU installed. M2_2, M2_3, M2_4 are fed from the chipset, with M2_2 and M2_3 supporting SATA- and PCIe-based modules up to 80mm, while M2_4 supports PCIe only. M2_2/3/4 are all PCIe 3.0 x4.

The way this is wired, you will lose some SATA ports and PCIe bandwidth depending on the configuration. For example, SATA2 is unavailable when using a SATA-based SSD in the M2_2 socket. SATA 5/6 are unavailable when using the M2_3 socket with any type of device. Finally, the bandwidth on M2_4 switches from x4 to x2 when PCI_E5 (bottom x1 slot) is used. The M.2 sockets support RAID 0/1 for those who would like additional speed or redundancy.

Finally, along the right edge of the board are six horizontally oriented SATA ports. The Z590 Ace supports RAID 0, 1 and 10 on the SATA ports. Just be aware you lose a couple of ports on this board if you’re using some of the M.2 sockets. Above these ports is a USB 3.2 Gen1 front panel header along with another 4-pin system fan header.

Across the board’s bottom edge are several headers, including more USB ports, fan headers, and more. Below is the full list, from left to right:

  • Front Panel Audio
  • aRGB and RGB headers
  • (3) System Fan headers
  • Supplemental PCIe power
  • Tuning controller connector
  • Temperature sensor
  • (2) USB 2.0 headers
  • LED switch
  • BIOS selector switch
  • OC Retry jumper
  • TPM header
  • Power and Reset buttons
  • Slow mode jumpers
  • Front panel connectors

Moving to the rear IO area, we see the integrated IO plate sporting a black background with gold writing matching the board theme. There are eight USB Type-A ports (two USB 3.2 Gen2, four USB 3.2 Gen1 and two USB 2.0 ports). On the Type-C front, the Z590 Ace includes two Thunderbolt 4 ports capable of speeds up to 40 Gbps. Just to the right of those are Mini-DisplayPort inputs for running video through the Thunderbolt connection(s). Handling the video output for the CPU’s integrated graphics is a single HDMI (2.0b) port. We also spy here the Wi-Fi antenna connections, 5-plug plus SPDIF audio stack, Intel 2.5 GbE and finally, a Clear CMOS button and BIOS Flashback button that can be used without a CPU.

Software

For Z590, MSI has changed up its software offerings. We used to have several individual programs to adjust the system, but MSI moved to an all-in-one application called MSI Center with thisboard. The new Software is a central repository for many of the utilities (12) MSI offers. These include Mystic Light (RGB control), AI Cooling (adjust fan speeds), LAN Manager (control the NIC), Speed Up (for storage), Gaming Mode (auto-tune games), among several others (see the screenshots below for details). The User Scenario application has a couple of presets for system performance and is where you manually adjust settings, including CPU clock speeds and voltage, RAM timings, and more. Overall, I like the move to a single application. The user interface is easy to read and get around in. However, sometimes loading these applications takes longer than I would like to see. But MSI Center does an excellent job of pulling everything in.

Firmware

To give you a taste of the Firmware, we’ve gathered screenshots showing most BIOS screens. MSI’s BIOS is unique from the other board partners in that the headings aren’t at the top but split out to the sides. In each section, all the frequently used options are easy to find and not buried deep within menus. Overall, MSI didn’t change much here when moving from Z490 to Z590 and their BIOS continues to be easy to use.

Future Tests and Final Thoughts

With Z590 boards arriving but now Rocket Lake-S CPUs yet, we’re in an odd place. We know most of these boards should perform similarly to our previous Z490 motherboard reviews. And while there are exceptions, they are likely mostly at the bottom of the product stack. To that end, we’re posting these as detailed previews until we get data using a Rocket Lake processor.

Once we receive a Rocket Lake CPU and as soon as any embargos have expired, we’ll fill in the data points, including the benchmarking/performance results, as well as overclocking/power and VRM temperatures.

We’ll also be updating our test system hardware to include a PCIe 4.0 video card and storage. This way, we can utilize the platform to its fullest using the fastest protocols supported. We will also update to the latest Windows 10 64-bit OS (20H2) with all threat mitigations applied and update the video card driver and use the newest release when we start this testing. We use the latest non-beta motherboard BIOS available to the public unless otherwise noted. While we do not have performance results from the yet-to-be-released Rocket Lake CPU, we’re confident the 70A VRMs will handle the i9-11900K processor without issue. A quick test of the i9-10900K found the board quite capable with that CPU, easily allowing the 5.2 GHz overclock we set. For now, we’ll focus on features, price, and appearance until we gather performance data from the new CPU.

The MSI MEG Z590 Ace is a premium motherboard adorned with several high-end features, including a very robust VRM capable of handling 10th and 11th generation flagship Intel processors at both stock speeds and overclocked. Additionally, the board includes four M.2 sockets, 2.5 GbE and integrated Wi-Fi 6E, and two Thunderbolt 4 ports for increased bandwidth and peripheral flexibility.

The MEG Z590 Ace’s 16-phase 90A VRM handled our i9-10900K without issue, even overclocked to 5.2 GHz. We’ll retest once we receive our Rocket Lake-based i9-11900K, but so long as the BIOS is right, it shouldn’t pose any problems for this board. Although it has four M.2 sockets, unlike the Gigabyte Z590 Vision G, using these sockets causes SATA ports to drop, because more lanes are tied to the chipset on this board). That said, if you’re in a worst-case scenario, you can run four M.2 modules and still have three SATA ports left over. Most users should find this acceptable.

As far as potential drawbacks go, the price point of $400-plus will be out of reach for some users. Another concern for some may be the lack of RGB elements on the board. The MSI dragon and chipset heatsink light up with RGB LEDs, but that’s it. If you like a lot of RGB LED bling, you can add it via the four aRBG/RGB headers located around the board. The other drawback is the lack of a USB 3.2 Gen2x2 Type-C port, but the faster Thunderbolt 4 ports certainly make up for that.

Direct competitors at this price point are the Asus ROG Strix Z590-E Gaming, Gigabyte Z590 Aorus Master, and the ASRock Z590 Taichi. All of these boards are plenty capable with the differences residing in VRMs (Gigabyte gets the nod here), M.2 storage (MSI and Giga both have four) and audio (the Ace has the most premium codec). Beauty is in the eye of the beholder, but if you forced me to pick among these, the Taichi would be the board I’d want to show off the most. That said, no board here is a turnoff and has its own benefit over another.

The Ace’s appearance, including the brushed aluminum and carbon fiber-like finish, really gives it a premium look and feel, while easily blending in with your build theme. If your budget allows for a ~$400 motherboard and you’re looking for a lot of M.2 storage and enjoy a premium audio experience, the MEG Z590 Ace is an excellent option near that price point. Stay tuned for benchmarking, overclocking, and power results using the new Rocket Lake CPU.
