Bringing PCIe Gen 4.0 support to Intel

MSI MEG Z590 ACE is the latest member of the ACE lineup of flagship motherboards from MSI and it’s built to make the most of the Intel Z590 platform for their latest 11th Gen Intel Core “Rocket Lake” desktop processors. The MEG Z590 ACE is right at the top alongside the MSI MEG Z590 GODLIKE and the MPG Z590 CARBON EK X. We haven’t spotted the MSI MEG Z590 ACE selling in India yet so we can’t comment on the Indian price but a peek at Newegg shows the board listed for USD 587 which works out to a little over INR 50K with 18% GST added to the direct forex conversion. The actual price could very well end up a little higher. Comparing this to the launch price of the MSI MEG Z490 ACE tells us that it’s a bit more expensive but then again we get PCIe Gen 4.0 on the Z590 boards (provided they’re paired with an 11th Gen CPU) and that does add up a little. Let’s take a closer look at the MEG Z590 ACE.

We see the same colour scheme on the MEG Z590 ACE as we did on the MSI MEG Z490 ACE. The same black and gold aesthetic with a slightly different style language is used here. The packaging holds no punches in screaming out about PCIe Gen 4.0. The RGB elements have been toned down comparatively. We have a new RGB dragon logo on the rear I/O shroud and another one tacked onto the PCH heatsink. That being said, all the connectors for the different RGB ecosystems are all present so no matter which RGB ecosystem you go with, you should be able to make it work without any trouble. There’s a bit more metal on the board in the form of additional M.2 heatsinks and that gives the board a more unibody look.

Package contents

Like all flagship motherboards, the MSI MEG Z590 ACE comes with plenty of accessories and essential cables in the box. We see a couple of new additions over the older gen Z490 board. Aside from the usual user manual, quick start guide and SATA cables and stickers, we see a cleaning brush, pair of Philips and flathead screwdrivers, DP to mini-DP cable, RGB extension cables, and cables for RAINBOW and Corsair RGB connectors.

The pair of screwdrivers and cleaning brush is an odd but welcome addition to the accessory bunch. We certainly had a lot of use for the screwdrivers right out of the box. Given the mesh design and the textured surfaces used across the board, we’re certain that the brush is going to come handy as well.

Board Layout

The MSI MEG Z590 ACE is packed to the hilt with features and has a very busy layout. Thankfully, the massive heatsinks spread across the length and breadth of the motherboard manage to hide it all and give it a cleaner look. Let’s take a close look at the components. 

CPU Area and VRM

The CPU area is quite packed from all sides but the screw mounting holes have plenty of clearance. VRM heatsinks on the top and sides aren’t ridiculously tall. You should have no trouble installing most CPU coolers on this board. Low-profile coolers would be a little difficult to install. The VRM heatsinks are massive metal chunks with a single heat pipe running through them. The board uses two 8-PIN EPS connectors which are situated on the top-left and we had no problems while plugging or unplugging the power connectors after the board was mounted into a chassis.

After taking the heatsinks off the board we get to take a gander at the VRM. The MSI MEG Z590 ACE uses the same Intersil ISL69269 controller as the Z490 ACE. For the power stages, it uses 16 Intersil ISL99390 90 Amp MOSFETs and for the SOC, it uses two Renesas RAA220075 75 Amp MOSFETs. MSI states that they’ve gone with a 16+2+1 power phase design on this motherboard. The Intersil ISL69269 controller can only handle up to 12 phases, so MSI is using doublers here to get the 16 phases for the Vcore and while the two phases for the SOC are not using any doublers. These doublers used are Renesas ISL617A and they can be seen on the rear of the board underneath the aluminium backplate.

At the end of the day, the Vcore can use up to 1440 Amperes via this setup so you’ve got a pretty capable VRM set up here. 

RAM Slots

There’s a decent amount of clearance between the CPU socket and the RAM slots. Speaking of which, MSI is using slots with latches on just one side. This is a bit convenient to install modules into, especially when you consider the fact that the bottom-end of the RAM slots tend to be situated a little too close to the graphics card. So unlatching the bottom-end becomes difficult. In this case, you’re not going to face that issue. The RAM slots themselves have metal shields to add some rigidity.

Around the top of the RAM slots, we have two PWM fan headers, the RGB connectors and the debug code LED indicator. On the right of the RAM slots, you see a few test pads and the boot-up status LEDs right next to the main 24-pin ATX power connector.

Expansion slots

The MSI MEG Z590 ACE has 3 x16 PCIe slots, 2 x1 PCIe slots and 4 NVMe slots. The first two of the x16 PCIe slots are from the CPU and the third one comes from the PCH. The ones coming from the CPU support PCIe Gen 4.0 when a 11th Gen CPU is installed and the third x16 PCIe slot comes from the chipset so you only get PCIe Gen 3.0 on that. These slots can be configured in either a 16/0/4 arrangement or in an 8/8/4 arrangement. The two x1 PCIe slots come from the PCH. Talking about multi-GPU configurations, you can have a 3-way CrossFire or 2-way SLI. Although multi-GPU configurations are being phased out by manufacturers so unless you’re using GPUs for GPGPU compute, these are worthless.

MSI MEG Z590 ACE Gaming Motherboard PCIe M.2 Expansion slots for Intel 11th Gen

With all the heatsinks removed, we see there are four 110mm M.2 slots on the MEG Z590 ACE. The first one is capable of PCIe Gen 4.0 when an 11th Gen CPU is installed while the remaining three only support PCIe Gen 3.0. The second and third M.2 slots from the top also support SATA drives and share bandwidth with the SATA ports on the right. The Z490 chipset supports RAID 0, 1, and 10 for SATA and RAID 0 and 1 for M.2. There is no option for RAID 5 since that requires a minimum of three drives to be connected via the same protocol. The MSI MEG Z590 ACE makes use of ASMedia ASM1480 mux/demux for handling the PCIe lanes between all the connectors.


Onboard Connectors

The MSI MEG Z590 ACE has a decent set of onboard connectors. We counted 6x PWM fan connectors along with 1x 4-pin CPU fan connector and 1x high-amp 4-pin water pump connector for AIOs.

The physical LED switch right next to the power switch is a nice addition for folks who don’t want to dig through the BIOS to disable all the LEDs.


Usually, the audio CODEC doesn’t change for a couple of years with just minor improvements being visible across several generations of motherboards. That is not the case here since the MSI MEG Z590 ACE comes with the latest Realtek ALC4082 audio CODEC. It’s aided by the ESS SABRE 9018 Q2C audio DAC that was introduced six years ago. At least some things have changed.

Like most flagship boards, the audio circuitry on the MEG Z590 ACE is shown to have a physical separation to reduce interference. We don’t see any shielding used on the CODEC or the DAC. 

Rear I/O

There’s no active cooling elements within the rear I/O shroud this time so we…
