MSI Z370I Gaming Pro Carbon AC Visual Inspection

We know being a Mini-ITX sized board there really isn't a lot of room to doll up the motherboard and make it look pretty. But many who are using this size motherboard are using it in a small case and perhaps tucked away. That isn't to say they need to be hidden away but room for creativity is trumped by the need to add more functionality. The Z370I Gaming Pro Carbon AC packs a lot of features on it including a single M.2 slot, four SATA ports, and the latest Realtek audio among other things.

There are no designs on the board, though we are able to see the traces running around the socket providing a cool if mechanical type aesthetic to the black PCB. Cooling the power delivery area(s) are two heat sinks that have what look to be a carbon fiber-like pattern on them. The PCH heatsink below the socket contains the MSI name as well as the same carbon fiber like patterns. Both the DRAM slots and PCIe slot are reinforced giving additional support for the items installed. The Gaming Pro Carbon AC has its share of RGB LEDs, eight to be exact, running the length of the right side of board on the underside which gives it a nice glow when powered on.

The board includes two fan headers to support cooling needs. Both headers are hybrid and offer users control via PWM and voltage. The manual does not note if the headers are high-output so assume a typical 1A/12W capabilities. The fans are controlled through the BIOS as well as through Windows via the Command Center software.

Typically, the back of the board is shown to show the electrical connections of multiple PCIe slots. In the case of Mini-ITX boards, there is only one and it is, as expected, wired as an x16 slot. The real reason for this image is to show the location of the M.2 slot on the board which is just above the solder points of the PCIe slot and below the socket backing. This location frees up a bit of space on the front and allows for up to a 2280 size M.2 module to fit in the provided space.

Power delivery on the Z370I Gaming Pro Carbon AC is a total of eight phases in a 6+2 configuration (CPU and iGPU). Managing this power is a uBIQ Semiconductor uP9508Q multi-phase controller listed as 3/2/1+2 controller. Handling the phase doubling duties are uP1061S phase doublers located on the back behind the VRMs. The board uses uBIQ Semiconductor QM3816 MOSFETs which should be able to handle our i7-8700K with little fanfare.

The right side of the tiny motherboard has a lot going on including two DRAM slots capable of supporting DDR4-4600 Memory in its reinforced slots. We are also able to see the four SATA ports flanking the memory slots. Other more easily visible connectors include a front USB 2.0 port on the left, the System fan and front panel headers in the middle, along with the 24-pin ATX 12V connector on the right. Sitting just above the bottom two SATA ports is MSI's debug LEDs which light up during boot time and stay lit if there is an issue. The four LEDs cover issues with Boot, VGA, DRAM, and the CPU. Since there isn't any room for a 2-digit LED, this is a welcome addition for troubleshooting boot issues.

Above we are able to see a closer shot of the four SATA ports. All four ports will be available even when the M.2 slot is populated with a PCIe NVMe or SATA based M.2 module since there are enough PCIe lanes available from the PCH.

The board's back panel IO is pretty well populated with ports and buttons, with about every port that that is found on a full-size board including dual video outputs, USB ports (2.0-3.1), LAN, keyboard/mouse, and audio. Peeking out behind the audio stack we are able to see the Chemi-Con capacitors used with the Realtek ALC1220 codecs for sound.

    I would like to know how many people actually have multiple m.2 drives. I typically just install a single drive and if I need additional storage, fallback to SATA.

    I might have to pick up one of these and a Node 202 case or something for a small, compact gaming PC.

    I bought the ASRock AB350M Pro4 specifically because it had two M.2 slots. (One supporting both PCIe and S-ATA and the other one only S-ATA.) This allows for one very fast system and application drive and one bigger and cheaper as video editing scratch disk. This keeps the number of cables lower. Airflow can probably be debated because on one hand M.2 drives may not get much air, but on the other hand S-ATA PCBs are enclosed and don't get much airflow either.
    Price-wise M.2 S-ATA drives are almost the same as 2.5" S-ATA drives. I wouldn't be surprised if M.2 got cheaper than S-ATA over time due to the size of the enclosure and packaging, but it's more likely mostly due to supply and demand.

    In case of Node 202, the other m.2 slot would come in handy for expansion. I have the Asus z370i strix in it, and with a large gpu and non-modular psu, the hdd bracket would be a nuisance, and I am unsure if it would even fit. With storage-oriented (as compared to performance-oriented) nvme drives coming down in price, I would consider buying another nvme drive for expanded storage rather than a 2.5 inch ssd. At least in case of Node 202, that is.

    m.2 drives have come down in price especially if you're going for a SATA m.2. Much more elegant, no cable clutter, and generally faster for a small price premium
  • DanNeely - Thursday, August 23, 2018 - link

    For people going with even smaller new SFF cases than you're co, there might not even be an HDD bay at all making it m.2 or MacGyver for solid state drives.

    i have 3 x 1TB drives. in my TR system.
  • Dug - Sunday, August 26, 2018 - link

    I use 2 m.2 drives and wish I could use three, but there would be a performance hit for doing so.
    1 for OS and all apps. 2nd for games and editing files. Sata drive for back up and photos.

    I currently use 3 M.2 cards (2x PCIe M.2 & 1x Sata M.2) on the MSI Z370 Gaming Pro Carbon. Got 1 PCIe M.2 in the top slot, the sata M.2 in the bottom, and an older PCIe M.2 in a M.2 PCIe x4 add-in adapter card (Akasa AK-PCCM2P-01). The latter is in the bottom PCIe x8 slot.
    The plan is to buy a 1TB PCIe M.2 that will go in the bottom M.2 slot and move the sata M.2 in the Akasa adapter. The card currently in the adapter is not enough for my games but will work just fine in a htpc.

    One query: is it possible to connect multiple headphones using the back audio jacks? ( Without using any splitter or external DAC, just those 3.5mm ports)
    I just need stereo audio through each headphones, nothing fancy...
  • DanNeely - Thursday, August 23, 2018 - link

    AFAIK no boards support this unless you've got a pair that can connect over the optical port (do these exist?). The various analog pins are to support separate location channels for surround sound, so if you plug in multiple headphones the audio controller will think you've got front, and center, or side, or etc speakers.
