Visual Inspection

Setting its sights on professional and workstation users, the ASUS Pro WS X570-Ace encompasses a strict and elegant design without the plethora of RGB LEDs that plenty of other models do. Instead, the Pro WS X570-Ace uses straight angled black aluminium heatsinks with the fins aligned horizontally on an all-black PCB. This includes the power delivery heatsink, the actively cooled X570 chipset heatsink, and the single PCIe 4.0 x4 M.2 heatsink. Located around the edge of the board are six 4-pin headers which support one CPU fan, one AIO pump connector, and four chassis fans. At the bottom of the PCB is an ASUS NODE connector hardware interface controller. While there aren't many products out which support this, InWin is currently developing an OLED screen which can display statistics such as CPU temperature, and fan speeds.

In the top right-hand corner of the board is four memory slots with support for DDR4-4400 memory, and is capable of housing up to 128 GB of system memory. A lot of vendors mention support for ECC memory in its specifications, but the ASUS Pro WS X570-Ace has validated support for ECC memory (and non-ECC). This means users can build an X570 based workstation with all the benefits of ECC memory including options in the firmware for memory scrubbing and memory addressing; this ultimately comes down to processor support including the AMD Ryzen Pro models. The WS X570-Ace also benefits from ASUS's OptiMem which is essentially a method of making the memory trace layout more efficient and can help to reduce memory latencies when overclocking, as well as potentially increase memory frequency yield too.

The bottom full-length PCIe 4.0 slot on the Pro WS X570-Ace operates at x8

One of the main features that sets this model apart from the rest of the current X570 product stack is in its PCIe 4.0 support. The ASUS Pro WS X570-Ace has three full-length PCIe 4.0 slots which operate at x16, and x8/x8, and the bottom slot operates at x8 powered through the chipset. All three full-length slots include a coating of metal armor re-inforcement, and for users looking to use a dedicated soundcard or another networking card, ASUS also includes a single PCIe 4.0 x1 slot.

Although the ASUS Pro WS X570-Ace is more geared towards workstation users, its power delivery is more than suitable for enthusiasts looking to overclock Ryzen 3000 processors too. It has a 12+2 phase design that is controlled by an ASP1405I running at 6+1 which is a custom variation of an International Rectifier IR35201 PWM controller. ASUS has opted to use teaming as opposed to doubling up phases for better transient response across its X570 models. As a result of this, the CPU VCore section is running 12 x IR3555 60 A power stages and the SoC is using 2 x IR3555 60 A power stages which are teamed together in pairs to create the 6+1 design. Delivering power to the processor is a single 8-pin 12 V ATX CPU power input.

Moving onto the storage capabilities of the ASUS WS Pro X570-Ace, we have two PCIe 4.0 M.2 slots with the top M.2 slot allowing for both PCIe 4.0 x4 and SATA drives to be used which includes an M.2 heatsink. The M.2 slot located at the bottom of the board only has support for PCIe 4.0 x2 drives, although this model does include a U.2 PCIe 3.0 x4 slot, and four SATA ports with support for RAID 0, 1, and 10 arrays.

The ASUS Pro WS X570-Ace uses a Realtek ALC1200S HD audio codec which provides five 3.5 mm audio jacks, and an S/PDIF optical output. On the Realtek ALC1200S HD audio codec is an EMI shield and is supported with six gold Japanese audio capacitors. The audio PCB is also separated from the rest of the board's componentry.

On the rear panel are two Ethernet ports, one being Realtek RTL8117 and the other an Intel I211-AT. ASUS has included four USB 3.1 G2 Type-A, one USB 3.1 G2 Type-C, and two USB 3.1 G1 Type-A ports, as well as a pair of video outputs including an HDMI 1.4b, and DisplayPort 1.2. Touching on the Realtek RTL8117 Gigabit NIC, this is supported by the ASUS Control Center Express which is a server-focused application which also doubles up as a management controller. It allows for out-of-band management and hardware-level control.

What's in the Box

Included in the box is a very fundamental accessories bundle which includes four SATA cables, an M.2 screw package, a driver and software installation disc, an I/O shield, and a user manual. The most noteworthy accessory in the bundle is an ASUS VGA holder designed to eliminate sagging in heavyset graphics cards, which can not only damage the card but the PCIe slot too if it isn't secured properly.

    It's a stylistic choice. It's difficult (pointless) to debate the merits of someone's feelings about how something looks since that sort of thing boils down to opinion and taste. No matter which direction you go, those preferences are not rooted so much in attainment of functionality. Where the frustration begins is within a fairly large segment of the potential market for high end consumer and prosumer computing equipment has no desire to purchase gamer-styled products that typically feature RGB lighting. That segmet's demand is unsatisfied because manufacturers are not catering to them for various reasons and therefore there will be some that speak out in the small hope that a company will acknowledge the unmet demand and sell a suitable product. There's nothing childish about what's happening. You're just seeing economic forces and personal tastes at work.

    No thunderbolt 3, no 10GbE. That really holds it back from being a serious workstation board. I couldn’t use it.

    Then msi creation could be suitable to you. Very well done IO section in that board. It seems to miss the ecc memory though... but if all that is needed the upcoming threatripper solutions could ansver that too!

    I agree. When looking for a new system board, this wouldn't do.
    I checked their site and there is no mention of thunderbolt support anywhere.

    I agree. And the second M.2 at only x2 is disappointing, as that basically ruins it for RAID 0/1.

    I like AMD for PCIe 4.0, but I want I/O, not x3 GPU, so I was looking at the Gigabyte X570 Aorus Xtreme, which has x16/x8/x4, ECC, 10GbE (Aquantia boo), triple x4 m.2, and 6 SATA ports (enough for a ZFS raidz2 array). I'll probably wait and go Rome or new Threadripper instead to get more lanes though.

    If you use the third m.2 slot it disables two Sata ports
  • hubick - Monday, August 12, 2019 - link

    Uhg, that sucks. Thanks for the tip though. In advance of a new system, I grabbed a couple Corsair MP600 I'm running in RAID 0 for my OS now, on PCIe 3.0 though, which is mainly what I'd want the first two slots for - but I'd really like a third to house a ZFS slog device. All the more reason to wait for Threadripper/Rome I guess.
  • mjz_5 - Monday, August 12, 2019 - link

    Wonder why they included a U.2 port. Would rather have another M.2 port or at least run the second one at full X4
  • haukionkannel - Monday, August 12, 2019 - link

    U2 is defacto in workstation environment. M2 is more towards the normal consumers.
  • DanNeely - Monday, August 12, 2019 - link

    To an extent I think it's like Sata-Express a few years ago; the multi-year lead time on board design means they need to guess what adoption will look like a few years in advance of selling the product.

    U.2 does have a presence in the highest end enterprise segment; but I suspect that if they knew it was going to be MIA in the prosumer market they probably would've switched its lanes with an onboard m.2.
