ASRock Z890 Pro RS

Name: ASRock Z890 Pro RS
Brand: ASRock
SKU: 46030

Manufacturer: ASRock

The ASRock Z890 Pro RS is an ATX-form-factor motherboard built around the Z890 chipset and the LGA 1851 socket, making it compatible with Intel's current processor lineup for that platform. The board measures 305 mm by 244 mm and ships with a three-year warranty, along with RGB lighting and support for straightforward overclocking through the BIOS. It does not include integrated Wi-Fi or Bluetooth, so wireless connectivity relies on a separate adapter or expansion card.

On the memory side, the board accommodates up to 256 GB of DDR5 across four slots in a dual-channel configuration, with a standard rated speed of 5600 MHz and overclocked support reaching 8666 MHz. Expansion is handled by one PCIe 5.0 x16 slot alongside two PCIe x4 slots and one PCIe x1 slot, while storage options include four SATA 3 connectors and four M.2 sockets with full RAID 0, 1, 5, and 10 support. The rear I/O provides two USB 4 40 Gbps ports, two Thunderbolt 4 ports, one USB 3.2 Gen 2 Type-A port, an HDMI 2.1 output, one DisplayPort, and a single RJ45 ethernet jack, complemented by 7.1-channel audio across three connectors.

Pros

Four M.2 sockets offer substantial NVMe storage expansion without relying on adapter cards
Two USB 4 40Gbps ports and two Thunderbolt 4 ports provide high-bandwidth connectivity for fast external devices
DDR5 memory can be overclocked up to 8666 MHz across four slots, with a maximum capacity of 256 GB
Eight fan headers give considerable flexibility for managing airflow and thermal control inside the case
Full RAID 0, 1, 5, and 10 support allows for both performance and redundancy configurations across the SATA storage array
A three-year warranty provides longer coverage than the typical two-year period common in this category

Cons

No built-in Wi-Fi or Bluetooth means wireless connectivity requires a separate adapter or expansion card
There is no dual BIOS, so recovering from a failed firmware update requires a manual process
The clear CMOS function is not easily accessible, complicating BIOS recovery in certain situations
No USB-C ports in the USB 3.2 range limits rear-panel options for modern peripherals that use Type-C at that speed tier
ECC memory is not supported, ruling out use cases that require error-correcting RAM

Who is this for?

This board is well-suited to enthusiast desktop builders who want a platform capable of handling high-speed DDR5 memory and PCIe 5.0 storage or graphics, particularly those pushing overclocked RAM configurations up to 8666 MHz. The four M.2 sockets, broad RAID support, and eight fan headers make it a practical choice for users building content creation or data-intensive workstations that require flexible storage arrangements and thorough thermal management. The inclusion of Thunderbolt 4 and USB 4 40Gbps ports also makes it a strong fit for users who regularly connect high-bandwidth peripherals such as fast external drives or docking stations.

Who is this NOT for?

Users who rely on wireless connectivity out of the box will find this board lacking, as there is no integrated Wi-Fi or Bluetooth, requiring a separate solution to cover those needs. It is also a poor match for environments where ECC memory or system redundancy at the firmware level is a requirement, since neither ECC support nor dual BIOS is available. Additionally, those who need a straightforward BIOS recovery process may find the absence of an easy CMOS reset option inconvenient during troubleshooting.
