Our take on the ASUS ROG Zenith II Extreme Alpha

The ROG Zenith II Extreme Alpha is ASUS's flagship motherboard for AMD's Socket sTRX4 Threadripper platform. It pairs the TRX40 chipset with eight DDR4 slots, four PCIe 4.0 x16 slots, two M.2 sockets and onboard Wi-Fi and Bluetooth, plus a large passive cooling array over the power delivery. It suits workstation and high-end desktop builders who need many cores, lanes and memory capacity in one board. Against other TRX40 boards it stands out for its oversized power stages and 16-phase design, but it is an E-ATX board with a narrow audience and a heavy feature set most gamers will not use.

Pros
  • 16-phase power delivery with strong VRM cooling for overclocking
  • Four PCIe 4.0 x16 slots for multi-GPU and add-in cards
  • Eight DDR4 slots supporting up to 256 GB
  • Two M.2 sockets plus onboard Wi-Fi and Bluetooth
  • Extensive USB and fan headers, including USB-C and optical S/PDIF
Cons
  • E-ATX size needs a large case and careful clearance checks
  • Only two 4-pin fan headers onboard, so most builds need a hub or splitter
  • sTRX4 socket limits CPU choice to Threadripper 3000-series chips
  • Features and cost are overkill for gaming-only builds
  • Large passive heatsinks can crowd the board and complicate cable routing

What reviewers say

Owners and reviewers treat the Zenith II Extreme Alpha as a premium TRX40 board with excellent power delivery and cooling for overclocked Threadripper chips. Praise centers on build quality, the VRM and the lane count; complaints focus on its size, the limited fan headers and the platform's narrow CPU support.

What people mention
  • Power deliveryPraisedReviewers say the 16-phase VRM handles overclocked Threadripper chips without throttling.
  • SizeCriticisedOwners note the E-ATX board needs a large case and can crowd components.
  • Fan headersCriticisedBuilders complain two 4-pin fan headers are too few and force splitters or hubs.
  • ExpansionPraisedFour PCIe 4.0 x16 slots and two M.2 sockets are called generous for workstation use.
  • PlatformMixedThe sTRX4 socket is praised for core count but criticized for a short, costly upgrade path.

Questions and answers

Which CPUs does it support?
It uses AMD Socket sTRX4 and supports Ryzen Threadripper 3000-series processors. It does not take older TR4 chips or mainstream Ryzen CPUs.
How much memory can it hold?
Eight DDR4 slots support up to 256 GB, with rated speeds up to 4733 MHz depending on the kit and CPU.
Does it fit a standard ATX case?
No. It is E-ATX, so check your case's motherboard support and clearance around the heatsinks before buying.
How many M.2 drives can I install?
Two M.2 sockets are onboard, accepting 2242, 2260 and 2280 drives. More storage goes through the SATA III ports.
Is Wi-Fi built in?
Yes. Onboard Wi-Fi and Bluetooth are included, along with RJ45 LAN and optical S/PDIF on the rear panel.
Is it worth it over a cheaper TRX40 board?
If you overclock a high-core Threadripper or need four PCIe 4.0 x16 slots, the stronger VRM and cooling justify it. For a stock-speed build, a simpler TRX40 board covers the basics.
Where is the ASUS ROG Zenith II Extreme Alpha cheapest?
At Newegg, for $1,299.99, as of our latest check.
