NEW MSI TRX4 MOTHERBOARDS

MSI tweeted news of three new motherboards for the AMD Threadripper processors. All three motherboards are standard ATX. The motherboards have a new socket TRX4 to accommodate 128 lanes of PCI Express 4.0.

All three boards need dual EPS12V cables to provide enough power to the slots. MSI has a PCIe M.2 card that is included with TRX40 PRO 10G to add more SSD capacity. The 10GBASE-T card could be replaced by a USB 3.2 adapter which would eliminate the need for a slot.

The TRX40 PRO 10G has a PCIe x1 slot for the Firewire card. 16-channel digital audio mixers can be fed via Firewire into professional tools. 12G-SDI cards are used for professional video needs and they need a fast x8 slot to handle uncompressed video streams. USB Firewire solutions have not worked so far.

The main PCIe 4.0 slots are wired as x16, x8, x16, and x8. The PCIe x1 slot operates at PCIe 3.0 speeds.

The boards can handle dual graphics cards but support today for such setups is increasingly rare. Modern cards are powerful enough to handle the job.

There are two CPU models, the 3950X and the 3970X shown initially. The 3990X was added subsequently.

MSI includes a discrete PCIe Ethernet card rather than integrating it directly on the motherboard. The other card is a M.2 adapter to allow users to install more SSD products.

Realistically with the TRX4 motherboards its advisable to use a 1000W or better PSU. The larger capacity is needed as the AMD processors use over 200W each and the PCI slots can draw power with workstation video class cards. Dual cards would mandate a 1200W class PSU.
