Question 1

Can the expansion card cause system crashes?

Accepted Answer

There are reports of inconsistent performance and even potential damage to system components.

Question 2

Is the card compatible with Asus motherboard B550 Plus?

Accepted Answer

There are multiple B550 Plus motherboards.  You need to see if yours have the Thunderbolt 14-1 header.

Question 3

Is this card compatible with the Pro WS TRX50-SAGE WIFI?

Accepted Answer

Almost definitely not.  Unless you have an Asus motherboard that explicitly supports this, then stay away.

Question 4

Has anyone tried this with an Audio Interface like Presonus or Steinberg?

Accepted Answer

Yes.  I use this thunderbolt card with a Presonus Quantum 4848 interface and Studio One.  For the most part it has done the job reliably.  Occasionally on the first connection attempt I cannot pass audio and I need to restart Studio One and the Quantum interface, after which it works like a charm.  I believe this issue is more of a Presonus driver problem than it is anything to do with the thunderbolt card itself.  I also use this card to interface to a network attached storage device, where I can get very decent throughput to a RAID10 storage array.  For reference I am using this card with an ASUS motherboard (Z690 chipset).  I would have preferred to have thunderbolt integrated into the motherboard but at the time that I was in the market there was not a good option available with the features I needed.

Question 5

So this is the thunderbolt thing adaptor that my Asus Z590-P MB manual refers to?

Accepted Answer

The ASUS ThunderboltEX 4 is compatible with ASUS Intel 500 series and later models with a 14-1 pin Thunderbolt header, which includes the Asus Z590-P motherboard.

Question 6

Will this work on the ROG Crosshair VIII Hero (WiFi)?

Accepted Answer

The ASUS ThunderboltEX 4 is compatible with ASUS Intel 500 series and later models with a 14-1 pin Thunderbolt header. The ROG Crosshair VIII Hero (WiFi) is an AMD motherboard, not an Intel 500 series, so it is not listed as compatible.

the Motherboard needs a Thunderbolt 14-1 header
x570 not supported
