Currently, there are very few mainboards or none that have a TPM 2.0 module permanently installed. This refers to mainboards for self-build PCs. However, some offer the option of buying a TPM 2.0 module as a separate module and retrofitting it on the board in a slot provided for this purpose (https://de.wikipedia.org/wiki...).

In addition to physical TPM modules, there are also fTPM (firmware TPM, called PTT at Intel).

Intel and AMD have been integrating TPM version 2.0 into their CPUs for several years. To be able to use this, the BIOS of the PC/notebook must support it and it must be activated there.

Intel CPUs from the 8th generation onwards usually have TPM integrated. Intel calls this PTT (Platform Trust Technology). AMD has integrated TPM as fTPM in the CPUs since the use of Socket AM4 from 2016.

FAQ about TPM 2.0 https://www.heise.de/select...

Before buying a TPM module for the mainboard, which may be unnecessary, you should check whether the BIOS allows fTPM via CPU and whether this only needs to be activated.

Help pages for (f)TPM from various mainboard manufacturers:
ASUS https://www.asus.com/ch-de...
MSI https://www.msi.com/blog...
Gigabyte https://www.gigabyte.com/Press...
Asrock https://www.asrock.com/support...

In the BIOS of the ASUS ROG MAXIMUS XIII HERO, the TPM "function" can be activated as follows:
-Advanced\
-PCH-FW Configuration\
-Enable Intel Platform Trust Technology (PTT).


So you don't have to buy a module.

PCGH quote: Asus and Asrock have now also commented on the motherboard support for Windows 11, stating that no TPM 2.0 module is required, but only the CPU must support the standard. The support is listed in detail according to platform or chipset - the manufacturers also explain how to activate TPM 2.0.
