TPM-SPI – ASUS TPM 2.0 Module – 14-1 Pin SPI_TPM Header (Discrete Hardware Security)
Compact ASUS discrete TPM 2.0 card for motherboards that use the SPI_TPM 14-1 pin header. Provides hardware root-of-trust for BitLocker, Secure Boot, and platform attestation.
Description
This module plugs straight into a board’s SPI_TPM header and exposes a TPM 2.0 device to firmware/OS. It’s ideal for enabling Windows features that require a discrete TPM or for replacing a missing module on compatible ASUS motherboards.
Technical Specifications

- 90MC07D0-M0XBN1 (ASUS MPN)
- 90MC07D0-MVXBN0 (boxed/retail code seen on packaging)
(Same type/fit — ensure your board specifically requires SPI_TPM (14-1). Not compatible with ASUS TPM-M R2.0 (LPC 14-1) or TPM-L R2.0 (20-pin).)
✅ Confirmed Compatibility
Please note that the following list is not exhaustive. Compatibility depends on your system’s specific configuration. It’s essential to verify compatibility with your system or enclosure manufacturer prior to installation.
✔️ ASUS motherboards that specify a SPI_TPM (14-1) header and list TPM-SPI in their manual/QVL
✔️ Intel and AMD desktop/workstation platforms requiring a discrete SPI TPM 2.0 module
✔️ Systems enabling BitLocker/Device Encryption, Secure Boot, and attestation features
☑️ Key Features
- ☑️ Hardware root-of-trust for encryption keys and credentials
- ☑️ Direct 14-1 pin SPI_TPM plug-in—no cable required
- ☑️ TPM 2.0 support for modern OS security and compliance workflows
- ☑️ Compact, low-power design suitable for tight motherboard clearances
⚙️ Fit Notes
- Header type matters: This is SPI_TPM (14-1). It is not the LPC TPM-M R2.0 (14-1) or the TPM-L R2.0 (20-pin) server-style module.
- Pin-1 orientation: Align the keyed header; never force insertion.
- UEFI setup: Enable Discrete TPM (disable PTT/fTPM if your board requires choosing one path).
- Reuse: If moving to another system, clear/initialize the TPM in firmware before enabling BitLocker or similar features.
