AMD PSP Device is the Windows entry for AMD’s platform security processor and its driver. PSP stands for Platform Security Processor. Seeing that name in Device Manager is normally expected on supported AMD hardware; the name alone is not a sign of malware.
What does AMD PSP do?
AMD now commonly uses the name AMD Secure Processor. It is dedicated security hardware within the processor’s system, used for security and boot-related tasks. AMD describes its role in a hardware-based root of trust: a starting point for checking that parts of the startup process can be trusted.
That does not mean every application runs inside a separate protected processor, or that the PC is immune to malicious software. The available protections depend on the processor, firmware, operating system and device design. AMD’s security technology overview explains how the processor fits alongside other protections.
What does “AMD PSP 11.0 Device” mean?
Windows may show a versioned device name, such as AMD PSP 11.0 Device. Read it as the name of a hardware/driver entry, not as an instruction to install a file with the highest number you can find online.
To inspect it, open Device Manager > Security devices, select the PSP entry and open Properties. Record the device status and any error code. The Driver tab shows the installed driver information.
Do you need an AMD PSP driver?
| What you see | Next step |
|---|---|
| Device status says it is working correctly | Use the normal supported update route; no random replacement is needed. |
| A warning icon or error code | Record the code, PC model, chipset and Windows version before troubleshooting. |
| An unknown security-related device after reinstalling Windows | Check the PC maker’s driver page and the supported AMD chipset package. |
| A site offers a standalone “PSP fixer” | Use the manufacturer or AMD support instead of an unverified driver download. |
AMD lists PSP among the drivers in its Ryzen chipset package release notes. Product and Windows support vary, so one package is not right for every AMD PC.
How to update it
- Identify your exact PC or motherboard model and Windows version.
- For a laptop or prebuilt PC, check its manufacturer’s supported driver package first.
- If using AMD’s package, choose the correct chipset on AMD Drivers and Support.
- Read the supported products and installation instructions, install the package, and restart when prompted.
- Check Device Manager again and keep the error details if it still fails.
AMD’s chipset installation guide covers its package workflow. Do not disable the security device merely to hide an error.
A PSP driver update is not a BIOS update
The Windows driver and the motherboard‘s firmware are different software layers. A security advisory may require one or both, depending on the affected product. Use the exact model’s support instructions. Our AMD AGESA and BIOS guide explains why firmware from another board is not interchangeable with yours.
