One of the more frustrating Windows 11 hardware requirements is the need for either firmware TPM or a Trusted Platform Module 2.0 (TPM).Here’s a guide on where to buy the latter.

Of course, there is a way to bypass the Windows 11 TPM, RAM and CPU requirements with a simple free utility, but if you’d rather fulfill the official requirements for this and any future OS updates, this is the way to go.

However, to anyone who’s reading this, there’s a good chance you either don’t need one or can’t install one. Let’s start there and establish whether it’s a must-have.

Buying guide for TPM 2.0

Before you shop, you should first check if your system already has either firmware TPM enabled or an existing TPM chip already installed.

To check if you have firmware TPM, you’ll need to access your UEFI settings in your BIOS. How to do this differs across manufacturers, so check your motherboard’s manual for more details. There is some common parlance you’ll want to keep an eye out for, though. AMD motherboards tend to call their firmware TPM solutions “fTPM,” while Intel boards tend to call them “PTT.”


To check if you already have a physical TPM chip installed, just open your run utility (Win key + R), type “tpm.msc” in the box, and his Enter. The TPM Management tool will open, and should tell you whether “The TPM is ready for use” or “Compatible TPM cannot be found.”

Where to buy a TPM 2.0 for Windows 11

Stock has been running dry since the TPM requirement announcement back in summer, but more are starting to appear at their standard price range of $15-30. You can start by searching at these retailers.

  • Amazon
  • B&H
  • eBay
  • Newegg

We wish we could say more, but our main advice is to be patient. Limited supply may cause the prices to rise at times, so sign up for some stock notifications for the TPMs that your system supports and wait for that price to come down to a more reasonable level.
