Chapter 4: Motherboard Connections
SATA Ports
The H12SSFR-AN6 has two standard onboard SATA3 ports (I-SATA0~1). I-SATA0 and
I-SATA1 are standard SATA 3.0 ports.
NVMe Ports
The JNVME1 ~ JNVME4 connections are NVMe ports, which provide high-speed, low-latency
PCIe 4.0 x4 connections directly from the CPU to NVMe SSDs (Solid State Drives). This
greatly increases SSD data-throughput performance and significantly reduces PCIe latency by
simplifying driver/software requirements resulting from the direct PCIe interface from the CPU.
TPM Header/Port 80 Connector (TPM Port)
The JTPM1 header is used to connect a Trusted Platform Module (TPM). A TPM is a security
device that supports encryption and authentication in hard drives. It enables the motherboard
to deny access if the TPM associated with the hard drive is not installed in the system.
