1. ATX power connectors (24-pin EATX_PWR1, 8-pin EATX_PWR2)
These connectors are for ATX power supply plugs. The power supply plugs
are designed to fit these connectors in only one orientation. Find the proper
orientation and push down firmly until the connectors completely fit.

2. TPM connector (20-1 pin TPM1)

securely store keys, digital certificates, passwords, and data. A TPM system
also helps enhance network security, protects digital identities, and ensures
platform integrity.

For a fully configured system, we recommend that you use a power supply
unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version)
and provides a minimum power of 230W.
We recommend that you use a PSU with higher power output when
configuring a system with more power-consuming devices. The system
may become unstable or may not boot up if the power is inadequate.
