PCIe 5.0 ready

Faster storage, graphics and networking capabilities PCI Express® (PCIe®) 5.0 delivers 32GT/s bandwidth, which is twice the speed of PCIe 4.0, and offers lower power consumption, better land scalability and backwards compatibility. ASUS servers are PCIe 5.0 ready with scalability design to satisfy the increasing workloads for modern data center.

ASUS RS300-E12-RS4-1G4 1U Rackmount Entry Server
Redundant Platinum PSU support

RS300-E12-RS4 supports redundant 450W 80 PLUS Platinum power supplies, which are 96%+ efficient, directly reducing operating costs and capital expenses. The 1+1 power-supply design allows the server to keep working even if one power supply requires maintenance, enabling uninterrupted operation.

ASUS RS300-E12-RS4-1G4 1U Rackmount Entry Server
Enhanced security

RS300-E12-RS4 servers integrate PFR FPGA as the platform Root-of-Trust solution for firmware resiliency to prevent from hackers from gaining access to infrastructure. ASUS security solutions are fully compliant with the 2018 National Institute of Standards and Technology (NIST) SP 800 193 specification.

In addition, all RS300-E12-RS4 servers also include support Trusted Platform Module 2.0 (TPM 2.0) to secure hardware through integrated cryptographic keys and offer regular firmware update for vulnerabilities.

* Platform Firmware Resilience (PFR) module must be specified at time of purchase and is factory-fitted. It is not for sale separately.
