Designed to support demanding applications such as media streaming, cloud computing, and virtualization, the barebone RS500A-E12-RS12U-12W12B Rackmount Server from ASUS allows you to fully customize its performance while having room to scale as your needs grow. Fitting 1 RU rackmount space with its included rails, this system features a single AMD EPYC 9004 series processor socket and twenty-four 12-channel DDR5-4800 RDIMM memory slots to support demanding applications, including AI workloads and 3D design.

The front panel includes 12 hot-swappable 2.5" NVMe drive bays. There are also two internal M.2 22110 PCIe 5.0 SSD slots available. Up to 6144GB of memory may be installed, and multiple PCIe Gen 5 x16 and x8 slots are available for up to four two single-slot GPUs and other compatible expansion cards. The two Gigabit Ethernet LAN ports allow you to quickly integrate the server with your network. This server includes dual 1200W 80 PLUS Platinumpower supplies with the second one providing failover redundancy.
