The Supermicro CSE-113AC2-605WB is a premium 1U rackmount chassis engineered for high-density enterprise environments requiring flexible I/O expansion and tiered storage performance. Designed specifically to support Supermicro proprietary WIO (Wide I/O) motherboards, this chassis overcomes standard 1U limitations by accommodating two full-height, full-length expansion cards alongside one low-profile card. This unique architecture makes it an ideal foundation for networking appliances, virtualization nodes, and high-performance database servers that demand significant add-on card capacity in a compact footprint. Storage versatility is a standout feature, driven by an 8-port hybrid backplane that supports 12Gbps SAS3 throughput. The configuration allows for six standard SAS3/SATA3 drives and two hybrid ports capable of supporting NVMe, enabling engineers to deploy ultra-fast caching layers alongside high-capacity storage. Power efficiency is maximized through a 600W Platinum Level power supply, achieving 92% efficiency to reduce operational costs in large-scale data center deployments. The chassis features a robust thermal design with counter-rotating PWM fans, ensuring stability for high-TDP processors.
