B8261T85E8HR-2T-N-HE (TN85-B8261)
2U MiTAC AI SERVER / GPU SERVER / HPC / AMD EPYC / LLM INFERENCE
The MiTAC B8261T85E8HR-2T-N-HE (TN85-B8261) is a 2U rack-mount AMD EPYC GPU server supporting dual AMD EPYC 9005/9004 series processors on Socket SP5 with 24 DDR5 DIMM slots up to 6400 MT/s. It accommodates two 600W or four 400W double-width GPUs, including the NVIDIA RTX PRO 6000 Blackwell Server Edition, across four full-height PCIe Gen 5 x16 slots and two half-height slots, with eight front NVMe U.2 hot-swap bays and 1+1 redundant 2700W power supplies. The 2U height delivers meaningful GPU inference density where rack space is constrained.
