Dual EPYC 9474F 8U GPU server
The Supermicro AS-8125GS-TNHR-G1 is an 8U rack system built for high-density compute. It ships with two AMD EPYC 9474F processors, each running 48 cores at 3.60 GHz, and 2.3 TB of DDR5-5600 memory operating at 4800 MT/s. Eight NVIDIA H200 GPUs with 141 GB each provide massive parallel throughput for AI training and HPC workloads.
Sustained load behaviour
Ten hot-swap fans with optimal speed control move air across the GPUs and CPUs during extended runs. Six 3000 W Titanium-level power supplies share the load, keeping voltage stable when all eight GPUs and both CPUs draw maximum power. System overheat and power-fail LEDs give immediate visual warning if thermal limits are approached.
Installation and common issues
The chassis offers twelve front hot-swap 2.5-inch NVMe bays, four additional NVMe bays, two SATA bays and one M.2 NVMe slot for storage expansion. Eight 400 G OSFP ports require matching transceivers and cabling that are not included. Rack rails and 8U clearance must be verified before delivery; the unit weighs substantially more than a standard 8U server.
