Supermicro
Supermicro GPU Servers
Supermicro is where most of the configuration flexibility in this market lives. The same 8-GPU HGX baseboard is available air-cooled, direct-liquid-cooled, with BlueField DPUs, or with a different CPU vendor entirely — and the PCIe platforms cover everything from 4x H100 NVL down to dense L40S inference nodes.
That breadth is the reason to buy it and the reason it needs specifying carefully. We quote the exact SKU, not a family name, so what arrives is what was priced.

Supermicro GPU Servers we configure and supply

What we need to quote accurately
A configuration quote takes minutes when these are known and days of back-and-forth when they are not. You do not need all of them to start — send what you have.
- The workload: model sizes, training or inference, and expected concurrency
- Node count, and whether this is a single system or a scaling cluster
- Rack power and cooling available per rack, and inlet temperature
- Existing estate — the vendor and management tooling you already run
- Network fabric: InfiniBand, Ethernet, and the speed you are standardised on
- Timeline, and whether the budget is approved or being built
How we quote
- 1
Send the requirement
An email, a bill of materials, or a rough description of the workload. All three work.
- 2
We validate the configuration
Accelerator, chassis, fabric, power and cooling checked against each other before anything is priced.
- 3
Itemised quote within 48 hours
Line-by-line pricing, current availability and lead time, with warranty terms stated.
Supermicro GPU server — buyer questions
Air-cooled or liquid-cooled?
Decided by your facility, not by preference. An 8-GPU SXM node at sustained full utilisation is a thermal load many rooms cannot take air-cooled at rack density. Direct liquid cooling raises the ceiling substantially but needs facility water and changes the installation. Tell us your rack power budget and inlet temperature and we will tell you which is realistic.
What is the difference between the 821GE-TNHR and the 4125GS-TNRT?
The 821GE-TNHR is an 8U HGX platform with SXM modules on an NVLink baseboard — for training that spans GPUs. The 4125GS-TNRT is a 4U PCIe system taking H100 NVL cards on dual EPYC — for inference and fine-tuning that fits within one or two GPUs. Different jobs, not different tiers.
Can you supply Supermicro systems with InfiniBand pre-configured?
Yes. We quote the adapters, switches, cables and rail-optimised layout with the nodes, because a training cluster ordered without its fabric is not a cluster.
