Used NVIDIA A100 40GB: Price, Listings & Specs | BreezeWish
The NVIDIA A100 40GB is the earlier Ampere memory size: 40 GB of HBM2. NVIDIA's datasheet lists 1,555 GB/s of memory bandwidth for that memory configuration, 400 W for the SXM module, and 250 W for the PCIe card. The SXM product uses third-generation NVLink. The PCIe card uses PCIe Gen4 [S1]. It is the volume card from the first A100 servers, and it is still widely decommissioned.
Bandwidth, capacity, and the usual sale price differ from the 80 GB part. A missing label does not change the module. On BreezeWish a line matches this page when the model text or the memory field says 40 GB, and it matches the 80 GB page when the memory is 80. A bare "A100" with no memory is unmatched until the seller adds the number. These cards are listed for sale by the seller, at the seller's price.
Lots are loose modules, PCIe cards, and partial HGX boards. A 40 GB SXM module belongs on a 40 GB HGX board. Mixing 40 GB and 80 GB modules on one baseboard is something to ask the seller about before you bid, not something to discover at install.

Buying checklist
- SXM versus PCIe, and whether the baseboard or NVLink bridge is in the lot.
- Part numbers on the module and the board.
- Serials, and a seller-provided nvidia-smi or DCGM report.
- Warranty terms the seller will actually sign.
- Lien and title documents from the seller.
- Export and end use. Buyers are US businesses.
- Who ships, and who insures the freight.
- Payment. Independent escrow services are the parties' choice.
Ask for the part number and a seller-provided nvidia-smi or DCGM report that shows 40 GB, not 80. Ask whether anyone claims a lien, what warranty the seller will put in the contract, and whether the power cables and NVLink bridge ship with a PCIe pair. Serials should be listed before money moves. Independent escrow services are the parties' choice.
Selling notes
Write "A100 40GB" in the model field and set memory to 40. Choose SXM4 or PCIe. Buyers searching the 80 GB page will not see a 40 GB lot. If you are selling a whole DGX or HGX, say how many of the GPUs are 40 GB. Condition and whether the board is complete change the bid more than a round number in the title.
FAQ
Who am I buying from?
You are buying from the seller on the listing. BreezeWish is a venue that connects US business buyers and sellers. It is not a party to the sale. Payment, title transfer, and shipping are handled by the parties. BreezeWish never holds the funds or the hardware.
Why isn't this grouped with the A100 80GB?
NVIDIA specifies different memory, bandwidth, and power for the 40 GB and 80 GB products [S1]. The secondary market prices them apart. The pages follow that split.
What report should I ask for?
A seller-provided `nvidia-smi` or DCGM report that shows the product name and 40 GB of memory, plus the serials. BreezeWish does not run that test.
What are the export rules?
US buyers only, on this market. The hardware falls under ECCN 3A090. Consult counsel before any export. This page is not legal advice [S2].
When will I see a median price?
After five verified completed deals for the A100 40GB. A thinner history stays as a count, not a made-up band.
