Mellanox (NVIDIA Networking)
Mellanox ConnectX-5 adapters in 25G and 100G: the cards that made 25/100GbE practical for storage and AI fabrics. RoCE/RDMA offload is the reason to choose them over a plain NIC.

Check the PCIe generation and lane width of the card against the slots you have free — a 100G card in a narrow Gen3 slot will not deliver line rate.

If you are replacing a part rather than building new, send the part number printed on the old unit and the platform it sits in. Most Mellanox (NVIDIA Networking) buying mistakes come from matching the brand and the capacity but not the generation, the interface or the rank - and those are exactly the details we check before quoting.
How we check Mellanox (NVIDIA Networking) parts before they ship
- 1The marking, part number or label is read and photographed, and checked against the specification on your order — not against what the previous supplier said.
- 2Every unit is tested on a reference platform of the correct generation, with the test result logged per serial.
- 3Condition is stated line by line before you commit: new, OEM tray, or decommissioned pull.
- 4Every part ships with a 1-year written warranty and the diagnostic record for that unit.
Frequently asked questions
What Mellanox (NVIDIA Networking) models do you supply?
We currently publish 2 Mellanox (NVIDIA Networking) model pages covering . The list above links every one; if the exact model you need is not listed, send the part number and we will quote what is available on the secondary market.
Are these Mellanox (NVIDIA Networking) parts new or refurbished?
Both, and the condition is stated line by line before you order — new, OEM tray, or decommissioned pull. Every part is tested and carries a 1-year written warranty; pulls are graded and documented rather than described as "used".
How do I know the Mellanox (NVIDIA Networking) part fits my platform?
Send the platform model or the old part number. For CPUs the socket and BIOS revision decide fit; for memory the module type, organisation, rank and speed decide it; for drives the interface and bay type; for GPUs the power and slot budget. We confirm the fit before the order is final.
Why is there no price on this page?
Secondary-market pricing for these parts reprices weekly, and a printed figure would be stale faster than you could act on it. Send the quantity, condition and destination and we quote against confirmed stock with the date the quote holds until.
Do you ship Mellanox (NVIDIA Networking) parts worldwide?
Yes. We ship from the Hong Kong warehouse with full export documentation, typically 3-7 days by air, and the tracking is shared with the invoice.
What is the lead time on Mellanox (NVIDIA Networking) stock?
Stock items ship from Hong Kong within 1-3 working days of payment, and air freight to most destinations takes 3-7 days with full export documentation. If you have a hard deadline, tell us the date and we will confirm whether the stock and the route can meet it before you commit.
Can you supply matched sets of Mellanox (NVIDIA Networking) parts?
Yes - matched CPU pairs from one lot, memory kits sized to the channel population, and matched drive batches for arrays. Tell us the population and we quote it as a set rather than as loose units, which is also how we check that it will train on your platform.
