Network Cards
1/10/25GbE network cards and converged adapters from Intel, Broadcom, Mellanox, and Dell — tested pulls with SFP+ and Base-T options for servers and workstations.
Server Network Cards — 1GbE to 25GbE NICs
Rack-pulled, tested network adapters from Intel, Broadcom, Mellanox/NVIDIA, and Dell — the affordable way to take a server from gigabit to 10GbE or 25GbE. We stock PCIe NICs, blade mezzanine cards, and OCP/rNDC daughter cards for Dell PowerEdge and HPE ProLiant platforms.
Choosing a NIC
- Speed and media: 1GbE and 10GBase-T run over copper RJ45; 10/25GbE SFP+/SFP28 ports take DACs or fiber transceivers — make sure the optic matches the NIC and the switch at both ends.
- Form factor: standard PCIe cards fit any tower or rack server; rNDC and OCP mezzanine cards drop into the dedicated network slot on Dell and HPE rack platforms.
- Offload features: RDMA/RoCE, SR-IOV, and iSCSI offload matter for virtualization hosts and storage networks — check the controller chip, not just the port count.

Quick Answers: Buying from PCSP
SFP+ or 10GBase-T — which should I buy?
Match your switch first. SFP+ runs cooler, adds less latency, and links over cheap DAC cables in-rack or fiber between rooms — but every port needs a transceiver or DAC. 10GBase-T uses ordinary RJ45 over Cat6a wiring, which keeps small deployments simple if your switch has copper ports. Mixed environment? Ask us before you buy.
Will any optic work in this NIC?
No — many adapters check vendor coding, and Intel NICs in particular often refuse non-Intel-coded modules out of the box. The optic also has to agree with whatever sits at the far end of the link. Tell us the NIC and the switch and we will confirm the whole path before you order.
What is an rNDC or OCP card, and do I have the slot for one?
They are network daughter cards that drop into a dedicated slot on Dell and HPE rack servers — not a standard PCIe slot, and not interchangeable with one. If you are unsure which network slot your server has, send us the model and we will tell you which form factor fits.
How are used network cards tested, and what if one arrives faulty?
Every adapter is brought up and link-tested before listing. If a card still arrives dead or not as described, 90-day returns cover it at our expense. In-stock cards ship the same business day on orders before 1:00 pm EST, with free ground shipping in the contiguous United States.
