Broadcom 57414 Dual-Port 25GbE SFP28 (BCM57414)
A dual-port 25GbE SFP28 adapter on the BCM57414 controller with a PCIe 3.0 x8 host interface — the OEM-standard 25G card that ships in huge volumes inside Dell, HPE and Lenovo rack servers, which is exactly why used supply is deep and cheap. One warning before you buy on price alone: the 57414 family has several single-port and dual-port OPN variants and they are not the same card. Everything below is the dual-port 25GbE SFP28 configuration.

Broadcom 57414 — Dual SFP28, PCIe 3.0 x8
Two SFP28 cages at 25GbE each on a PCIe 3.0 x8 host interface. This page and our stock cover the dual-port 25GbE SFP28 configuration only. Single-port variants and different OPN tail codes exist in the same family at materially different prices — always confirm the OPN before ordering.
Read the OPN, Not Just the Name
The OPN printed on the card is the only reliable identifier. OEM-partner versions of the same silicon carry different tail codes and different bracket or airflow hardware, and a single-port part can be listed under the same '57414' name as the dual-port card. We photograph and record the OPN of every unit we ship.

The 57414 is the card you find in volume inside Dell and HPE rack servers, which makes it the cheapest route to 25G in the used market — but it is also the card most often bought wrongly, because '57414' is a family name rather than one part number. This page covers the dual-port 25GbE SFP28 configuration; single-port parts and different OEM tail codes exist and sell for less. Before ordering, confirm the OPN with us. It is a standard fit in our PowerEdge R750 and ProLiant DL380 Gen10 configurations, and if you would rather have a Mellanox card with a documented firmware path, compare against our ConnectX-5 25G page.
Transparent Pricing
2026 Reference Pricing — and Why You Must Send Your OPN
Tracked live in the September 2026 collection round — nine asking-price data points. Read this section before you compare us to any other listing, because the spread here is not condition and it is not seller quality: it is a wide family of different part numbers sharing one name.
Dual-Port 25GbE SFP28 — the configuration this page covers
$47–$75
Our quoting band for the genuine dual-port 25GbE SFP28 card. The tracked data points in this part of the range are $47.99, $51.69 (refurbished), $54.99, $59.00, $61.90, $69.88, $69.99 and $75.00. This is what a real dual-port 57414 costs and it is what we quote.
Single-Port / Parts-Pull Variants — cheaper, and not the same card
from ≈$25
The $24.99 data point at the bottom of the tracked range is almost certainly a single-port part or a bare pull rather than a dual-port card. Single-port and different-OPN variants in the 57414 family are legitimate products, but they are not interchangeable with the dual-port card this page describes. If you are seeing sub-$40 prices for a '57414', that is usually why.
OEM-Partner Versions and Bundle Differences
varies by OPN
Dell, HPE and Lenovo partner versions of the same controller carry different OPN tail codes and can differ in bracket, airflow hardware and firmware branding. Price follows the OPN, not the marketplace title — which is why we confirm the OPN with you before quoting rather than matching a headline number.
Asking prices, not transaction prices — volume deals typically close 5–15% below asking. Nine data points tracked. Source channel: eBay, sorted by price+shipping, lowest first (first-screen listings). Collected Sep 20, 2026. This entry corresponds to section 39 (Broadcom 57414 25G SFP28, BCM57414) of the HKCHL used-server price index. Variant warning from the collection notes: the 57414 family includes single-port and dual-port parts and multiple OPN tail codes with a wide price spread — the lowest tracked price is not comparable to the dual-port card. Send us your OPN and we confirm the exact card before quoting.

Quality Process
What We Test Before a Broadcom 57414 Ships
OPN and Variant Confirmation
The OPN on the card is read and matched against the configuration you ordered. This is the first check specifically because the 57414 family contains single-port and dual-port parts under one name — a wrong variant is the single most likely failure mode on this card.
Per-Port 25G Link-Up
Both SFP28 ports are brought up individually at 25GbE against a reference switch. On a card this cheap, a dead second port is the fault we look for hardest.
RoCE / RDMA Bring-Up
RDMA over Converged Ethernet exercised between two hosts. The BCM57414 supports it and it is a real reason to choose this card, so we verify it rather than trust the datasheet.
Cage and Latch Inspection
SFP28 cage latches and retaining tabs checked for damage or distortion. These cards come out of dense OEM chassis where cages take abuse, and a loose cage produces intermittent link faults that get misdiagnosed as firmware problems.
Firmware and Bracket Check
Firmware revision recorded per card and bracket type confirmed — low-profile versus full-height. OEM-partner versions differ here, so we state what you are getting instead of assuming.
Report in the Box
Every unit ships with its per-machine diagnostic report and warranty. Full process: inspection guide.
Frequently Asked Questions
Why do Broadcom 57414 prices vary so much, from $25 to $75?
Because '57414' names a family, not one card. Within it there are single-port and dual-port parts and several OPN tail codes, and OEM-partner versions differ in bracket, airflow hardware and firmware branding. The tracked range for September 2026 ran $25 to $75, and the very bottom of that range is almost certainly a single-port part or a bare parts-pull rather than the dual-port 25GbE SFP28 card this page describes. What we sell and quote on this page is the dual-port card, which realistically sits in the $47–$75 band. Send us the OPN from the listing you are comparing against and we will tell you what it actually is.
How do I know I am getting the dual-port card and not a single-port variant?
Two things. First, the OPN: send it to us and we confirm the configuration before quoting — we do not quote off a marketplace title. Second, every unit we ship has its OPN read off the physical card and matched against your order as the first step of inspection, and the result is noted with the card. If you have an OPN and want it checked, or you need the dual-port card specifically and want us to source only that variant, say so and it goes on the order.
Broadcom 57414 or Mellanox ConnectX-4/ConnectX-5 for a 25G rollout?
Both do 25GbE dual-port SFP28 on PCIe 3.0 x8, and on a like-for-like dual-port basis the pricing is closer than the headline suggest. The 57414's advantage is volume and OEM familiarity: it is the card that already lives in Dell, HPE and Lenovo rack servers, so spares, brackets and partner firmware are everywhere, and the dual-port card undercuts a dual-port ConnectX-5 on price. The ConnectX-5's advantage is a cleaner, better-documented driver and firmware path and a very tight used price band ($99–$130, median ≈$119) with no variant confusion. Our rule of thumb: if you are filling OEM chassis and want lowest cost per port, the 57414 dual-port is the pick — verify the OPN. If you want one predictable card for a mixed fleet with RDMA workloads, pay the difference for the ConnectX-5. We stock both and will quote them side by side.
Is a BCM57414 card a genuine 25G card or a rebadged 10G part?
It is a genuine 25GbE part — the BCM57414 controller is a 25GbE design and the card supports 25GbE on SFP28. What people get confused about is speed negotiation, not the silicon: SFP28 cages also accept 10GbE SFP+ optics and the card will run at 10G if that is what you plug in or what your switch supports. So a '57414 running at 10G' is usually a cabling or switch issue rather than a mislabelled card. Tell us your switch model and target speed and we will confirm you can actually reach 25G.
Which server platforms take the Broadcom 57414?
It is a standard PCIe 3.0 x8 adapter and fits the mainstream 2U rack platforms — Dell PowerEdge R740xd and R750, HPE ProLiant DL380 Gen10, and Lenovo ThinkSystem equivalents — plus OEM-partner versions that were designed specifically for those chassis. Because partner OPNs differ in bracket and airflow hardware, tell us the exact server model and we will match the correct variant rather than send a generic card that fits the slot but not the chassis.
Are refurbished Broadcom NICs tested before shipping?
Yes. Every card gets its OPN read and matched to your order first — on this family that check matters more than any other — followed by per-port 25G link-up testing on both cages, an RDMA/RoCE bring-up test, a physical inspection of the SFP28 latches, and a firmware and bracket verification. Cards ship with the test result noted and carry a 1-year warranty.
