HP 546SFP Mellanox ConnectX-3 Pro Dual Port 10Gb SFP+ Network Card (Open Box)

This is an HP 546SFP, which is actually a Mellanox ConnectX-3 Pro card in disguise.

It’s a dual port 10Gb SFP+ network interface card.

This specific one is listed as open box—so it’s in excellent condition, like new, but might not be in the sealed retail packaging.

It’s got the original accessories with it though.

The chipset is the MCX312B-XCCT, which is super solid for high-speed networking, low latency, all that good stuff.

If you’re building a home lab or need fast transfers between servers, this is a killer deal.

It’s made by Mellanox (which is now NVIDIA) and sold under the HP brand.

A great way to get into 10 gig networking without spending a fortune.
