Gigabit PCI-Express desktop adapter

The Intel EXPI9301CT is a single-port Gigabit network card for PCI-Express slots. It provides a wired 10/100/1000 Mbps connection through one RJ45 jack. The plug-in card fits standard desktop chassis dimensions of 4.70 by 4.73 by 2.18 inches.

Suitable for wired desktop upgrades.

This adapter suits users adding a single Gigabit Ethernet link to a desktop PC with a free PCI-Express slot. It operates from 0 to 55 °C at up to 90 % non-condensing humidity at 35 °C. Builders needing multiple ports, fibre connectivity, or a low-profile bracket should look at other options.

Single RJ45 port at 10/100/1000 Mbps

The card delivers one copper RJ45 port running at 10, 100 or 1000 Mbps over twisted-pair cabling. This single-port, copper interface is the specification that determines whether the adapter matches the network infrastructure.

Questions about this item

Will the single RJ-45 port need replacement after heavy use?

The port is rated for standard Ethernet durability; no user-replaceable parts are listed for this adapter.

What thermal limit appears first during continuous 1000 Mbps operation?

The operating ceiling is 55 °C; sustained loads that push the card beyond this temperature will trigger throttling or shutdown.

How much heat and power does the card produce when running all day at gigabit speeds?

Typical draw is under 5 W and the card stays within the 0–55 °C range with passive cooling inside a normal desktop chassis.
