What is the main purpose of PCIe X1 slot?

PCIe x1 There is only one slot PCIe passageway . Even though there's only one PCIe passageway , but PCIe x1 Slots can be used for a variety of low-power applications PCIe Peripheral card . With the larger PCIe slot （ Such as PCIe x16 slot ） comparison ,PCIe x1 The slot is the smallest PCI Express slot , The throughput is the lowest . however ,PCIe x1 The card can be installed to all PCIe In the expansion slot , Include x4、x8 and x16 PCIe slot . Usually people underestimate their understanding of PCIe x1 Function of slot . This article will describe which peripheral expansion cards are connected to PCIe x1 slot .

PCIe X1 What is the main purpose of the slot ？

Even though PCIe x1 The slot has a PCIe passageway , But they are still useful , And in some cases , Use PCIe x1 Slots instead of larger slots （ Such as PCIe x16） To keep it optimized . Here are some pluggable PCIe x1 Slot expansion card .

1. Modem and network card

Can pass PCIe x1 Slot add a wired or wireless expansion card to the motherboard . Can be PCIe x1 WiFi Card or 1G PCIe Connect the Ethernet card to PCIe x1 slot . The motherboard usually has built-in Ethernet . however ,PCIe x1 Wi-Fi The card will Wi-Fi One of the ways to add a connection to your computer .PCIe x1 The slot can support all types of wireless network cards , Including the latest Wi-Fi 6 agreement . however , One PCIe x1 Slots can only support 1 Gigabit Ethernet or RJ45 Ethernet LAN（ LAN ） card ; about 10GbE Expand , Need one PCIe x4 slot .

2. Sound card

Usually a sound card is not required , Because most motherboards have built-in audio chipsets . however , Some enthusiasts or people who pay more attention to sound quality can PCIe x1 Install the sound card on the slot , To get higher sound quality and more accurate sound . stay PCIe x1 After installing the sound card in the slot , Computers can get better sound 、 More ports and better EMI shielding .

3. SATA Expansion card

When you want to add more to your computer SATA Hard disk drive , have access to PCIe x1 SATA Expansion card to add more SATA port . The third generation PCIe x1 The slot has 1Gbps The speed of data transmission , It can be done by SATA SSD（ Solid state disk ） or SATA HDD Store and process multiple SATA Expand . because SATA SSD The data transmission speed of is about 550 Mbps, and SATA HDD The data transmission speed of is about 150 Mbps, therefore PCIe x1 SATA Card processing is very suitable for NAS（ Network Attached Storage ） Multiple of the system SATA There will be no problem storing the drive .

4. USB Port expansion card

PCIe x1 It can also support USB Port expansion . therefore , If the computer needs more USB port , have access to USB PCIe x1 Add more cards to your computer USB 3.0 type A even to the extent that USB type C port . other I/O It can also be done through PCIe x1 Slot add , Just find something with PCIe x1 Of overall dimensions I/O Expansion card is enough .

5. TV tuner card

PCIe x1 Another use of the slot is the TV tuner card . Use PCIe x1 TV card , You can let the device receive TV signals directly on the computer , Turn the computer into a TV . Some cards even allow your computer to record live TV programs directly from the cable , For later viewing .

6. Video capture card

The video capture card enables the computer to receive data from cameras or other external devices （ Like a game console 、 TV or DVD player ） Any video source , And convert these video signals into digital data that can be stored on the computer . These converted data can be streamed or saved in real time for post editing . Usually ,FHD Video capture uses PCIe x1 Expansion card , And more HD 4K The acquisition card needs at least PCIe x4 Expand slots to handle bandwidth requirements .

7. PCIe Lift card

If the motherboard needs more PCIe slot , have access to PCIe The adapter card , Also known as separator . It should be noted that ,PCIe The adapter card just increases the number of slots , and PCIe The bandwidth will remain the same , Evenly distributed on the adapter card PCIe In slot . therefore , There are four PCIe x1 The slot is connected to a PCIe x1 The adapter card for the slot will have a quarter of the capacity on each slot PCIe x1 bandwidth .
