In the digital age, our computing needs are constantly increasing, and the number of interfaces on computers is often one of the limiting factors. In addition, on many hosts and motherboards, the number of various USB interfaces and the transmission speed cannot meet the needs of today's peripheral expansion and data transmission.
In order to solve this series of problems, PCI-E to USB expansion cards came into being. Not only do these cards provide an additional USB port for PCs, but they also offer satisfactory performance in terms of speed and flexibility. Of course, in addition to PCI-E to USB expansion cards, some PCI-E expansion cards also contain M2 ports, SATA ports, PS2 ports, and other old-fashioned ports, etc.
This issue takes stock of the four PCI-E to USB expansion cards currently on sale, which are well-known and have relatively high sales volume, in no particular order, in alphabetical order.
EB-Link 8-port USB32 The expansion card adopts NECD720201 and VIA VL805 dual chips, which greatly improves compatibility and stable operation. The gold finger is thickened, the contact is more reliable, and the hardware contact failure is reduced. Independent power supply, no additional power connection is required.
The expansion card can be compatible with PCI-E X1 X4 X8 X16 slots, and can be expanded with six USB-A ports and two USB-C ports, supporting two types of devices to run at the same time, with a theoretical rate of up to 5Gbps, easily expanding mouse keyboards, printers, mobile hard disks, audio, headphones and other devices.
The Capricorn PCL-E X4 to 4-port Type-C expansion card is equipped with a high-performance main control chip ASM3142, which works independently and does not occupy computer CPU resources. The use of high-quality PCB board, high temperature resistance, cold resistance, long-term use without deformation, so as to ensure long-term stability. Thickened gold-plated gold fingers ensure a secure connection to the motherboard slot to ensure data transmission integrity and stable operation. It is also independently powered and does not require additional power connection.
The expansion card is compatible with motherboards with PCI-E x4 x8 x16 slots, making it plug-and-play and convenient. It can be expanded with 4 USB-C interfaces, of which three USB-C share 10Gbps bandwidth, and the other C port has an exclusive 10Gbps bandwidth, and the bus bandwidth reaches 20Gbps, which can easily meet the needs of accessories expansion and data transmission.
Orrick PCI-E to Type-C expansion card is equipped with high-performance main control chip ASM3242, which works independently and does not occupy computer CPU resources. Thickened gold-plated gold fingers increase the conductivity of the contact point with the card slot to ensure stable transmission. With a 15pin power supply interface, it provides more adequate power protection.
The expansion card is compatible with motherboards with PCI-E x4 x8 x16 slots, making it plug-and-play and convenient. It can expand a USB-C interface with a transmission bandwidth of 20Gbps, and the official measurement is 1700+ MB s, which can realize fast data interaction, and truly read files in seconds with less waiting. Easily meet the needs of accessories expansion, data transmission and so on.
Greenlink PCI-E to 4-port USB3The 0 expansion card is equipped with a high-performance chip and a 15-pin power supply interface to provide more adequate power protection. The thickened gold-plated contacts are stable in plugging and unplugging, and the contact is reliable.
Greenlink PCI-E to 4-port USB3The 0 expansion card supports standard ATX chassis, is compatible with PCI-EX1 x4 x8 x16 slots, and expands four USB-A ports with a theoretical rate of up to 5Gbps. Mainstream operating systems can be installed and used directly without a driver.
In terms of extended interfaces and transfer rates, the four PCI-E expansion cards are different. EB-Link expands a wide range of interfaces, including a total of eight USB-C ports in 2C6A, supporting 5Gbps bandwidth. The second is the expansion card of Greenlink and Capricorn, the expansion card of Greenlink comes with 4 USB-A ports, and also supports 5Gbps transmission.
Capricorn's expansion card comes with 4 USB-C, supports up to 10Gbps high-speed transmission in a single port, and has a total bandwidth of 20Gbps. Finally, Orrick's expansion card, although it only contains a USB-C interface, but the transmission rate is also the highest among the four, and a single port can achieve high-speed transmission of 20Gbps bandwidth.
In terms of overall materials, as well-known accessories manufacturers, Greenlink and Orrick do not need to worry about workmanship and materials. EB-Link and Capricorn also use the main control chip of well-known brands, and have good sales and reputation on the e-commerce platform, so there is no need to worry about workmanship and after-sales problems. Users can choose PCI-E expansion cards with corresponding interfaces and different speeds according to their needs.
