Product Description

Product Description

The PCIUSB3S4 4-Port PCI to USB 3.0 Card enables legacy PCI slots to support the SuperSpeed USB 3.0 standard, which is capable of data transfer rates up to 5 Gbps. Using USB 3.0 devices with this card will increase data transfer rates with up to 1.3 Gbps of available bandwidth (PCI bus limit) – more than doubling performance compared to a USB 2.0 connection. Note: Some newer PCs may use a PCIe to PCI bridge which can cause unexpected compatibility issues with this product. This versatile USB 3.0 adapter includes an optional SATA power connector which allows each USB port to deliver up to 900mA of power to connected USB 3.0 devices – suitable for even the most power hungry devices. A perfect solution for older PCI-based systems or computers with only PCI expansion slots remaining, the card allows those systems to stay relevant and up-to-date with the latest USB technology. The card is also backward compatible with USB 2.0 and 1.x devices, so it will not only work with any future USB 3.0 devices, but will also support older devices.

    I had a vintage 2005 desktop with legacy equipment, that had trouble supporting USB 2, and is off the network. Every day, syncing 2 GB of data to a USB stick took 15 minutes at the end of the working day. Now, with this card, I can use my USB 3 drive instead of the stick, and it only takes 50 seconds! The card has paid for itself in two days!!! Also, I love the extra power connection to a SATA power cable. My desktop has only 1 hard drive, but there are two hard drive bays and two SATA connections. Using one of them for the USB card really helps – my external drive exceeds power limits on a lot of computers (it came with a Y-cable, but it often has trouble with power even from two USB ports) – and with this extra power boost it works off of 1 USB without any problems!!! Another unexpected bonus: good power circuit protection. The first USB cable I tried on this card had a power short (what are the chances of that!?) – and I got a lot of system warnings “USB accessory is exceeding power limits. Please reset”, constantly… I thought I had a bad driver, but then there was smoke coming out of the other end of the USB cable. The card survived that ordeal without any damage, it seems. Great, awesome product!!! Works perfectly with my Windows XP SP3 legacy computer from 2005.

    Used in old Foxxconn LGA775 motherboard with only one PCI-e socket, which was already being used by graphics card. Took a chance and am very happy. Was able to transfer a 6GB movie ( Blade Runner 2049) from external HDD to documents library in one minute 15 seconds vs 4 minutes 20 seconds with USB 2.0. Just as fast as my laptop with built in USB 3.0. More expensive than I wanted but real world speed is very good. I know that PCI is limited in bus transfer rate, but, this thing saved the day. I highly recommend. Drivers updated automatically on startup!

    I bought to add USB 3.0 to my old Gateway LX6810-01 which I bought new in 2009 and still use as a primary machine. It is stock except for an upgraded Corsair 750W power supply and Sandisk 1 TB SSD. That leaves it with an available PCI slot, which this card fit. However, the case interfered ever so slightly with the USB ports (because they’re vertical not horizontal as in the 2-port version of this card) but with some persistence, I was able to plug a USB cable into each port. Also, I received Error Code 31 in Device Manager which meant the drivers were loaded but due to the enabled Windows 10 Fast Startup, it took me some time and internet searching to find out I just needed to perform a restart to make it work. That did the trick. It otherwise works beautifully and I was able to take full advantage of the new 802.11ax standard with a just-released USB Wi-Fi 6 adapter and my ISP’s Wi-Fi 6 gateway.

    The CD they provided in the box did not contain the proper setup file on the rood directory.Lots of setup file buried in other folders, but I couldn’t find any that worked.Fortunately their website had the correct setup.exe file which worked fine.

    I heard 3.0 was a faster download and anything faster is better. What a easy add for a bank of 3.0 USB ports . You can’t be afraid to open the computer up, suck the cobwebs out with a vacuum (unplug the thing first) Most computers have a extra SATA slot to power this thing. Great add

    Installation is straight forward. All you need is an available PCI slot on your mainboard, and optionally an available SATA cable (and port) to connect to the adapter for more power if you find that you need it. I have an available SATA port, but I tested the card without the SATA connection, and all is working well for me so I did not bother connecting it. I have an external USB3 SSD drive, and now I can access it about as fast as I can my internal SSD drive. I am also using a USB3 WiFi adapter that supports 802.11ac, and now downloads get up to about 250 Mbps on my ATT Fiber 300 service. I could not be happier! I would recommend this adapter to anyone who does not have but wants USB3 support on their computer. The connection speed of USB3 over USB2 is an order of magnitude faster!

    Product worked good for me. Would buy again.

    I bought this PCI USB 4 x 3.0 connector card and received it on 2020-10-10. After usual external checking, I executed installation on an MSI C770-C45 board + Win10; an extra cable Molex 8981 to SATA was needed from my personal stock, and by about 15 minutes later installed it was.It is working perfectly, even when my PCI slot has one gap and the card has two; beware of this issue whoever wants to buy the card, specially to upgrade/extend life of old motherboards, for I did it on my own risk. Fortunately, it worked! Let us see how much the card will endure; I hope it hold until around 2030 EC…

    It works

    I have an older desktop that I picked up a few months ago for around $70. It is a Dell OptiPlex 780 SFF (Small Form Factor). This computer was GREAT for streaming video and general administrative stuff, but I wanted to see what I could get out of it. Long story short, I wanted dual displays, which meant that I had to buy a graphics card (Geforce 1050 2G, great choice also). After buying a few games, my small 320G HD was filling up fast. After doing some research, I found that the most common interface between an external HD and your PC is USB 3.0. This dinosaur definitely did not have that hub, and I had already used my only PCI-16e slot on my GPU. I bought this card, installed it in 5 minutes, and seamlessly hooked up a 2TB external Fantom Drive which works to perfection.My only complaint is the driver CD that comes with the card. The driver disk does not work well on Windows 10. However, if you visit the manufacturer’s site, the driver installs flawlessly. I highly recommend this card for anyone wanting to bring some new life to an old computer
