Description

The 4-port USB 3.0 PCI express card (with SATA Power) adds 4 external USB 3.0 ports to any PCI Express-enabled computer system with support for data rates up to 5 Gbps, while remaining backward compatible with USB 2.0 / 1.x devices. Enhanced with UASP support (USB Attached SCSI Protocol), this SuperSpeed USB 3.0 PCI express card performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. The 4-port USB 3.1 PCIe card uses a "stacked" port layout that places the ports one on top of the other, enabling all four USB 3.0 ports to be external facing, while still allowing the card to fit into a small form factor/low profile computer system using the included low profile bracket. Plus, with a built-in SATA power connector, each USB port can provide up to 900mA of power to devices that draw power from a host bus connection (500mA for USB 2.0) by connecting to your computer power supply. This USB 3.0 expansion card is backed by a StarTech..

    • Finally a USB3 Card that really Performs!
Size: 4 Ext Style: PCI Express
Review Image by WildBill
Overall I went through a few USB3 cards and they just barely beat USB2 performance, when they worked at all. So it was a great pleasure when this just plugged in and worked after loading the drivers, which come supplied on a CD. This board is really fast and lets you get the most out of your USB3 drives, especially external SSD drives, they really scream on this interface card. Hard disks or SSD is about the only thing that will benefit from USB3, most other things are slower, like a keyboard or mouse, even a TV USB box does not even tax USB2, but no doubt you will get a major boost in performance if you have USB3 drives currently plugged into USB2 ports. Overall this is a great product that does exactly what is says it will do. I would not hesitate to suggest this to a friend and am very happy with this purchase. This cost about twice as much as many of them but well worth it, it works. Hardware Installation Rating = 5 The physical install is very easy, open your PC, find an empty slot and plug it in. You can optionally provide the card additional power by plugging in a spare SATA power cord in your PC. If you do not have a SATA type connection or no spare power cords in your PC you can get one from Amazon for under 10 bucks. (Older PC tend to have 4 pin Molex power connectors, if that is your case you can get a Molex to SATA adaptor here for under 10 bucks. The good news is that power cable is not required for the board to work unlike most of them, and if everything you plan to plug into it is powered itself then there is no need for the internal power. If you do plan to use the USB3 ports to power things you should hook up the extra power. Software Installation Rating = 5 As easy as it gets, pop in the supplied CD and run set-up, reboot, and that is it. The CD I got had the most current drivers which was nice. Performance Rating = 5 The real test was benchmarking it, with my original USB3 card I could not get more than about 90MB/s on a file copy, with this I am hitting 240 - 270MB/s, benchmarks and my USB3 SSD drive is insanely fast. With this card all of my USB3 drives are about twice as fast as with my old USB3 card. (the old one came with my PC and had an older chipset, it was faster than USB2 but not a lot.) Note: if you have USB2 drives this is not going to make them go faster unless you have an underperforming USB interface, which is unlikely) However if you have been using USB3 devices with USB2 you will be blown away how much faster they go. I also tried some old USB2 drives and they worked perfectly, albeit slower by nature than a USB3 drive, but it hit full USB2 speeds with USB2 drives. My system: HP Pavilion H8-1090t / Intel i7-990 Hex Core / 24GB RAM / 1xSSD internal SATA(500GB) / 2xSATA internal hard drives / 2xUSB3 2TB external drives (Seagate) / 1xUSB3 SSD (U32 Shadow) ... show more

Installing in a Dell Optiplex 990 SFF with 32GB DDR3 RAM Added. Its to replace a low budget one I bought recently with a Realtech Driver that survived only 6 days running Debian Forky Linux. I am using SATA Power from the onboard OEM PSU. I would never buy anything but StarTech for an older PC hereon out. The few more Dollars is a great investment for the long haul. Shipping came a day later due to a delay. Its January 4 when Ordered Post Holidays so was a bumpy shipping. Amazon apologized and got it to me the very next following day than promised originally. No biggie. Otherwise Shipping would have been swift! ... show more

    • Lots of ports in a little space
Size: 4 Ext Style: PCI Express
This is for the 4 external port version. Added this to a small server running Server 2012R2. The Renesas chipset drivers were already included in the OS, so it was true plug-and-play. This card was added for fast transfers to external backup drives, and did not disappoint. This was one of only a few solutions for fitting four parts in a low-profile board space. Some applications with dongles or thumb drives might have an issue with the tight spacing between ports, but my various cables plugged in without any problems. Transfers to the drives now take place at the maximum speed of the actual SATA drives inside the enclosures, shaving lots of time from a 2-3TB backup. ... show more

    • If I wasn't lazy, I'd return it. Don't bother with this one.
Size: 4 Ext Style: PCI Express
Figures it would take a negative experience for me to want to write a review. Firstly, the fact that the driver comes on a CD is ridiculous in 2026. I installed the USB port using an previously used SATA cable I had laying around. Given that I have a 1000W power supply and could just download the driver online, I expected there to be no issues. There were issues. From the moment I found the Renasas driver online, nothing went well. The USB card did not enumerate any of my peripherals no matter what I did. I confirmed that it was receiving power, so once it was installed in my tower, the issue had to be software-related. I literally downloaded a Media version of Win10 to create an ISO & did a fresh install of Win10 (kept apps and such), and even that didn't fix the issue of any of the USB ports recognizing my peripherals. Using a mobo from 2019 shouldn't be an issue and everything about my experience trying to use this card was an absolute nightmare. Getting the firmware was also useless and every solution referenced something complicated and technical for the average PC user. I literally wasted an entire day fighting in Device Manager and the $40 price for this trash is a travesty for a mostly unsupported USB card in 2026. ... show more

    • PCIe x1 StarTech 3.0 USB board
Size: 4 Ext Style: PCI Express
Installed this PCIe board in my HP Win7/64 system, installed the software, and it worked beautifully - for exactly 1 day. Now my system doesn't see the hard drives in the USB ports, nor does the board appear in Device Manager. Tried everything to get it back, but no dice. Looks like a defective board. Only getting one star because otherwise I couldn't post this. Grrrr! Tried tech support, but of course nobody home in the chat for the weekend. I can report the hard drives back to the 2.0 USBs, but will have to take the darned computer apart again to remove the bad board.On top of it, now my HP keeps installing and removing my hard drives, mouse and keyboard. Put everything back on 2.0; will see if it settles down. This board isn't cheap; I expected it to function as advertised. UPDATE! Contacted StarTech, they advised reseating the board in a different PCIe slot. I had moved out a smaller board to accommodate the 3.0 board. So took it apart again, put small board back where it was, did minor surgery on the case back, removing a flimsy piece of aluminum between the 3.0 and case back and reinstalled everything. 3.0 board now works perfectly, sees hard drives, etc. and the system has settled down to usual condition. The 3.0 is fast, well worth the money. The flimsy aluminum CPU piece, slightly heavier than foil, was probably either a static buffer or some kind of heat sink, but prevented the usb connector from seating into the board's slots properly by adding just enough of an additional layer of material. Update 10-21-15 All working just fine now, no problem whatsoever with board. Earlier problems were with my PC configuration totally, as the board has been working just fine with no glitches for months now. And Tech Support was very helpful. 2018 UPDATE: The board stopped working again, about two weeks after last update review. And I gave up. It's still in the PC, but I just tried it again and no life evident. This board was expensive, and the performance was definitely not what was advertised. Very disappointed in this product. ... show more

I bought this for my EVGA X58 SLI Micro system board running Win10 Pro. Plugged into a PCIe II slot, I get between 2 and 2.5 X the speed of the USB2 ports.

    • Got REALLY tired of cheap cards. Just get this one!
Size: 4 Ext Style: PCI Express
I tried probably 3 "affordable" PCI express cards for my desktop to expand my USB ports as my ports on my motherboard felt like they were overloaded and wanted to disconnect randomly. Extremely annoying to the point where I decided I needed a dedicated and powered card. After dealing with multiple cheap crappy cards. I did what I should have done from the beginning and got a StarTech card. Works absolutely flawless and solved my cutting out issues with plenty of USB power and stability for connections. I cannot recommend StarTech cards enough. I have 2 in my case as the other card from them is a dedicated USB-C Card for VR. That card is also amazing. ... show more
