USB PCIe Card, 4 Port USB 3.0 to PCI Express Card Expansion card, PCI-E to USB 3.0 4 Port Hub Controller Adapter, Rosewill RC-508 PCI-E to USB 3.0 Add On card

Card is easy to install but before you purchase check your motherboard for an open F USB 2.0 head to power the card. Max WIFI speed increased from 58 Mbps per sec. to 144 plus Mbps transmit/receive, a substantial increase. Blue tooth has increase range and I can now walk around my office without losing connection to my headset. What a pleasure that is not being tied to my desk while listening to music and videos. I was disappointed that the provided drivers were out of date and had to search for updated drivers. No link for driver updates were provided. Other than this issue, the card is a definite improvement over the AC 7260 half size wifi/bluetooth 2 x 2 card it replaced. I'm very satisfied with this purchase, the price and ease of installation and no more dropped connection frustrations.

Works in my Linux distro, no setup fuss, just plug it in and fire up the system. My 10 year old BIOS apparently doesn't support booting from PCI express (was hoping to boot a live distro through this card, but I can still boot via onboard USB 2.0).

I bought this card because we recently got an Oculus Rift and the audio intermittently would stop working. I was almost ready to return the rift. I read an article that said it could be an issue with the USB 3 on the motherboard and to try an add-on card. I figured for less than $20 it was worth a shot. I stuck this card in a slot of the Z77 motherboard, plugged the Rift’s USB into it and powered on the PC. So far, so good. The audio has been working correctly. I didn’t install any drivers (Windows 10 PC) and I didn’t plug in the power connector on the card. It is working great. It’s nice having a few extra USB ports as well. Definitely worth the money.

Here's a quick review to explain my experiences installing this card in February 2017: I was expecting a quick, 5-minute install but it had been awhile since I got inside my machine. None of the power connectors were long enough to reach the card. This card is only a few inches long (it's shorter than it looks in the photo), it's not like a video card that will be closer to the back of your motherboard. The small size is actually a good thing for being in cramped spaces, but you might want to see if your power cables are long enough before ordering, and if not, buy an extension for a few dollars if you don't already have one. I was able to work around this issue by rearranging my internal drives so one was mounted closer to this card (and therefore, so was it's cable's extra molex connector), so the 5-minute install took longer than I thought. The next problem was that Avast (virus software) reported a virus in one of the files on the installation CD and wouldn't run the installation program. It could have been a false positive, but it had never happened to me before with any hardware installation CD over the last several decades, so I was reluctant to turn off my virus software to install a $16 card. The workaround was to find and download the drivers on the internet. Avast had no problem with the downloaded drivers. The drivers on the internet looked like they were for a different brand card (it might have been identifying the chipset) so I wasn't 100% sure of them either, and after installing the drivers the card didn't work. But after rebooting everything has been fine. The card has been working fine and for $16 delivered the value can't be beat. I bought this to speed up an external hard drive that was getting it's speed throttled by the USB 2.0 connector on my computer. After upgrading to this USB 3.0 card the external hard drive's speed more than doubled. In fact, it runs much faster than my internal hard drive. Since vendors sometimes modify the products in these sales pages, to be clear this review was for the following: Rosewill PCI-E to USB 3.0 4-Port PCI Express Expansion Card (PCIe Card), 4 USB 3.0 Ports, Super Speed Up to 5Gbps, with 4 pin Male Molex Power Connector & Renesas Chipset

This is just the ticket for a USB 3.0 Audio Interface running Windows 7. The Renesas chipset makes the interface utility run flawlessly. Stopped the pops and clicks found inherent in other cards of this type. In a recording situation these noises need to be held in check. The drivers installed from the disk set up and ran perfectly. No need to search for drivers over the net. I have yet to hook up the additional 4 pin power cord but I will do so forthcoming but as of yet hasn't affected performance and may only be needed in devices that don't support their own powering. If you are on Windows 7 and need to power a USB 3.0 audio device this PCIe 2.0 USB 3.0 card is the ticket. Early Windows 7 Desktops did not support USB 3.0. These type of cards will let you get up to speed.

I bought this to put in my Plex server so I could connect an external Sans Digital raid box. The card was auto detected by Windows Server Essentials 2012R2 and loaded with no problems. Attached the external array and it was detected and showed up to the OS with no problems as well. 20 months later, the card died with no warning, no USB 3.0 drives attached to it are seen by the OS even after a complete server power down and restart. Connect the same USB drives to a different workstation and they are detected immediately. I have always had very good luck with Rosewill products, some are still going strong 5+ years after install, but this one failed me. I had bought the Rosewill 4-port USB 3.0 to replace an Inateck 4-port USB 3.0 card that also died unexpectedly less than 6 months after install. At this point, It doesn't seem like any of the USB 3.0 add on cards are really 24x7 "server ready". I am sure the servers built in USB 2.0 would work fine, but...... I am going to try a Startek PCIE E-Sata card to replace this USB card as the Sans Digital enclosure is dual ported, Thanks Sans Digital....... Hopefully it will last longer.

The Rosewill USB 3.0 card is the only one that has kept working post Windows 10 update 1803 June amendments. Whether it is luck or good planning/execution, the Rosewill's Renesas chip and drivers are compatible with the latest Windows, whereas cards of mine from Syba and Inatech - which have Fresco chips and drivers, fail miserably to continue to operate at USB 3.0 speeds. As my network's large backup disks are attached via USB 3.0, to have them operating at the far lower speeds is not feasible. So yay again for Rosewill, whose other products seem to adhere to a high standard too.

Update 4-45-18 Upgraded to Windows 10 and it does no longer work. I eventually gave up and took it out. I tried everything I knew for 2 weeks. Tech support sent me a cut and paste reply never having read the question. A request for more help has not gotten a reply. Not easy to install in Windows 7 either with the windows drivers or the drivers on the disc. Support section of the website offers no support at all, only warranty registration. I am sure that there is a way to install it but no way to find out what it is. I may need to return and try another brand. If I find some method of installation from a third party I will post it here. Update: Found a firmware installer and driver on the site under downloads but it did not work. The device appeared under "other devices" in the manager which is strange. Tried updating windows to see if new drivers there but no luck. Update: Got it working. Increased stars to 3. After doing the above I removed all software that was on the disc and the website from the PC. I Uninstalled the device. I shut down the PC. I removed the card (which had been securely installed by the way) and then put it back. I restarted the PC and then used the firmware checker from the Downloads section of the site to verify that it had the newest firmware. I installed the software installer from the site which did install it and this tile it went into USB devices where it belonged and installed. It works well, just a beast to install. By the way I built this 8tb, quad core PC myself and do electronics repair as a hobby so if it ain't easy for me....... I love the smell of new hardware heating up for the first time
