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 I was disappointed that the provided drivers were out of date and had to search for updated drivers.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.

It was plug n play on my motherboard. Nothing to complain other than should have read better: I needed 4 dedicated controllers on my card. This one has 1. Doesn't make it bad, just not suitable for my specific need. Still have 4 extra USB connections yay!

Good

Parfait.

Works grate!

Installed, including power connector from mothrboard. Audio distorted with constant dropouts when unit is used to send signal to external DAC. When I unplugged USB cable from the Rosewill card and used a free USB port on my original motherboard, the problems went away. This will be getting pulled from the PC and thrown in the garbage.
