DON'T FORGET TO CONNECT A 4-PIN POWER LEAD TO THIS CARD!

Pros: You MUST connect a 4-pin Molex power lead to this card from your PC's power supply. USB 3.0 delivers more power for the devices you plug in, and that power comes from connecting a power lead to the little 4-pin socket on the rear edge of the Rosewill RC-508 (or any other USB 3.0 add-on card).

A number of reviews have said they plugged one or more items or devices into the USB 3.0 ports on this card and it didn't work, or "it died", or similar. I strongly suspect these users simply forgot to connect that power lead from their power supply to the 4-pin socket on the card.

You need this speed because almost everything you buy now has USB 3.0 capability, and you DON"T want to cripple your devices by using the older, much slower USB 2.0. (The only exception is that most webcams don't work any better on 3.0, unless you get a 4K webcam).

Many PCs come with only a couple of USB 3.0 ports so this card quickly expands that with 4 extra ports.

Cons: None at the price.

If you need the absolute fastest USB port you can buy a USB 3.1 Gen.II add-on card at higher cost and with only 2 ports. That would be useful for connecting a fast, external SSD for serious creative/editing work.

But, for most users, a 4-port USB 3.0 card will do fine.

Other Thoughts: Our older PC still works great and we don't intend to replace it anytime soon. Since it only has USB 2.0 ports we added the USB 3.0 4-port card. It worked right away and the speed is 4 to 8 times faster depending on what device we plug in.

Perfect!

Pros: Absolutely no problem in installing.
Works great and is fast!

Cons: None. For the record, contrary to what I have read in a review, the necessary drivers ARE in the Rosewill site.

Other Thoughts: I recently purchased a refurbed HP Compaq 6000 Pro from Newegg. It has 10 USB 2.0 ports but no USB 3.0 ports. I purchased a Rosewill USB 3.0 hard drive enclosure for this computer so this card solves the problem. Backups are taking just 3 minutes now.

Just added another one.
Very nice product.

Ruined two webcams, LEDs in a mouse, and almost burnt out a StreamDeck

Pros: Literally None

Cons: After installation I tested my mouse. I tried to rearrange cabling and plugged in two webcams. Immediately they stopped working. After troubleshooting they are both dead. After about 10 minutes I noticed none of the LEDs in the mouse were working. I also attached a streamdeck to the device. I touched to the deck to test it and noticed it was literally too hot to handle. Luckily that wasn't fried as well.

Do Not Buy for Ryzen

Pros: It was cheap.

Cons: Does not work with my system. Contacted Rosewill and they RMA'd through Newegg. Replacement doesn't work either.

Other Thoughts: Apparently they have issues with Ryzen builds, so if you are Team Red, grab something else. If you are Team Blue, might be a higher review, but I'm rating it for my system, so it gets 1.

Possibly working on AMD Motherboard

Pros: -Adds USB 3.0 ports

Cons: -Difficult to get working on AMD systems
-Requires 4 pin power

Other Thoughts: I purchased this to give myself extra USB ports for my Oculus rift system. Initially out of the box, the card wasn't being recognized by my PC. It appears many other reviewers have the same issue with Windows 10 and AMD systems.

Current working solution:
I was able to get it working (so far) by removing the card while the PC is running, and plugging it back in. Windows then recognized the card, and pulled up the default driver.(Renesas USB 3.0 eXtensible Host controller). I did not install the device drivers from the CD or the website. I have rebooted the PC a couple times and it still appears to be working, so I hope that this sticks, and maybe the solution works for someone else too.

Previous troubleshooting:
-Tried downloading drivers from the Rosewill website... didn't work.
-Tried switching the PCI slot the card was plugged into (while PC was shut down)... didn't work.
-Tried disabling and re-enabling card through the Device Manager... didn't work.
