Refuse to work with Ryzen 1800x/x370

Pros: dunno, can't get it working on my board

Cons: device drivers report and error that the device can't turn on. I've tried multiple drivers and multiple slots on my board. Nothing.

Overall Review: Further investigation revealed that it doesn't play well with Ryzen chips. Seems like this would have been corrected by now as the AM4 platform has been out for a few years. Disappointing. I like Rosewill stuff.

Don't Buy

Pros: NONE

Cons: Not recognizable as USB 3 device by numerous USB 3 devices, including the BRIO camera several USB 3 'keys' and two different external USB 3 hard drives.

Overall Review: This product does not work as advertised. I have tried multiple drivers and it NEVER recognizes as a USB 3 device. Works fine as USB 2, but that is not what I bought it for.
I wanted it to give me USB 3.0 ports specifically to use a Logitech BRIO camera with Windows HELLO, but it is never recognized as a USB 3 device which is what HELLO requires.
After considerable 'playing around with this product, I find it is ineligible for return.
I will never buy Rosewill product again.

Disabled Sleep and all standby modes on Win10

Pros: None that I can vouch for

Cons: Caused my system to never go to sleep, hibernate or be able to shut down from start menu. I had to use power button to shutdown. Physically removed card and everything was back to normal. Windows 10 Pro, ASUS MB, latest update as of 07/12/19.

Overall Review: Maybe just my system but I did try power settings in Device Manager to make sure this card wasn't set to wake up system. When I click sleep, system willl go to sleep and in 2-3 seconds wake up again.

Works sometimes

Pros: Has never smoked or set my computer on fire.

Cons: Only boots about half the time. I had my peripherals plugged into this USB expansion and had to move them to my mother board USB ports so I can still use my computer when this card isn't working.

Overall Review: Would recommend finding another USB expansion card.

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.

Overall Review: 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.

Overall Review: 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.
