    Are there any usb 3 cards to that dont require extra power to run at usb3. I bought a caldigit usb3 card and when I received it I noticed that it has a power connector on it. Called OWC and they said basically you will need to get power from the psu in order to run it at usb3 for things like hard drives but as far as flash or card readers it should be fine.

    They said getting power routed to the card from the psu is basically a pain.

    Hello, I got a Caldigit USB 3.0 combo card with eSata ports also at OWC

    I just installed the card and the driver from the CD that came with it. I did not anymore connect the card to the Mac Pro's PSU. Unless I missed it, I did not seem to see a power connector. The reviews by users also did not mention about connecting the card to a PSU. You can also check out the Rocket USB 3.0 card as I heard it's also a good card. There is another brand, Orico USB 3.0 card, a popular card too. This one needs to be connected to a PSU as I can see a power connector at the back of the card .

    USB3

    Here is the one I got. Look at the top of the back of the card. It is like a small 5 pin power connector. I might return this because I dont feel like routing cables.

    Yep I see the white power connector at the backend. I also find routing of cables to be a bit complicated. :)

    If you want a USB 3.0 card that is designed for storage devices / RAID, then have a look at the one in my signature. It works great for me, requires no additional power. It won't work with hubs though, it is the hub.

    Also, if storage devices are your goal, this card has a separate controller for each of the 4 channels. This means it is particularly fast compared to any of the others. It doesn't have to share bandwidth and it won't slow down. In fact, it has a very nice RAID function that just flies. You won't find another card this fast for storage devices, but it's rather expensive.

    The Orico PFU3-2P does not require supplemental power to operate. I have tested this with flash drives and 3.5" external drives that have their own power supplies.

    It might be possible that there is insufficient power for a high-current device such as trying to charge an iPad off of it. In that case, I'd ensure there is a powered USB 3.0 hub in between the card and the device, or use the MP's built-in ports.

    The main advantages of the Orico are that it is very inexpensive (about $18-$25) and it uses native drivers built into OS X, so there is no dependance on downloading third party drivers from websites and less worry about future OS support.

    The main disadvantage is that both ports on the card are connected to the same controller, so hooking up two drives and using them simultaneously really slows things down.

    I personally use the PFU3-2P and it works well for my purposes. I use it for USB 3.0 flash drives and USB 3.0 External Desktop drives. It also works with the USB 3.0 hub built into my Dell Ultrasharp.

    There are some other things you should be aware of:

    (1) While transferring date, USB 3.0 can interfere badly with Bluetooth. This is a known problem in the industry and is not limited to just Mac Pros with add-in cards. The Mac Pro is affected more than most because its Bluetooth reception is notoriously weak to begin with. If you use Bluetooth devices, be aware you might lose reception, which is fixed by either adding an external antenna or adding a USB Bluetooth dongle.

    (2) Some of the more expensive cards are for "storage devices" only and won't connect to other types of USB 3.0 devices. People discovered this when they tried to add a hub, couldn't, and were told by support that the cards were for storage devices only. Sorry, cannot remember which one has this problem.

    (3) The Orico card will work with many hubs, but not all hubs. There is a thread that toward the end has some compatible hubs listed.

    What hardware (Pro Model) and OS version are you running? That's an older Generation card, probably not what you are looking for. You likely need the same card I'm rocking.

    It's an awesome card, you just have to get the one that is made for your generation of hardware and OS. The 1144CM is the one I use, it also works well with Mavericks.

    The reason some people think low of it is because some of their older cards became incompatible with newer machines and OS's. The card is fantastic... Just do your research and get the one intended for your machine.

    If you want a general purpose card, I would definitely recommend the The Orico PFU3-2P that ActionableMango pointed out.

    Those are your top two choices bar none IMO.

    Well its a 4,1 -----> 5,1 upgraded .. running mountain lion and soon to run mavericks.

    I am not looking to run hard drives off it really. Basically I might connect a usb 3 portable hard drive to load stuff or transfer something .. but no serious storage. Mainly going to use it for flash drives, card reader for my dslr. I just want a few ports .. 4 would be amazing. But I want full speed.

    Then the ORICO card is definitely the one you want, but you can only have full speed on one device at a time. All the cards PC/Mac are like that except the HighPoint (which doesn't seem suited to your needs either).

    The HighPoint will work for the Flash Drives & card reader (at least mine does), and can't speak for a camera though. It might work if it sees it as a storage device. I don't have a DSLR so I can't test that for you.

    That's a 2 Port card. It's the same one I mentioned in the link, just from a provider that is charging $5 more. I would probably get that one and connect it to a powered hub for extra ports. Just remember that they are all sharing bandwidth.

    It doesn't need power for low draw devices.

    i got the orico 4port powered from the second optical sata..its really a good card no kernal panics or software to install because its all native..installation is tricky tho because you have to disassemble a molex head and thread them through a corner opening in the opitcal bay down to the pci slots...the caldigit one needs drivers and i heard some people on here having massive panics with that card

    Thanks. I may also try to save up for a RocketU 1144CM USB 3.0 and give it a try. :)

    I would have a second though about USB3.0.
    I tested driver-less eSATA (6Gb) PCIe Gen2. vs USB3.0 (NEC/AsMedia/Eltron... you name it)

    eSATA is out shine USB3.0

    I also have an Orico 4 port USB 3 card. I used a 4-pin Molex to SATA power cable to power it.

    The card has worked very well. however, I do have a minor gripe, the plate that covers the PCI-e slot didn't fit perfectly and took a bit of finagling before I could screw in the locking plate.

    The card you linked to in your post above (from Amazon) seems like it's just what you're looking for. You probably won't need any power connectors and the drivers are plug-n-play. At that price you can hardly go wrong. I don't even need one, but I'm going to order myself one of these (from the $15 supplier).

    Alright well I just ordered that 4 port usb3 card .. for 19.99 i guess i cant go wrong. I will try it without power first. If not I guess i can snag power from my unused hard drive sled or I can split the sata power from the ODD

    Advance Congratuations. Let us know how its performs and it's speed transfer. I think the fourth HD sled is your best bet to draw power.
