Does this card need additional power? Does it effect the mac sleep mac os 10.9.x?

it will operate without power, as long as the device has a power adapter of its own. so mostly, it does require power. my machine still sleeps, but it will disconnect the device abruptly, meaning possible data loss.

I would assume the need for power; all third-party USB-3 cards that I've seen seem to. As for sleep, I would ** think ** that if they're compliant with the PCI-e spec, it shouldn't be an issue....??

Yes, it needs a free power socket. I use it on Mountain Lion so can't answer regarding Mavericks.

It's should work fine the card does not need extra power. All it need is the power from you PCI Express and you good to go.

It only works in El Capitan if you disconnect your USB3 devices before putting it to sleep, otherwise the MacPro will *NOT* go to the sleep properly. If you disconnect everything last thing at night or whatever, the MacPro will sleep too. At time of writing, this hasn't changed past 10.11.3. Officially Inateck only supports the KT4004 card to 10.9 Mavericks, but it works a treat on Yosemite or El Capitan if you disconnect before Sleep as I said.

I don't know. I am not using the power port. My laptop has enough power to the card that everything works fine without an external power supply.

Hi there,The power is supplied through the USB 3 cable by the PC or the Mac.And it works perfectly well.As simple as that.Cheers.Bernard

Yes - but I do get disconnects from time to time. Not sure if this is the disk, the card or OS X

If your using an external USB device that has its own power supply (i.e. external HD that plugs into the wall) I'm pretty sure you don't need to power this card.

Depends on the rest of your hardware. This card uses 150w, you will have to calculate the rest on your own. Minimum recommended is 500w.

(Just to check the obvious), but have you tried moving the card to a different bay? Does the system have a lot of accessories or a high-power graphics card (enough that adding this card might overload the power supply -- if it's one of Apple's cards, you're a long way from this).I have used this card in a 2010 MacPro without trouble. Good Luck.

This card will work... Barely. It's a passive heatsink card, so no fan to draw extra power. As long as your system is otherwise stock, and there aren't any other power draining components, it will work.

Officially, no. It takes some time plugging and unplugging into the Mac, but it will work eventually. Also, the computer will forget it's there when it falls asleep.

No, MAC Operating system and hardware only allow certain video cards, this is not one of them

Can't answer that since it would most definitely depend on what other components you have. This card does not require a lot of power by design, but the total power load would depend on the other components in your system - not just this card.

Turns off with the computer. That said, if it is connected to a Mac it will will still work when it is in sleep state as Macs do charge external devices while in that state.

the wattage should be fine but you also need supplemental power plugged directly into this card from the psu.

I have the same MacPro. I purchased the 4 port card and did not need to run the internal power when the hard drives (or other usb devices) were externally powered. I even ran a bus powered drive off of it. Then I read that for bus powered drives it was *recommended* to have the internal power, but I haven't found a good source for that cable (please let me know if you find one). In the end, if you are externally powering, then either will work.

I am using 400W power supply with this card and it works just fine. This card has pretty low power requirement especially since it has no cooling fans. This card is designed to be fully fanless by using bigger heat sinks. I mainly used it for the good performance, smaller profile and fanless design. Please let me know if you have further questions.
