Looking for reliable PCI-E USB 3.0 controller

Surprisingly, the majority of up-to-date MoBos recommended for hackintoshing have only got a single internal 20-pin USB 3.0 connector. I need at least two of those - one for 2xUSB 3.0 ports built into the front side of the case, and another for combo card reader.
So which of the available cheap (under $20) PCI-E USB 3.0 controllers work best with OSX? I would even prefer the card without outward-looking USB ports, internal 20-pin connector would be enough.

I've looked around ebay/aliexpress, and the majority of sellers do not provide any info on the chipset used.
Has anybody got any recommendations on the described item?

Some of the Orico models are known to work. I don't know the exact model numbers off the top of my head, but if you read through a few threads you should quickly find a small list of suitable models to check out for full specification and price/availability:

This is working for me:

Inateck 2-port PCI-E USB 3

No drivers and no need for auxiliary power. I bought it to use the internal 20 pin port to power my front case USB sockets as the socket on my Mobo broke.

Deleted as I was wrong.
