Newegg looks similar to Conrad
http://conrad.de/ce/de/product/973583/2-PORT-USB-30-PCI-EXPRESS-CONTROLLER
To compare more I moved mouse over picture in each,
when a magnified version spring up & pans with mouse, but a problem
then: one can only hover the mouse over ne pictures at the time,
not both. (unless anyone knows some trick with X or firefox to
freeze one ? )
One couldnt even use 2 different browsers & ^Z as one still have
to pan mouse to controlling Xterm before hitting Control Z.
So one would have to look at source of bpth pages & try to download
both larger pictures (if that's possible & it's not some live java thing,
I dont know, haven't looked).
It's not identical.
The white paint of the silk screen on PCB ends with:
Conrad.de : 8-00B MADE IN TAIWAN (no preceeding 1122 )
Newegg.com : 08-00D MADE IN TAIWAN (+ preceeding 1122 )
Electricaly I don't know.
My posting

Lists all numbers off top of chips, (it was very hard to read one
chip, even with magnifying glass & good light, I wouldnt want to
try to read pcture on newegg web page, but people have my IC numbers
for Conrad).
Newegg.com page has:
"With a built-in SATA power connector, each USB port can deliver
up to 900mA of power"
That's too low, should be 1.0 Amp I believe for USB3 spec.
http://www.conrad.com/ce/en/product/973583/ (english page BTW) clicks to
http://www.produktinfo.conrad.com/datenblaetter/950000-974999/973583-an-01-ml-2_PORT_USB_3_0_PCI_EXPRESS_C_de_en_fr_nl.pdf
Page 2 says:
"each USB port of the plug-in card can deliver a current of up to
1.5A (SATA power unit must be connected to the plug-in card!),"
Cheers,
