When I read the previous reviews I was sure I found the solution to my problem which was the connection of a 3rd pci-e x16 VGA card to my motherboard which has only 2 x16 slots.
So I bought the product and tried to connect an ATI radeon HD5450 into a x1 slot through this adapter. Unfortunately, it didn't work as expected. The 3rd VGA never made it. The system didn't even recognize any device connected.
I addressed the problem to the company's support [...] and I spoke to the live chat with an advisor. The following is a quote from what he typed to me:
"The reason that the video card will not work with the PEX1TO162, is due to then bandwidth that the Video card requires to function. The PEX1TO162 is designed for use with device that do not require max bandwidth, like serial cards, and USB cards"
and later in the same conversation:
"Graphics cards that are not x16 based will work with the adapter. For example HD 4350"
"The card will work with X1, X2, X4, X8 and X16 based cards, however this is limited to the minimum bandwidth that that connecting card will require to function, so not all X2, X4, X8 or X16 cards will work with the PEX1TO162"
"It's more on if the bandwidth across the card can be compressed to a X1 level"
I haven't yet tried an older VGA in the range suggested (4350 etc). When I have I will come back to comment some more.
UPDATE: I tried an ATI RADEON X1600 256MB but it didn't work either. The slot is working properly because the fan of the card was working but still the VGA was not recognized by the system, as nothing was connected there. I finally returned the product.
