Hello, I´m new here, so I don't know if it is correct to post this or not (if not please mod, delete it and I am sorry).
I just received the powered risers from cablesaurus that I bought online
it only took 10 days to arrive (I am in south-america, so it usually takes longer)
PIC:
I notice that the 12V molex is in parallel with the PCI-E 12V line, so it should be a good idea to use a single rail PSU for these.
one of the 16x risers had too much tape over the contacts so i had to remove them with a cutter (and care
), other than that, they are pretty good.
I tested all of them with and without the 12V molex connector, in my motherboard the 1x to 16x won't work without the power, but the 16x works fine.
I am currently using all four on one motherboard with 4x 7850 and they are working good.
just want to share this experience, I'm sure it's old news for most of you anyway but... there is always someone clueless, like me
, that this info could be useful.
