    Order and delivery were fine. Information about this specific item "ATX 3.1 PCIe 5.1 12V-2X6 12VHPWR to 3 x 8 Pin PCIE Adapter Cable" could be more specific regarding the use. It seems to work independent from power supply as long as it is connected to the end of the power supply specific 12VHPWR cable.

    The site is decently organized and has lots of obscure small parts. I'm reminded of radio shack and how helpful it was to find exactly what I needed for my project.
