Do I have to buy this cable, which seems both expensive and generally unavailable, to power a graphics card in my ML350 G6, or can I just hook it up to a couple of molex? I'm looking at something like a GTX 750 Ti or better. It's going to be used only for BOINC. My PSUs are 1200W.
Also, I would like to update the bios but find nothing available for my OS, Ubuntu 14.04.3, in the list for my server. I bought the server on craigslist and it's out of warranty.
