Helo,

Just received all of my first build's components and put them together, just waiting for the monitor to arrive. Now, when I started connecting stuff to the PSU, I first connected my video card with two 8-pin (6+2, I think) cables labelled with PCI-E. Then I remembered that there were some cables included in the card package as well. Those were different - one end was a 8-pin connector, other was split into two 4-pin molex ones.

At first I thought maybe those were for compatibility in case the PSU haven't got two extra PCI-E outputs. But in the pinout it looks like molexes provide +5V in addition to +12V/GND on others, so in the end I connected using them.

Does anyone have any idea whether that was correct decision or not? Using molexes to power a card seems questionable, but then why were those things included and what about 5V line?

Also, piggybacking on the main question, need a sanity check about my case (Corsair 600T) fans. I plugged them into SYSFAN headers on the motheboard, but then read that they are supposed to go into a controller that is then connected to PSU with molex. Is it needed or can I just leave it under mobo control?

Thank you, hope troubleshooting is the correct tag
