Wanting to setup 4 Vegas on 2 EVGA 750W PSUs on a Asrock H110 BTC Pro+. However, what I didn't realize was this mobo requires not one, not two, but THREE additional power connects (2 molex and 1 sata). I was planning on using 2 vegas on each 750, but I'm already out of perifs and I haven't even plugged in ONE Vega?
Wth?
The 750 G3 has four 8-pin VGA outputs (2 needed per VEGA), 3 6-pin sata (one for the HD, one for the SATA power to the mobo, and one for the 2nd Molex power to the mobo) and one Perif (one to the 1st molex power to the mobo).
I can't even plug in ONE riser. I've got to be missing something. How are you all managing this? I honestly need a PSU just for this dang mobo alone!
For only 4 cards you don't need connect those 2 molex and sata conectors of the motherboard.
Just disable the warning on the bios.
Also, don't put more than 2 risers per cable, if you can put 1 riser per cable is better.
The EVGA 750 G3 came with 2 normal cables PCIE and 2 double PCIE cables.
All you need is use the normal cables for the risers (if you have the risers 006c version), you have 2 psu so there is enough for 4 risers.
All other 4 cables are double PCIE, thats enought for the cards.
My guess is that you don't have PCIE (6 pin) risers right?
Those are the best ones.
