Sorry, one more question.

I've got a new mining rig I'm setting up.. I have a Thermaltake 1000 and Thermaltake 750 psu. I have a power "splitter" connected with the 1000 being the primary that powers the motherboard. Second psu seems to power up fine. For some reason, any card connected to the secondary PSU powers up (RGB lights come on), but no initial fan spin at all like the other cards. Never recognized in OS. If I just change the power to come from the primary PSU, fan spins and card comes up fine. I've tried with 2 different 750s as secondary and both do the same thing. Any thoughts on what I'm doing wrong??
