Solved: HP Z840 Power supply - HP Support Community -
2016-11-4u2002·u2002The 840 service manual states that the Z840 can accomodate two 300W cards each. Those cards would usually require a 6-pin and an 8-pin, per card. Looks like I'll be needing a molex to PCIe adapter too when I order a second Titan X. 0.
