I think that 1250-X has 3 PCI-E dedicated power outputs and one mixed CPU/PCI-E. So if you use that mixed port for PCI-E you have 4 connectors per power supply to feed the cards. The entire system usage is around 1700-1750 under full load so 2x 1250 should be enough if you distribute the load.
Be sure to pick a motherboard which you can feed additional 12V for the cards else you will draw too much power on your 24 pin connector and it will melt ;-)
That is why I personally choose the ASRock which has 2 extra 12V inputs for the PCI-E's.
