The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

I have a 5x 290 rig, and that pulls ~1750W at the wall with 2 80Plus GOLD PSUs. Your 1250 is not cutting it. You need to buy a small secondary PSU, and move at least one of them off to it.
And no, last I checked VBE7, doesn't work on 290 cards. It only works on the 280x, and any Tahiti cards. The 290 and 290x are Hawaii chips.

Got around 730k per card. I think the new R290's do pull more power, so I would have to agree you will need another smaller PSU.

I had stock 290s pulling 260-270 watts on 95-99% load.
Seasonic 1250 can go hold at least 1500 watts.
Adding a secondary PSU wouldnt hurt to spread out one of the cards, no additional motherboard and cpu draw if using a dummY plug for the 24pin atx.

Dude, I seriously recommend that you stop doing that right now and wait till you get another PSU.
