Power supply for 390x 390x X2

[rossiboy001]

I know these cards are not out yet, but i guess they will be very similar to crossfire 290x and 290X2 requirements, but its easy to say just get a 1300 watt or so, but its the rails that Im unclear about, and dont want to end up spending a lot of money on one not suitable and blow things up. I have refrained from getting a 290xx2 or going crossfire this time round, i have kept the money aside, but in the meantime selling one of my 680"s and a few quid more on top, gives me about £200 spare to put back into a new PSU. This to replace my 750 watt, and i can pass that on to my son with the lightning i have. Therefore Im ready for when the new cards are available without having to do the tedious task of installing a new PSU at the time, and it gives me something to be getting on with too. So im looking for something that will be suitable for crossfire 390x or 2x390x dual card? Which cards should i be looking at?

Yes sastusbulbas. i was considering the superflower gold for about £150 its price yoyo"s as adequate, I think we are all clear about the power wattage, its just the rails cause that can make a difference, you can overload a PSU i guess by having the wrong configuration, i recall from watching videos for example the 2x290x has specific requirements.
