Radeon R7-Series Power Consumption

[MrBoomBoom]

Hi!
I'm looking to get one of the new Radeon R7 graphics cards. The 240 and 250 cards seem great for the price. I currently have a GT 630, so pretty much anything will be a considerable upgrade
Anyway, I noticed that there are n "recommended" PSUs. I currently have a 300W PSU. On the AMD website, all it says is that it doesn't need a 6-pin connector, just like the 7750. I'm assuming that the new r7's will work on a 300w PSU (the 7750 does), but I'm not sure.
Does anybody have an idea of the card's power usage?
Any help is appreciated

Here is total system power measure at the wall with R7 250 http://www.hardwareheaven.com/reviews/1856/pg9/his-radeon-r7-250-icooler-1gb-graphics-card-review-power-temps-oc-and-media-playback.html Looks like it will run fine on 300watt
