We aren't both wrong, the article says it draws 133 watts. Which as I said is less than 150. A 650 could run it but, a 700+ is what they suggest for headroom, which I did as well.
Just because a card uses two connectors, doesn't mean they put them under max load. Some cards will use two 6 pin connectors to even the load on PSUs with more than one rail, to keep the power draw clean.
Blfer, you should really upgrade your PSU, you are cutting it too close and probably starving your system. The 290s can spike up to 365+ watts, although you might not see instability, you might have reduced performance.

No, as I said my model with 6 and 8 pin connector needs 300 watts max (75 + 150 + 75). That's tested. There are other 290s with two 8 pin connectors, which need max 375 watts (150 + 150 + 75).
This + my CPU, a Xeon e3-1231v3 + some other stuff like SSD, fans etc... is much lower than 480 watts. Even a 450 watts power supply would be enough.
Edit: The spikes to >360 watts in your linked test are too short to be relevant. Even an underpowered PSU can handle them.
