At least 700. The 690 is two 250W 680s on a single board

At least a high quality 550W unit, though 650W would be preferred.

That being said, with SLI being pretty much dead nowadays, in most games the 2nd GPU will probably just idle so you probably won't reach the max 300W mark the 690 is rated at too often. I also can't recall how much power Athlon IIs used to draw but I'm going to assume under 100W, so you'll land at around 450-500W power draw max I reckon.

 

If you're actually planning on purchasing those parts now though, I'd advise you look towards a used Dell Optiplex instead with something like a 3rd gen i5 or i7 and throw in a cheap graphics card and call it a day. As I mentioned previously, you won't be able to take advantage of the 690's full power in modern games and the Athlon is legit ancient.

Reference 680s were rated for around 200W I believe, and the 690 had fairly cut down 680 cores on it, unlike what AMD was doing at the time where they had fully unlocked 7970s on the 7990. It really doesn't pull that much power for a dual-GPU card.

I had one that easily pulled over 450W on its own back in the day. Guess mine was shit efficiency-wise but yeah, 550W is not enough for a dual-GPU card imho.
