650 Watt Power supply? (GTX 260)

I have an Ultra LSP750 and it is pretty sturdy in quality so far. That one you are looking at has 38A on the 12V rail, so you should be fine. However I would look into something like Corsair, PC Power & Cooling for something similar in price.

If its the 216 core, u should be looking at 700, just 2 be safe, when it is using all of its power, i got the 260 (216) in sli, and it hogs most of my power, i thought 800 would be fine, but the gpu was giving me warnings bout insufficient power, so i upgraded to the 900, it was fine when idling with the 800psu, but when it came 2 some crysis or some benchmarks, it started choking.

If its a gud 650 one, then u should be fine, unlike the no-name brands, (i got a antec trupower, and works at a constant 900 with very very little fluctuation)

Its all about the brand, you dont need a huge PSU, my computer under load uses 350w peak power, get a good branded 600w to be safe, 800w if you are usng Quad Core and maybe SLI/Xfire/Sound Cards etc.

As you can see on my sig, I have that card, a Quad and a 650W PSU.
