"super power" is generic crap. probably cant even do 400w. ultra is a step up from what you have. it would probably work. but i recommend a 450w or greater of a reputable brad like seasonic, antec, corsair, or some enermaxes, silverstones, and fsp units. corsair is the best imo

According to Tiger Direct that 500W ultra PSU has a single 12V rail with 28A(336W), thats just bad for a 500W unit. Get a good until like a Seasonic S12II, its a bit more expensive at $60 from newegg, but provides 40A on its 12V rail(480W) and has plenty of power for any single GPU so you dont need to be concerned, im a bit skeptical that an Ultra LS500 would survive running a GTX 275 for very long.

obsidian beat me to the link, but the ship time from amazon is 2-5 weeks so it might be worth a bit more to get it from newegg in 3-5 days.

Using not enough power can cause it to go boom, if it goes boom it can take out none, some, or all of your computer with it. I say its not really worth the gamble.
