I believe you'll be fine...for how long, not so sure.
indeed, i hear some pretty nasty things happening during PSU degrade... and i forgot to register the Ultra lifetime warrenty within the month... so i only get 3 years XD

You're pulling 400w from the mains on a 78% efficiency PSU... that's only 312w besides the 5830 is supposed to suck between 25~200w so you should be good, but as already mentioned Ultra's are of dubious quality

correction, 400W at 78% effeciency = approx 320W output, so that means that a second one bumps up input to about 600W, and output is about 500W, (closer to 470W) so i think my PSU should at LEAST be able to push that much.. but what about PSU denigration, how much will that factor in? and how long till it cant handle crossfire? 3 more years?

alrighty thanks guys... so what do u guys think? is it worth crossfiring another 5830? it would beat GTX 295 performance by a nice margin, and everyone remembers that massive mofo am i right , so for 120 bucks is it worth it?

It's not worth it with your current psu as it will most likely die and could kill the rest of your components. Wait till you get a decent psu!!!

Yeah the LSP series was one of Ultra's Ultra failures. They still use cheap oem's to this day so Ultra psu is totally out of the question for decency.
