Here is my situation, I would like to update my graphics card, been looking at the radeon hd 5xxx series and liking what i see. I would like to get an HD 5850. However I don't know if it will push my psu too close to the max. Using the extreme psu calculator it says I should have 494 W and 33 amps on the 12 v.

Do you think I am safe with this configuration?
If not, my other options were
Get a hd 5770, which would draw 445 w and 29 amp with the same configuration. Based on the prices I have seen (I am in Canada btw) the5770 is about 50 dollars less than the 5830, and since I only run at 1680 x 1050 it seems like a more reasonable option. I typically upgrade video every two years.
Or I could go 5830 and use the approx $70 difference between the 5850 to invest into a new psu right now.
My preference would be the 5850 as I said earlier, I don't have a lot of money to play around with for this,
If you have any comments suggestions or whatever I would be greatful, thanks!
I'd think you'd be okay as well. At your resolution, an ATI 5770 could get you by pretty decently. But I'm always one for buying more than you need so you don't have to upgrade again in 6 months. LOL
The ATI 5850 is a great video card for you to be considering. So kudos on doing your research. As Number13 suggested, I wouldn't opt for the 5830. The price not being a huge difference, and it actually using more power potentially. Besides that, I'm not so sure the 5830 is a great balancing point between the 5770 and 5850 anyhow.
If you can buy online, NewEgg had 5850's just under $300 recently.
