Is this power supply enough for a HD 4870?

I have a Thermaltake TR2 550W PSU.

It has two 12v rails with combined 29A on them.

The question is if it's enough for a HD 4870?

Id say it should be fine, Im running my 4870 on a Thermaltake PSU thats only 430W.

That's really pushing it - that PSU only has 25A combined on 12V. For a 4870, I'd be really cautious if it's under 30A.
