Power question with upgrade to Gigabyte 4850

So, I'm upgrading my video card and my current one (nvidia 8600gs) doesn't require power connectors from the PSU. The one I'm wanting to upgrade to (gigabyte 4850) requires a 6-pin connector, but also comes with an adapter that goes from 6 pin to 2x4 pin molex connectors. My PSU is 550 watts, but older, and doesn't have a 6-pin connector, so I'm wondering if the 2x4pin molex connectors will be enough power for it.

if you have 24a+ on the 12v then you should be good to go

This is what the side says:
DC Output: +3.3V +5V +12V -12v -5V +5VSB
MX Output: 26A 45A 28A 1.0A 0.8A 2.5A
Wattage: 220W 336W 12W 4W 12.5W

so, I assume the 28A is good enough?

Do you know that the HD 5770 is faster than the 4850 and uses less power?

5770 is superior to the 4850, but the 4850 is a cheaper fit for a budget build or to extend the life of an older computer. I upgraded from an 8600gt (old Dell) to a 4850 (new build) and the difference was night and day. I chose the 4850 due to my budget constraint.
