I'm considering upgrading to one of these cards, so I'm wondering if my power supply could handle the power draw from either of them. This is from the manufacturers website, my psu is the 550w one.

Yup, you shouldn't have a problem.
5870 requires at least 40 amps, and your PSU can pump out up to 50A.

Leaves you with some overclocking headroom. ;]
You don't have the best PSU, but the wattage is enough for a 5870.

However, you can't run a 6890 with that PSU for lack of adapters. (8pin PCI-E + 6pin PCI-E)

I dont think you understand.

Do you know that there is no "standard" for PSU's?

So if a manufacture made a 250W PSU they can sell it as a 500W if they wanted to.

If it's 80+ and can push that many AMPS, I'm pretty sure it can handle a 5870.

I have never had a problem with Chieftec PSU's, I've had CFT-650 and now this APS-100C and I have built 3 systems in addition with Chieftecs, each a CFT-750-14C.

Where did you get 50A from? His PSU has two 12V rails, rated at 25A each. The combined wattage is 450W, making it 37.5A.
