The Antecs are your only choices in that list.

My suggestion would be a 650 Antec Earthwatts. You'l need your old power cord btw.

While 550W is fine, I'd go to 650 so you have wiggle room for old age and bigger gpus.

If you can find a Corsair tx or txm in 650 for a reasonable price, its another great option.
