Will this PSU work well for a crossfire setup?

[elbarto]

I've got a Antec TruePower 2.0 TPII-550EPS 12V PSU. It says it's SLI ready but that doesn't mean much.
I want to run a x1900xtx and a x1900 crossfire and I want to know if this PSU is enough.
Specs for the PSU can be found here.
Any help is much appreciated.

Thanks

I think it is also Crossfire certified...
