Which of these PSU's is better?

[falcodakrzz]

Basically ive got two PSU's, one of them, the enermax, isnt in use. It will be used to power a crossfire 4850 system.
Here they are:

So which would be best for my system?

Thanks

I've never heard of X-Power, and a Google search didn't turn up any reviews (even after Xantrex was excluded). The Enermax is on tier-3 of an old quality listing at http://www.tomswiki.com/page/Tiered+PSU+Listings?t=anon. If you can't find anything better, it is probably safe.
