spdfreak, someone replied to your (presumably) query at hardforum saying they have success with an Antec 350W rated 16A max. :Q 
Maaybee it will shorten the lifespan drawing near max but then again that's only during intensive 3D and in any case it beats the hassle of replacing until actually necessary. The only caveat is that shoddy units tend to commit murder suicide rather than simply trip an internal breaker when they've had enough (no mas!). I have faith in my good ol' FSP to do the latter.
