sunbeam question

I've been looking into panels lately in order to tool up for the case I plan to get. I'm liking the sunbeam rheo but I'm hesitant due to a review I read somewhere...

The reviewer said the thing is awesome but is a real current-monger, and recommended using with 550 watt psu!!?? I don't wanna believe the hype but--

I run a truepower 430 and will have 4 or 5 casefans in my future setup. Will probably have 2 op drives and one hd. Is my psu adequate for this panel? If not I'll go with 3.5" nexus, but gotta love that sunbeam.

doubtful that you'd need anywhere near a 550w psu.

The only thing to suck more current than your fans themselves would really be the LED's. It seems as if a Rheobus' construction is passive.
