Well, first of all that one appears to be out of stock, and second I wouldn't trust the cheapo 350W PSU that comes with it any further than 23% of the distance I could fling it by the wires. With that GPU, (which may not need its own power connector; my eVGA 7600GT doesn't), you'll still probably want 2x+12v rails with 16A-18A on them. Total wattage may look like enough (my system draws <180W), but wattage where you need it probably isn't.
Is this plenty for it?
And enough for upgradeability??
Will it work? Probably, but you can get a fortron PSU (or one made by them under another name) for around the same price.
It might be worth looking on silentpcreview. They're geared towards quiet computing, but they have some of more thorough PSU reviews out there.
Watts on PSUs are like Watts on a receiver....if you buy a cheap receiver that says it's 100 wats/channel, it's not the same as 100/channel on an expensive receiver.....they're probably not measured in the same way.
