New build confused about powersupply

[KILMDADDY]

Im a bit confused about power supply's i used this website http://www.extreme.outervision.com/PSUEngine as recommended in one of the threads here and it gave me a result of 299 WATTs is this right? It sounds a bit low but im not to sure as its my first build. If not would my Antec EarthWatts 380W be considered adequate?

Here are the proposed specifications.

Thanks for your help.

With a 8800GTS I don't think the Antec 380 watt PSU would be enough. If I were building this computer the minimum I would install would be a 450 watt unit but would probably install a 550 watt unit to give the system a little more headroom.
