Is my power supply big enough? - silent pc power supply

In building a PC I do not know if my diet is sufficiently large (Odin 585W Silent Power Supply Performance)

Gigabyte P31-mother ES2C
7200 SATAII HDD 1 TB
4 GB DDR2-800
Intel Core 2 Quad Q9400 (2.66 GHz)
GeForce 9800GT 1GB DDR3

I can not buy a new diet and I just want to know whether it is strong enough.

Thanks
