The build goes something like this...

AMD FX-4350
COOLER MASTER HYPER 212 EVO (cpu fan)

ASUS M5A97 LE R2.0
CRUCIAL BALLISTIX 8GB (2x4GB) DDR3
GIGABYTE AMD/ATI RADEON HD7790 2GB GDDR5 PCIE GV-R779OC-2GD
KINGSTON SSD 60GB SATAIII
SEAGATE BARRACUDA 7200 3TB
and some extra few fans for the case...

maybe another HDD in the future...

Here's the question.
How many watts PSU will be optimal for this. I'm thinking about 600W, but I realy dont know much on the matter, or how to calculate it right.
please advise!

That system will run with a good 500w psu, but a 600w gives you a little more headroom. Be sure to get a quality psu with a minimum 40a 12v rail for a 500 or 45a for a 600.
