Calculating total Power used from PSU.

[serth]

Hi guys

So I've been installing new hardware over the past couple of months into a new rig, but im begining to think that my PSU is not powerful enough. Is there a way to calculate the total power being used by my components?

Spec:
PSU: OCZ Stealth X Stream 600w
CPU: Intel Core 2 Quad Q6600@ 2.4ghz
RAM: 2x2gb Kingston Hyper X 1066mhz PC2 8500.
GPU: nVidea Geforce GTS 250
HDD: 2x 500gb Seagate Barracuda 7200rpm
MOBO: Asus P5QLD PRO
O/S: W7 Ultimate x 64

Also taking power: heatsink fan, side fan, front fan, themometer and optical drive.

I am thinking of adding a further 2gb of the same RAM and another 1tb seagate baracuda 7200 hdd. Also adding a rear Fan. Will my power suply be able to handle this?

Is there a way of calculating the total power being used that anyone could reccommend?

Many thanks

Build your rig into this http://www.thermaltake.outervision.com/ to get a rough idea of power needed before and after the planned additions
