So i tried doing a psu calculation jus a bit ago, and i got a message saying i need 3.4kw from my psu which cannot be right.

My rig is going to be using

AMd phenom x3 720 3.0ghz
Msi 880-gm-e41 mobo
Gigabyte Geforce GTX 550 ti 4.2ghz
pny 4gb (2x2) 1600 ram
WD Caviar Blue 500gb
ASUS DRW-24B1ST 24X SATA DVD

and prob a 120-140mm fan or two as well.

 
Solution
PSU calculators are accurate, but we don't know and can't exactly what to put in.

A good old fashioned ROT is plenty good enough.

The psu requirement is almost entirely gated by the graphics card/s you will use.
In the case of a GTX550ti, you will need a 400w psu with 24 12v amps and a 6 pin pcie power connector:

No harm in getting a stronger one up to perhaps 650w.
Quality counts. My short list of quality psu's would include Antec, Seasonic, XFX, Corsai, and PC P&C.

Solution
For a single GeForce GTX 550 Ti graphics card system NVIDIA recommends a minimum of a 400 Watt or greater power supply with a minimum +12 Volt continuous current rating of 24 Amps or greater and with at least one 6-pin PCI Express supplementary power connector.

Stick with reputable name brands like Antec, Corsair, Seasonic and XFX.
