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.

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.
