Can you trust these online PSU calculators? I have tried 3 different sites and have received 3 diffrerent results! I would really appreciate some advice and recommendations for a PSU to deal with the following;

AMD Phenom II X4 965BE
Gigabyte 990FXA-UD3
Asus 7770 1GB DDR5
128GB Vertex 4 SSD
1TB Seagate Barracuda 7200rpm HDD
2x4GB G.Skill Ripjaws DDR3
Asus DRW-25B5ST DVD/RW

Thats most of if I think - anyone have any good suggestions / reccomended wattage, etc?

Also, when it comes to brands, how do makes like Aerocool stand? I've seen a few 80 Plus Bronze models at good prices, almost too good when compared to XFX, Antec, etc? Are they good?

Thanks!

Any quality 450w PSU would run that setup fine.
As for whats a good PSU, check out reviews at sites like JonnyGuru, hardocp, hardwaresecrets... Most brands have good and bad PSU's.

500W.

A decent one, not some Logisys or Diablotek one.

Best brands are Corsair(CX500), other brands would be more expensive for no benefit(for this build), like Seasonic.

Hi - aerocool - not cool, most of their units are made by HEC & Andyson,
both have a less than stellar reputations.

pop is right - find a decent brand & model (450w or a little more),
and check in here if you don't find a quality review.

Quality brands: Seasonic, XFX, Antec, most Corsair's, most Enermax,
Rosewill Capstone series, Silverstone, PC Power & Cooling, and some others.

Calculators are probably dead accurate, assuming you can give them accurate input.
Unfortunately, some inputs are unknowable.
Capacitor ageing factor for instance?
Or, how much reserve do you want?

It turns out that for a normal pc, it is the graphics card that is the determining factor.
Here is a handy table of graphics card/s and their recommended psu requirements.
It assumes a normal complement of cpu and peripherals.

It is not wrong to overprovision a psu by 10-20%
It will tend to operate more efficiently and quieter in the middle third of it's range.

Whatever, buy only a quality psu. Cheap psu's may not deliver advertised power among other deficiencies.
Here is another handy chart for psu quality:
