Re: building Pc question

4gb dual core corsair ddr3 1333mhz (xms3 dhx)

That should be dual channel by the way.

cooling fans ship with processors, so unless you plan to overclock, there's no reason to buy a third party heatsink or fans for a case that already ships with them (you didn't specify however...)

500 watts is fine for a 48xx family video card, as long as you don't skimp out and get a cheap power supply (i.e. a $30 unit that claims it can do 500 watts)
 
I probably wouldn't go less than 500w but there's no real problem going higher if you can ... just dont go mad and get a ThermalTake 1500w Toughpower or something because it's might be a bit wasted...

But like og said, dont cheap out, get a decent brand of PSU and a 500w should be fine.
 
I would agree with the others, 500w would be the best. It will actually be more energy efficient. A 500w will spin up its fan slower than a 400w as there is less demand on the unit.

Think of a small car pulling a caravan, its going to use more fuel and energy getting up to speed than a big off roader despite having a smaller engine.

I've never heard of those brand names, and if you're going to be a cheapskate on the power supply, you shouldn't be upgrading at all. You need to look at serious contenders for the power supply, it is what keeps everything else working and ensures that your system won't blow up.

As a minimum:
Cooler Master RS550-ACAAE3-UK GX-Series 550W Power Supply Unit: Amazon.co.uk: Computers & Accessories

and my recommendation:
Corsair TX Series, 650 Watt, ATX, PS/2, Power Supply, UK Version (CMPSU-650TXUK): Amazon.co.uk: Computers & Accessories
 
Branded power supplies are made by manufacturers who put their name on them for a reason. The fact that you don't see why there would be a difference is gravely disturbing in the computing world. Lower quality power supplies made by no-name companies, or cheap knockoffs are made with lower quality components, and due to the nature of how a power supply works, if those components aren't of a certain quality, you introduce things like noise, ripple and component failure which can not only cause a power supply failure, but in the case of cheaper power supplies, actually take out other components in a system. A friend of mine cheaped out on the power supply for a high end computer, and the PSU fried on him one day, it took out his motherboard, his CPU AND his video card and hard drive. His "savings" turned into a liability because he didn't spend the extra $30-50 on a high end power supply. It's a type of insurance that really does matter.

A good gauge of power supply credibility is its weight. Cheap units will weigh less, because they don't use as many heatsinks and quality components, which tend to weigh more. It's not the only indicator, brand names fall into play as well, but generally between reviews online, the weight of a unit and the name brand can be used to gauge a good unit. Here's a couple of links that go into the whole deal on these devices:
