500 W is probably fine. But ~550-650W would protect you against having to upgrade if you did a GPU upgrade down the track.

Thanks for this, too, I think I'm going to go with you here purely because it's justifying my being frugal with PSUs even if it's possible that I will need more wattage in the future. Do you have any tips on specifics i.e. model?

For all the praise I've heard about the 6850, I'm not hugely convinced that's true, but it sure as hell would save £30 - £40. Thoughts? I know it's worse, the clues in the name, but I'm starting to run out of places to cut costs down!

Would the above rig be hackintosh compatible? And, if no-one knows, does anyone know of a fairly comprehensive list/site on which I could find out?
MrJP wrote:If you still haven't ordered, then you can stretch the budget a bit further by going for a case/PSU package rather than separate items. For example, this Antec VSK 2450P is around £70 at Ebuyer. The entry level PSUs that Antec uses in these cases are fine, and certainly not disimilar in quality to the Corsair builder series that you initially selected.
You can then use the extra money to stretch to a 6870 rather than 6850 to give you a fair bit more headroom on the gaming performance. e.g. Powercolor 6870 for £135, with Sapphire and XFX variants at £140 if you don't like Powercolor (some people have a semi-irrational distrust of their products, but I've never had any problems and these cards are all reference designs anyway). The 6870 is right in the sweet spot for GPU value at the moment, a good step up from the 6850, and you won't get significantly better performance without spending a lot more money.
Note that I've only looked on Ebuyer because I tend to find they're consistently the cheapest relaible supplier in the UK, helped by offering free shipping if you're prepared to wait a day or two longer. You might want to look at pricing up the whole system there to see how it compares to Amazon. Scan are also very good, but shipping costs can be on the high side.
Edit - before someone else rushes to pont it out, I've realised that I've made a schoolboy error by recommending a graphics card that needs two PCIe 6-pin power connectors in conjunction with a PSU that only offers one. You could use a Molex adaptor to power the other port (one might be supplied with the graphics card) and this would work OK - the PSU has enough capacity for this system. However according to the Antec site the PSU only has 4 molex connectors to start with, so this might leave you short if you need them for additional fans etc. I still think you should try to get a 6870 if possible, but the case/PSU might need a rethink to get a tidier solution.
