I intend to buy the following parts and wanted a recommendation for a PSU:

Intel Core 2 Quad Q6700, Kentsfield Core, S775, 2.66 GHz 1066MHz 8MB Cache, 10x Multiplier, OEM
Akasa 965
Gigabyte GA-EP43-S3L iP43 Socket 775 8 channel audio ATX Motherboard
4GB (2x2GB) Corsair TwinX DDR2 XMS2, PC2-8500 (1066), 240Pin, Non-ECC Unbuffered, CAS 5-5-5-15, EPP
HD 4830 512MB GDDR3 DVI VGA HDMI PCI-E Graphics Card
1TB Samsung HD502HI EcoGreen F2, SATA 3Gb/s HDD, 5400rpm, 16MB Cache, 8.9 ms, NCQ
Antec 300 Three Hundred Black Case - No PSU

I am thinking of the Corsair 450W VX Series PSU... any views or recommendations?

The PSU choice sounds good to me! :D  You could consider a WD 1GB Caviar though...

The samsung drive is faster than the WD and quieter .

450 watts will power your system , but I would go higher . 550 ish

Any recommendations for a higher power high efficiency PSU?

Also, the disk spec is wrong in my original post - it is a 1TB Samsung HD103UJ Spinpoint F1, SATA 3Gb/s, 7200 rpm, 32MB Cache, 8.9 ms, NCQ

Look for a PSU that is 80+ certified, like an Antec Earthwatts. A lot of Corsair and PC Power & Cooling PSUs are 80+; all of them maybe?
If you don't plan on any upgrades beyond the 4830, you could use an Earthwatts 430, which is $55 right now (actually, this PSU can handle a 4850).

I'd definitely get at least a 600W PSU to be safe. I'm not saying the 450W would not work but why push it?

I have just read a review on anandtech and they think the BFG LS-550 550W ATX Power Supply Unit PSU is very good... does anyone have any experience of BFG PSUs?

I don't think i'll upgrade the PSU for some years so is it better to go for a higher power unit?

Well, manufacturers always push to provide more performance with the same—or even less—power consumption. So I think if you get a good PSU, upgrading it won't be a concern. Unless you change the equation significantly by adding another video card, place 4 more hard disks into your system, etc. In any case, PSUs are relatively cheap, so upgrading to a more powerful PSU will be cheaper in the long run than paying a higher electric bill for a PSU that unnecessarily consumes more power.

Regarding the BFGs, just saw someone in another thread recommending the LS over the GS series. I wouldn't know why though.
