Need an idea what to go for PSU wise. 650 or 750Watt I am guessing but the brains on here I hope can put me straight?

PC spec.

CM Storm Scout case - 3x 120mm fans
Phenom II 965 black CPU at 3.8-4.0ghz
Cooler master CPU cooler with twin 100mm (?) fans
Gigabyte GeForce GTX460 graphics OC (not clocked-yet)
1x SATA
1x DVD/R
1x FDD

No plans to SLI. Looking for a PSU which will run that lot at around 80% of max. PSU load. Modular pref and Antec or Corsair.....probably :p

Cheers,
Paul
 
You'll get away with 450W. 500W for a little leeway for peace of mind (and if you start adding drives). Unless you're going to change your mind later and swap to SLI, there's no chance you'll need more.

Very few people ever add SLI at a later date after deciding not to. Either you build it in to start with and plan accordingly, or you plan to have it but can't afford it initially so add the second card 6 months down the line (often scrapping the idea when one card is fine).

If you decide you can't afford/don't need SLI now, then by the time you'd change your mind then it usually makes sense to just sell it and upgrade.

Say you change your mind in 2 years. Your current card may be worth £50. You can either spend £50 getting another, or sell that one for £50 and spend £100 on a new model. You still spend the same money (since you sold it for £50), but you get a single card, probably a comparable increase in speed, and you don't have the complexities of SLI or a 2 year old card to worry about.

That antec is particularly good value, so you may aswell get it instead of a 500W, but don't bother spending any more than that.
