Need a new PSU.

[Harrybololxd]

I'm kind of in need of some quick help/information about psu's. I have gone through some calculators but still my mind isn't at ease.

Current Setup -
i5 @ 4.6ghz - custom water loop
8gb 1600mhz ram
250gts 512mb
Asus P8P67
Corsair 520hx
7200rpm hdd (only one)

I have a massive dilemma if I should go for a 750w psu or an 650w psu. I will be buying a £200-300 6xx nvidia card when it comes out and *probably* no sign of wanting to do SLI but could change depending on income. I understand no one knows the power rating of the cards yet but..

I can get a Corsair TX750 for £83

or

Antec True Power 650w for £60

Both units new, Which should I purchase? It's been playing on my mind for a week now and just decided to make a post.

Thanks, any help appreciated.

go for the Corsair, because of the brand D: also the extra 100w may come in handy in the future.

Make sure that Corsair is a "v2" version.

why not wait and see what the power requirement are for the new cards?
not sure on the nvidia cards but the amd/ati are ment to be more power effecient then their current gen equivalents, you may not need to chang the psu unless you plan on getting the top end model.
