Modular PSU or non modular?

[Steve09]

Popping to OcUK tomorrow to buy my new stuff and I was wondering, should I get a 650 watt Corsair PSU non modular for £65 or a modular Corsair 520 watt for £70?

I'd obviously like the 650 watt, but is it worth spending more for less watts because its a modular one? I want the case as tidy as I can get it.

Thanks

Well I've been and bought now
I got the 520 modular version, but now I'm thinking if I should have got the 620 watt modular version.

I plan on running an ATI 4870 and I may go watercooling sometime in the future with 1 pump...

What you think?
