The right PSU for SLI

[anqwerty]

Hey guys,

I have rather unusual build so I don't know what PSU I should buy.
Specs:
Asus Sabertooth z77,
Intel i7 3770k,
2 GTX 550ti in SLI,
Corsair Vengeance 2 x 4GB,
Fans: 4 x 120mm case fans, 1 x 120mm CPU cooler fan, 2 x 90mm case, 2 x 40mm on motherboard,
Kingston SSDNow 60GB,
WD Black 1TB,
DVD RW optical unit.

I was wondering if 650W 80+ Bronze would be enough, but i doubt it. So my question is if 750W 80+ is enough or do I need to buy stronger PSU. Also, I was planning on some moderate overclocking in near future.

Thank you for all the answers.

without overclocking the 650W psu should be enough. the 550 aren't so power hungry. 750 gives you headroom for overclocking.

A 650w would be enough for that rig.

A good quality 650watt PSU will be fine.
What country are you in and what's your budget?
I'll recommend one for you

I'm from Slovenia. Budget is from 80 - 100€. I would prefer a better PSU though for a bit of overclocking.

That one, besides OCZ ZT Series 750W and CM GM Series 750W, is the one I was looking at aswell.
Thanks for the answers, really helped me out
