I'm about to buy a new system with the following components:
i5 3570k @ 3,4 gHz (I'm not gonna OC anytime soon)
GTX 660Ti
P8Z77-V LX
2xCorsair Dominator 4gb DDR3 @ 1600
128GB Corsair Force Series GS
WD 1TB Caviar Black

I'm not so sure about the PSU tho, I've done online tests and all that and still I can't decide.
Any suggestions ? What are the main things to look after in a PSU ?

Hi triscuit,
The efficiency, whether it is 80 plus,
Whether it is a 20 or 24 pin connector, most have both so I'd try for that.
Get a quality name, I'd much rather have a 600W Corsair than a 1000W unbranded. Good brands will ensure quality.
And finally, the wattage. Entry level seems about 500W to 600w, but for your system I'd maybe push for 700W. This will give you more headroom for future upgrades.
That's about it :) 

Regards,
Dan.

Hi - you only need a quality 450w psu for that system. If you want xtra headroom
then maybe get a 550w, but don't waste $$ on a 700w psu unless you
plan to SLI (2 gpu's) soon.

Do buy a quality brand: Seasonic, XFX, Antec, most Corsair's, PC Power & Cooling,
Enermax, Rosewill Capstone series & some others.

Yeah you're right I did get a bit PSU happy with the 700W suggestion, I think the better quality PSU's seem to go up in hundreds, maybe a 600W Corsair? That'd still handle 2 in SLI or Crossfire, just...

Actually, my obsrvations so far are the better quality, i.e. Enthusiast
& Pro series are generally the in betweens 550,650 ,etc.
But there are good n bad at all watts.

There's no harm in 700w, just a much bigger up front cost.
I chose that route myself, needed 450w, got 650w.

more than enough, so good to go.

Yeah, maybe, just got to shop around and look at the reviews no matter what the wattage :)

So this should be enough ?

It's enough
Would be enough for SLI, just doesn't have the needed connectors
It's also considered a budget grade power supply
For the same money upfront you can get a higher quality, lower wattage , higher efficiency, modular power supply that you'll likely never put a 50% load on
