I buy a 970 (which only has a 500w recommendation), while planning on buying another 970 to SLI within a year? since the 970 SLI has a recommended PSU wattage of 700w.

Sure, why not. Just check if it has the right plugs for both GPU's (I think you have to do that)

Also, just be sure it's a good PSU (Power efficient and form a reputable brand)

That would be fine. Peak power consumption for my system with dual GTX 970s is around 600W, so you will be good.

It doesn't matter, as long as you have over the needed amount you'll be fine. You don't really need a 700w for 970 sli, but it is a decent wattage for it. What PSU are you planning on getting? Some will be a lot better than others with similar looking specs.

may I ask what you do with your PC that probably cranks up the power consumption of your 970 SLI?

Whoops, should have clarified, I have a single card. I know for fact though that power consumption of an SLI system with my components would be around 600W.

the perfrect PSU for SLI 970 or 980 is the EVGA 750 G2, look no further, very good and reliable and efficient PSU

I based my choice of PSU from this http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html which I saw from another post here in the forums

from that I found that the cheapest PSU that they sell here in the Philippines, that also falls under tier 1 were from the Seasonic M12II series, with a choice from 520w (for single 970 use), 620w, or 750w (both could possibly power a dual 970 SLI, although as recommended by others, the breathing room that the 750w gives is probably better)

awesome! I'm still about to build my PC and I'm also gonna use the Air 540, although I'm gonna get a 4690k instead of a 4790k. can I ask what you use your PC for? do you do some video editing or just normal stuff and gaming?

Mostly Photoshop and gaming, and it does very well. The Air 540 is a really nice choice for a case, the layout makes it incredibly easy to build and cable manage.
