rockie where did u get those numbers from? According to this website, it's 500W for one 970 and 700W for SLI 970s: http://www.realhardtechx.com/index_archivos/Page362.htm

Brandon, as for your build, go with 500w-550w, it doesn't matter just remember that more wattage is not always better.

Here are my suggestions:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151094&cm_re=520w-_-17-151-094-_-Product
http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013&cm_re=xfx_ts_550w-_-17-207-013-_-Product
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182068&cm_re=capstone_550-_-17-182-068-_-Product

All 3 of those are the best PSUs u can find for that wattage range, choose which u like the best they are all high...

The case has a fan controller on the top. I was wondering if you took that into consideration with all the fans hooked up, I plan on putting 1 or 2 more fans inside as I have some fans laying around. Great Feedback I appreciate it.

Don't worry about fans and stuff, the people at realhardtech calculate the wattage amount for the cards thru extremewattage calculator and add like around 150w headroom which is plenty for OCing and fans or whatever :p that's why I would advise not going above 550w cuz at that point you're already getting 200W headroom :)

That site is great for a rough estimate. It is much more accurate to add up each component's thermal design power (TDP). I usually just take the CPU and GPU as they are what can vary by so much, then add 100W for a typical system, then add 100-150W for overhead for overclocking and/or just to give the PSU a bit of breathing room so it's not working too hard to power everything while gaming.

So in this case:
i7-4790K TDP: 88 W
Asus Strix GTX 970 TDP 145W
Rest of system 100W

So without overhead, the system at full draw is asking for 333W or so. If we add the 150W for overhead we're sitting at around 483W. So yeah, a 500-550W PSU would be a great choice for this build.

Brandon, go for semi-modular, it's the perfect balance between modular and non modular. It has the cables u want on it and the ones u don't off it, so go for that. Modular costs more money usually and isn't relly worth it for most people.
