XFX XTR Series 550W
Before I order. Will this PSU work with, MSI GeForce GTX 970
I have everything in my build but PSU & GPU
It will work, but go bigger... I assume you may oc eventually, and 550w is really a bit too close for comfort.
I may. But never overclocked before. Would 650W be plenty? But not to much in the meantime.
650w is the sweet spot for an i5 and a 970. Honestly 550w will probably be fine too. In real world tests, a system with an i5 and 970 only draws about 300-350w from the wall.
I agree. That's a sweet spot. It allows good overhead
I'm going into brain overload!!! Everyone has a different answer. Some recommend 750w while others 500w. So much research can't seem to make a decision. OK if I go with 650w a reputable brand. (EVGA) I will be fine. I don't plan on overclocking, never have before. To scared to plus I don't want to melt my investment.
Yeah sorry about that... This site is full of people who will give you conflicting info, but an EVGA 650w is a good choice. I have one in my system and it is rock stable.

I did that, but it does not have i5 4690k. So I put in i5 4670k. No overclock. Minimum power wattage 359. Recommended wattage 409.
I guess 450w would be sufficient?
The estimate tells you what it will likely use, not the size to get. Never cut it too close. 750w would be great for a sli setup with those gpus or with a high end amd card. The new Nvidia cards are not as greedy though. A 550w will work as I said, but a 650w allows better overhead which allows for cooler psu temps, more longevity, less noise, and better efficiency which shows up in your electric bill. Plus you'll be able to add more parts and oc if you want to later on. The power supply has the potential to take out other parts if it fails, so don't cheap out on it.
Your configuration is good.
That XFX 550W has 45Amps and 540w on +12 rails and it's SLI and Crossfire certified it can power two GTX 980s with a i7-3960X Extreme OCed to 4.6Ghz a CPU which is more power hungry than your 4690k.
