dropping to a 450 watt from the 550w is a 20.00 difference the 550 is 79.99 and the 450 is 59.99. As long as a 450 wont run into any issues im fine with it. I honestly dont know how much the system will use for watts so as long as 450 is more then enough then ok
the price would be 979.16 is i drop to the 450watt. my only issue is will the PSU still be good from the 8000 series when they come out. dont wan to screw myself
You could easily run a i5 4670 and 7950 off a descent 450w PSU.
I just sold my 3770k + 7950 combo and I ran that off this 500w PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817703035
Which to be honest is a pretty descent little PSU for the money, I got it on sale for $65 shipped from newegg about 7-8 months ago, I see it's currenty back up to $84 though. I even ran a GTX 680, and 7970 with the 3770k with the PSU with no problem. Well, not all the GPUs at once, those are the different GPUs I used in that system with that 500w PSU, and never had an issue, even OC'ing them slightly, which I know you don't intend to do.
