So I'd change that to a single rail unless you are expert on the topic of rails, amperes and balancing. Even the the 24A rail may be too easy to overtax so change that.
I am looking at building a new computer and would like some honest advice at how sound this is. I am looking at only doing some mid-range gaming to minor older games but would like an open door to possibilities of maybe down the line of ability to add upgrades as i see fit. I do a lot of music uploading and love tinker/dabbling with downloads of all sorts. I am into the idea of windows 10 wanting away from windows 8.1 not wanting to go backwards on the operating system but forward. Are the parts I have posted of good nature or is there any suggestions? I have only got $850 and want to have a good pc but not huge. I base most of my purchases more on ratings and some on technical but would like just simple advice(still new to building computers), are these parts good enough for each other or should I change them? I am not gonna steer away from the case so don't try and change my mind on it please. All parts are found on Newegg.com.
