Help with correcting first build

You are better off getting 2x8 gb of ram over 4x4gb of ram.

Also do yourself a favor and ditch the wifi. Hardwired Ethernet is far better but if that is just not a possibility then powerline adapter is the next best thing. A 500mbps powerline adapter will give you 70-80mbps real world speed which is better then 300mbps wifi and will have much better ping/latency over wifi which is more important then speed for gaming.

Change the power supply as advised

Just a few minor changes on this I firstly recommend going for a 2x8 gig kit of ram, so you could leave room in case you ever wanted to go up to 32 gb of ram. I also recommend getting this XFX XTR psu over the Corsair. A lot of the Corsair psu's have come out with junky or faulty capacitors, and they often fail, which can lead to a heap of problems and trouble. Other than that, this should be a really awesome future proof rig.
 
Solution


Completely agree with this build, +1
 


Thank you sir. I think most of us will agree, I just kind of put it together based on recommendations and my experiences. XFX makes some amazing PSU'S, and sells them on the low price. I quite enjoy them and haven't seen them light anything on fire (looking at you Corsair).
 


I've heard rave reviews of them but personally never used them. I personally use a SS-1000w from Seasonic and as they're both made by Seasonic I have no complaint!
 


If you ever want to know more about PSU's, ,talk to Tiny Voices about them. He's helped me in my search of never ending knowledge. Seasonic is definitely the top manufacturer for PSU's
 


+1 for this rig!
