Question for PSU and Graphic update.

[coldbun]

HI,
I am trying to rebuild a new pc because my old one is 5 years old

I have a 16G DDR3 1333MHz RAM

I am currently getting a new PSU and this is what I am getting

EVGA SuperNOVA 650 G1 80 Plus Gold Certified Power Supply, Intel 4th Gen CPU Certified 10 Year Warranty (120-G1-0650-XR) for $95. Now the question is

1) I saw some forum mention that G2 is far more superior but didn't explain the differences. because the G2 is about $30 extra, does it even worth it for me to get the G2 version if I am not planning to do dual graphic card? Would they make a huge difference?

2) The G2 is single rail 12V and G1 is 4 rail, is there any big difference in term of performances?

3) The label say that it is intel 4th Gen certified , does that mean it only compatible with Intel motherboard? or It can be used on AMD motherboard as well?

4) I am looking for a decent graphic card for my the CPU, I just need medium setting with decent fps for online game and not too high end. What are the suggestions?

Please give me some recommendation, thanks.

Hello... 4) Here is a general performance price and chart... http://www.videocardbenchmark.net/high_end_gpus.html
3) They will work on both MB's

If by G1 you mean NEX650G, then that is only a tier three unit (mainly due to loose voltage regulation) while the G2 is tier one.

Between single and multiple rails, the difference in most units is simply the over-current protection. Splitting the total output current between multiple over-current protection circuits means you are less likely to burn the wiring in case of a short.

4th-gen certification means the PSU is able to deal with the load transients from Haswell's deep-sleep states, which enables higher power efficiency under light loads.

As for a decent GPU for your CPU, it would help to know what the CPU and budget are. If you do not particularly care about high-end gaming, then a 750Ti would be a nice starting point.
