English is not my native language so if I write wrong, sorry.

My setup is (yes, is an old setup) :

Intel i5 4670K
Gigabyte - GA-Z97X-UD3H
Kingston - HyperX 8GB (2 x 4GB) DDR3-1600 Memory
MSI - GeForce GTX 1060 6GB 6GB GAMING X
WD Black 1TB
Coolermaster 212 evo
Case Haf 912

My actual PSU rip, so:
I was going to buy a Seasonic 620 M12ii Evo 80 plus bronze. (I really like modular psu)
But the Seasonic 750W M12ii Evo 80 plus bronze is on sale offer at the store where i usually buy.

1. Is worth to buy a 750W instead of 620W for a lower price? (Yes, i know with 620W should be more than fine. Idk, maybe for a future use)

Now the ram issue:
I know that the RAM uses 1.65V and Haswell CPU uses 1.5V (But i didn't know it when i bought them)

2. What % affects?

3. Is worth replace the actual RAM?

4. In case i want to buy more ram, which option should i choose?
a) 2x4gb
b) 1x8gb
c) 2x8gb (if question 2 is yes)

5. The voltage of all the RAM need to match? (i mean, old-new RAM)

 
Solution
Getting a 620W or 750W PSU is pretty pointless since your rig will not draw much over 200W when gaming. What are the actual prices of these PSUs?

Also, not sure what your RAM concern is. DDR3 RAM is normal to use with Haswell. It's Skylake you are thinking of that has a different voltage, so no worries there.

I live in Latin America, because of taxes and blabla, the prices are:
620W 154uss seasonic store
750W 185uss seasonic store
750W 164uss other store 17%off

the difference is 10uss, nothing.

I already know that maybe with a 520W i will be fine too. But modular is modular.

But yes, you are right. Is a waste of energy buy a 750W psu just for the price.
