hey, tomorrow I am going to buy some parts for a build that I am planning.
The problem is that they don't currently have a good 750W PSU for a reasonable price, so I have to chose between RMx 650W and RMx 850W (with a 15$ extra for the latter).
which should I go for in your opinion? would the 650W be enough? should I wait for 750W?
 

tldr: RMx 650W or RMx 850W for this build?

Even the RM550X would be more than enough.

The only reason to consider the RM850X is because it stays quieter for longer.

You can never be:

(1) Too rich

(2) Too thin

(3) Too well armed

(4) Have too much power.

 

Extra wattage leaves room for upgrades.

Also look up the efficiency of the PSU usually they are most efficient at 50% load.

No problem, I have the 750W version great PSU probably 90% of the time the fan doesn't spin on mine and it feels cool to the touch ect. Plus that 10 year warranty! 

Should be your last PSU for 10 years.
