Which is power suplly should i buy 650W or 750W

[HHHH]

Core i7 8700k over clock to 4.8GHZ
ASUS ROG STRIX Z370-F Gaming
AssassinII CPU cooler
Corsair LPX 3000MHZ 16GB 8x2
GTX1070ti
Samsung evo850 250W
WB Black 1TB
Corsair Crystal 460X with 4 fan

 

how much watt power supply i need
PS: In Corsair which power supply should i buy CS,CX,RM,TX or other there line up is very confusing

In my country there are only 3 brands for power supply Corsair Cooler Master and Thermaltek

550-650W is plenty. The Corsair RMx is their reasonably priced really quiet PSU.

The RM or TX would be good for your system.

 

Have you actually overclocked your CPU yet? 4.8GHz might require more cooling than your CPU cooler is capable of.

I'm just saying, binning dictates how well your chip will be able to hit clock speeds that high, so it may require 1.4V to get that high, it may require 1.25V - you won't know until you try. 

 

Anyways, the 550W version of the TXM and RMx are fine.
