What I can't understand is one is $63 cheaper but offers and extra 50w...

What one would you guys recommend? I want to use the PC to play games like Dayz and Bf4 by the way.

The more expensive, lower-wattage power supply is more efficient.

What is the rest of the hardware in your computer?

what is your complete system spec..?

you won't need a 700 or 750 watt psu except you're using multi graphic card and super highend parts inside your computer case..

well, then why the price difference between both psu is huge?
the 750 watt naxn psu is a bronze efficiency PSU..
and 700 watt naxn is a gold efficiency psu..

all component of 700 watt gold naxn using much higher quality, better psu design, and very durable compared to 750w bronze..

That's why this unit more pricey than the other...

I also plan to buy a second 7850 and crossfire it in the future

Quaddro · Dec 7, 2013

well..let's see..

a system equipped with hd 7850 only consume less than 290w while gaming..and less than 320 watt when you overclocked that card..
please note, this is total power consumption for all computer parts

there's no need 700w power..
even a 430 watt power supply will serve you very well..and still have plenty headroom..

but if you want to add some extra headroom, then a 500w good psu will an excellent for your system..

okay, crossfire setup..
then let's see..

still less than 500w..

even with a seasonic 520 your system will run flawlessly..

but if you want to add more headroom, then a good psu with 600-650 wattage power will serve you well..
