Power Supply is acting up

[ultragab22]

here is my setup.
AMD FX(tm)-8350 Eight Core Processor 4.34
with 16GB of ram
64 bit operating system
I have a 750W power supply
an asus GTX 760
a sabertooth 990FX R2.0
an i have a wifi card from asus
and 1tb seagate hard drive and one samsung 500gb ssd
I get a whea uncorrectable error Im pretty sure its my power supply but what do you guys think
This usually happens when im playing fallout 4 and things of that genre
it just freezes and shuts down
