Fall out 4 issue with PC

[ELSknutson]

About a month ago my PSU died it was an old refurbished corsair ax850w. I swapped it out with a cheep corsair cx600 I had laying around and it seemed to do the job but now when I play Fall Out 4 the computer will shut off completely durning graphically intensive spots. So I'm thinking that my system is drawing to much power and turning off becouse 600 watts is tight for my system, But let me know what you guys think the issue might be. 

 

 

PC specs: i7 5820k,  GTX Titan X, 3x 256GB SSD's , 2x 2TB HDD's, NZXT hue+, D5 Pump, CPU overclocked to 4.4Ghz 30-60C, GPU overclocked to 1580MHZ temps 35-79C.

 

also the system runs fine when in Windows and playing games like TF2

I know but I did not want to have to buy one when I had one just sitting there

Id get a 850w psu then if the issue still persists just send it back within the first 30 days and get a refund

Ya that's what I will likely do but I won't return the PSU I have an EVGA 1000wG2 picked out that should give me plenty of headroom for another Titan X if I choose to go that way.
