can someone pls shed some light on this issue?

PSU Calculator input and result (I do realize some stuff are super overkill, like 24/7 usage and 100% TDP, im trying to replicate the most overload situation possible.):

thanks alot dude!
do you think Cougar GX800 is good enough?
 


No, Cougar makes low quality power supplies. Try Seasonic, Antec, XFX or EVGA B2 series.

No, I'll tell you before you list any other power supplies to ask if It's good enough; below 100 dollars, out of 500 power supplies you have only 30 good options. A bunch of them are not solid, and the ones that are good are the following brands: Seasonic, Super Flower, XFX, Antec HCG, EVGA B2/G2/GQ/GS, Corsair RM (So not CX/VS, those are bad), Be Quiet! Straight Power 10, Rosewill Capstone.
