Well superflower makes the Malin components for EVGA but EVGA makes modifcations to improve performance and Seasonic are really good making PSUs but if we are talking 150 $ range nothing comes close to EVGA SuperNOVA P2 750W platinum or titanium rated EVGA PSU´s is unmatched in performance its not fair to compare the GQ series PSU´s with Seasonic premium models but P2 or T2 series from EVGA is probably best PSUs on the market and it comes with a 10 year warranty defently my recommendation 96 to 98 % accurate power supply across the board its about 150 $
I didn't compare Seasonic PRIME series to the EVGA GQ series. I just suggested a great PSU to go with. You sound like an EVGA fanboy by stating such a thing.
Still, let's see how EVGA 750W P2 PSU stands up against PRIME 650 80+ Titanium and if it really is better as you say it is.
Since EVGA 750 T2 does cost more than $150, i won't include it to this comparison,

While both PSUs are great units, Seasonic unit is a bit better. For an average consumer, the ripple noise, hold-up time and voltage regulation usually doesn't matter. What matters is the noise output and warranty length. And for some, efficiency too.
