Corsair ^ Not quite as good but near your budget + $10 extra dollars off w/ promo code EMCXRTW22, ends 6/6
 
+1 SR-71 Blackbird.

Corsair is a reliable PSU manufacturer. The CX models are quality PSU. But they are not fit for your system. They are meant for basic, not high performance, builds. Your build does not qualify. Just like how you work with compatibility with your other components in your system, you also have to address the PSU. And the PSU Is the most important component in your entire build. It is connected to every other component and must supply power to them all.
