I am consider Corsair
RMx Series™ RM750x , is it good?
I considered this before but i went for RM750 instead due to cheaper cost, plus both are backed with the 10 years warranty and performed almost the same based on many reviews i read or watch online. You can consider if the japanese-made caps and higher quality fans of RM750x are worth the $40-50 difference compared to RM750.
