I'm upgrading from a asus maximus vii hero, i5 4690k, ddr3 ram. upgrading to a asus maximus viii hero motherboard, i5 7600k, ddr4 ram 3000 mhz. right now I'm using a corsair cx600m power supply, thinking of installing my new rosewill hive 750 watt modular power supply. which power supply should I use for the upgrade?
