I'm looking to pair the SuperNOVA G3 550 with an i5-9600K and Gigabyte - Z390 AORUS MASTER.

My understanding is that the CPU will max out at 130W under normal use and a single 8-pin EPS maxes at 336 watts. This makes me wonder why I would need to plug-in 2 8-pin EPS cables even when overclocking this CPU.

Long story short, my PSU only has 1 8-pin CPU connector. Will I be OK to only plug 1 into this motherboard?
