I bought a toughpower grand rgb 750w gold full modular power supply and then I found out that my gigabyte z390 motherboard needs 0ne 8 plug and one 4 plug eps. So I see that the 850 has the two plugs but my power use is way below the 750 so it is fine. Is there a way to get another cord that plugs into the pci-e slot and has a 4+4 to atx eps on motherboard it looks to me the 4+4 cpu and pci-e are the same.
