[SOLVED] PSU for my computer!

[maxzzzz]

Hi, I am building my new PC but I met some problem about power supply.
This is what I got so far: i9-9900k, GTX 1080, MSI MPG Z390 motherboard, 2*8G ddr4, 2tb ssd, 144hz 24.
At first I bought corsair HX750 but somehow I cant connect it to my motherboard.
the motherboard need a 8+4 joint which is not include in my power supply box.
So I thought its just because 8+4 is only for higher power supply and planning to buy a 1000w.
But after I did some research, most people online says 750 or 850 are enough even for OC.
Now I am really confused, is it bc my PSU or my motherboard?

MSI makes several MPG Z390 motherboards. You need to clarify which one you're looking at.

On the box, it says MSI MPG Z390 Gaming Edge AC

750W is fine, a good quality 750W like:

Seasonic Focus Plus
EVGA G2 or G3
Corsair RMX

Ok. I'm about 95% certain than you only need to connect one of the CPU power connectors; not both. If your power supply has the 8-pin CPU Power (or more likely 4+4 pin), you'll just need to connect that to the 8-pin CPU_PWR1. CPU_PWR2 will remain empty.

Given your build, just about any quality 650 watt PSU would be sufficient. I like (and have) the Seasonic Focus Gold 650.

On the other hand, if your power supply only has a 4-pin CPU Power cable, you would connect that to CPU_PWR2 and CPU_PWR1 would remain empty.
