I'm planning to buy the "Seasonic Focus GM-750 GOLD" which is currently $110.00 in my country. I need to replace my aging "seasonic s12ii" which I purchased last December of 2015.

Here's the story:
I got a whole new system, i3 10105f with 6600XT and I noticed that the screen would freeze and the GPU would spin it's fans at the maximum speed which is quite noisy. It didn't happened before when we were using the 6600XT on my other computer. We did checked everything and figured that my aging PSU needs to be replaced since both rx480 and the new 6600XT had some issues if we plugged it on the old PSU, which I am planning to replace.

The real question is the new "Seasonic Focus GM-750 GOLD" shows that it has this "ATX 12V" and I'm not sure if it will be compatible with my motherboard since after I researched about it, the website shows that it has 10 pins? I'm not sure if that would be compatible with my motherboard

My motherboard is "ASUS PRIME B560 plus"


Can someone help me by explaining it?
I also checked the website and they said that the PSU manufacturers are now adopting this ATX 12V due to intel's implementation on their 12 gen processors

ATX12V is not a new PSU format, it's been around for more than 20 years now. The newer, 10-pin connector is in ATX12VO, which removes the +3.3V and +5V rails. The PSU you list has normal connectors for an ATX12V PSU, not a 10-pin connector.

Intel's been trying to push ATX12VO, but the aftermarket companies aren't the least bit interested so far, so Intel pulled back from that for Z690.

I could see adapters making older power supply's work with 12VO since higher quality power supply's deliver most of their capacity on the 12v rail anyway and 5v and 3.3 are just dc-dc which in that case would just remain unused.
