I got a Asus X570 ATX motherboard it has a standard 24 Volt EPS power connecter plus looks like a 12 V CPU atx power connecter and I do not have this connection on my power supply, do I just get a converter ? Molex to cpu 12 volt converter? And call it a day ?
I would like to know how important that is ?
It is a supplementary? I am not going to over clock it. Right now I am Using 2700 (non XCPU ) and future I would upgrade to 57000X. I do not have any plans for overclockimg. I am looking for CPU the stability and longevity.
CPU/Chipset do memory (XMP) over clocking and factory 🏭 self CPU boost.
Thanks

Does it boot w/o it connected? Normally I try to connect all power leads that are available on the MOBO for the sake of having not to go back and do it again later. They're usually in difficult positions to get to post-install.

It could be a performance impact later on with additional power needed foe a specific CPU model other than your current one. Upgrading the PSU to something that does have the proper leads might be a consideration worth investing in.

I use Intel but, EVGA PSU's have all the proper leads for almost any board. For $100 it's worth the protection and knowing you're not leaving open power receptacles on the MOBO that could provide more power when needed.

Looking at the MOBO itself to the left you see the indicators for EATX12V_! & _2 there should be something in the manual indicating whether it's optional or not.

Not sure what the purpose is as they're not indicating Voltage for the pins. I suspect this is for some sort of accessory power need. Maybe a few extra Watts of power for OC'ing the system?

Looking at my PSU configuration there's 2 x 8pin CPU connectors broken into 4+4 on the ends to accommodate the 4 pin connector.

That extra power connectors are 12 volt. Probably for extra power demand for cpu.
System boots up with extra 12 volt connector
Right now it is using EPS 12 volt for the CPu.
I will get a molex convertor 12 to atx 12 cpu connector and called a day.
P.S. have enough amps to support my CPU needs
Thanks

So I have order it the 12 volt CPU Atx connector (P4 era lives again)
Hopefully it will able pump all extra voltage to PBO pwr schema.
Let see what sort benefit 65 TDP will get out of it.

My new Asus Z690 has the same extra 4 pin connector looks like yours which I left it alone. The system operates just perfectly fine without it. My cpu is i5-12600k Alder Lake .
Exactly, most CPUs don't need it. I never use it on any of my boards. But I haven't run Intel beyond 10400, and AMD beyond 5800x on the boards. The 5800x runs 5050MHz with 88W power package limits, so not exactly needing the extra juice.

I don't use that connector, only the 8 pin one.

That extra one is for high current draw CPUs like 5950X or serious overclocking.

I got this connector.
If the load is distributed off this connectors to different vrm / rectifier(s), then it will be evenly available.
Or tomorrow if we I get a cpu for this future dead AM4 socket, I have a power to the MB.
Or I lost the $6 bucks ;)
