Do you need to connect both 8pin and 4pin EPS on Asus Rog Maximum XI Formula?

Hey guys,

I’ve got a question regarding my ASUS ROG MAXIMUS XI FORMULA motherboard. Is it really necessary to have the 8 pin EPS CPU cable and the 4 pin? Or will it just be fine with the single 8 pin?... Why’s there another 4 pin for really?...

Thanks,
Dawelio

OnTopic.. Have you RTFM'd?

Because of usual doucheness answer from you, the answer to your question is yes.

Of course I’ve read the f*king manual, as you plainly put it in your link, but couldn’t find a straight answer to my question. Hence me asking here... But seeing as everytime I try to ask something I can’t find an answer to on the internet, I always get an ”dummy stamp” response from you.

I ask here because this community consist of people way more experienced and knowledgeable than me. And I do have learned my lessons of doing the research I can, before asking on here.

So I’d advice you to please stop with all of the ”Was it hard to Google” it and if I’ve read the manual or not. Cause I’ve done both.

Now that that’s out of the way, anyone that could give me a clearer picture on this?...
Cause it works with the 8 pin, just not sure what the + 4 pin is really for and if it’s actually required as well or not?...
 
You don't need to connect the 4pin for standard use or some overclocking, the only time you would need that is if you where to go deep subzero overclocking, way past -150c.


Just put in the 8 pin and that will suffice.

That's my understanding also but if you have a spare cable you might as well connect it - I always do.
 
To be fair the manual should have that answer. You probably didn't see it. As for the common sense part, every board has an 8 and it's fine. Which should make you guess an extra 4 isn't needed. Even if you didn't realize that you wouldn't hurt anything by trying to boot without it. The system wouldn't boot if it needed it and you'd get an error telling you as such.

Thanks everyone for your replies, much appreciated!

To answer you NBD, what I can find in the manual regarding the EPS connectors are the following:

• DO NOT connect the 4-pin power plug only, the motherboard may overheat under heavy usage.
• Ensure to connect the 8-pin power plug, or connect both the 8-pin and 4-pin power plugs.

And to my understanding, that doesn’t specifically answers my question really... Just says in general.

The reason I ask is I’m about to order custom cables and wondering if I should/need to add that extra 4 pin or not.
 
Depends. On my FX Crosshair it was for the memory. 8 phase for the CPU and four for the RAM.


The memory might have had a 4 phase, but no memory draws that amount of power, like ever to need a 4pin on its own.


Sounds like a wicked power design :P

I'm glad you have experience with my motherboard. Because I really didn't have a clue (yes that was terribly sarcastic)

The original board used an 8+2 power phase solution and the Formula-Z uses an 8+2+2 setup

Noting, the last two phases were for the memory and got their power from the 4 pin. Without which the board would not boot.

Um.. it quite literally answers your question.
"Ensure to connect the 8-pin power plug, or connect both the 8-pin and 4-pin power plugs."

Not sure how it doesn't answer your question. It says connect the 8 pin. Or connect both. It doesn't get much more specific.
 
Like the picture in the manual shows, definitely plug in 8 pin, optionally plug in the 4 pin as well.


It's basically for very high power draw. According to this a 8 pin EPS can handle 336W.

My question is basically, why is the 4 pin there if you only (need yo) use the 8 pin? What is the function of the extra 4 pin? Is it for heavy overclocking or what?...

That is my question basically, which as far as my understanding goes, doesn’t say.

It could be for a number of things. Extra power when heavily overclocking, heavy power for overclocking RAM, etc. Best thing to do here is stop getting in such a twist and just connect it. It won't hurt any.

It will hurt my wallet :p ... As mentioned previously I’m about to order custom cables and wondering if I NEED that extra 4 pin EPS cable. As that adds another $20 to the overall cost.
 
You bought that set up and you're sweating over twenty bucks?

Loooool

I’m not sweating at all over twenty bucks. I’m just not gonna throw away money just because. And yes I bought this setup, over a long period of time, not everything at once. That doeesn’t mean I have a ton of money just because of that dude. Besides why pay for it if I’m not even gonna use it?...

He has a right, to hold back on splashing extra cash if he has emptied his account on a high end board.

Don't see why buying an expensive board means he has to lavishly overspend on other unnecessary items. £20 is still £20 saved if he keeps it in his account.
