hi guys
recently i bought asus b460m prime and intel i3 10100f
my psu have just one 4 pin cable for cpu
but mobo have just one 8 pin input
so i decide to test that 4 pin cable..
But after turning on the pc
I did not receive any screen
There is no mention in mobo manual file about using just one 4 pin
======
so my question is that :
is 8 pin required for booting up this mobo ?
or maybe something else is wrong ?
(my language is very bad ,srry for that)

I am sorry to inform you that you cannot connect 4 pins to connect to mob. You need a 8 pins from PSU to do so.

tnx
but are you sure ?
because there is alot of posts and content on internet that says 'yes you can'
what you said is about this specific motherboard or asus motherboards ?

I am referring to to the mobo that you use for Intel 10100f. For my understanding that intel series mobo support 8 pins If my memories did not failed me.

tnx alot
so what you said means :
yes we can use 4 pin cable in 8 pin mobos(because people on internet said they did it before)
but thats not works for this motherboard and this motherboard need 8 pin ?

In short your mobo need 8 pins connector from your PSU to your mobo and 4 pins will never work.

If 8 pin is enough to handle 190W CPU (12700), 4 pin should be enough to run 95W CPU, right? Actually 4 pins are rated to handle up to 105W. Yours require 65W and peaks up to 90W.

I say it should be fine.

in old motherboard yes that works fine
but about new motherboard there is different answers
some one say "yes" some one say "no"
I wonder why nothing is written about it in the manual file

But there is nothing special behind EPS cable - all pins are just +12v and a ground. It's all about how much load can it take. If 4 pin cable is rated for 105W and his CPU requires 90W the most then he should be fine with just 4 pins.
