Is my build not powering on because of a 12pin cpu?

Recommended Posts

Posted · Original PosterOP

Hi,


I am currently building a pc and when I tried first power on nothing happened ;(, so I did the usual thing and checked on the cables to make sure nothing was loose until I noticed that my motherboard( Asus rog strix x570-e) had a 12pin cpu connector instead of the standard 4 or 8 in most other builds I’ve seen, so I’m wondering if that is the reason my pc isn’t powering on.

 

Any advice is greatly appreciated,

thanks.

No, a 8pin can provide 384w of Power.

My words of advice:

Don't buy Cherry Browns.

Don't play Overwatch. I've hate the game yet I play it every day.

Wireless > Lighter Mice

Silence > Temps for Coolers

Get a good PSU

You can try, but it shouldn't be it. My 3700X runs perfectly with an 8-pin only, even though I've got the 4-pin as well.

The extra 4 pin is not needed, so that can't be the culprit.

What do you mean 'nothing happened'?

 

No lights, beeps, fan startup, etc.?

Are you sure the PSU is turned on? Can you try to start the system by shorting the motherboard pwr button pins with a screwdriver?

No, the extra 4-pin is totally unnecessary.

 

The RGB LED on that ROG logo should be on (even with the system on standby), or at least that's what it's like on my Strix Z390 board.

Have you checked whether the 24-pin and other cables are plugged in correctly, both on the motherboard side and on the PSU side, and is the PSU actually turned on and plugged into the wall right?

Hi, what I mean by nothing happened is that no fans or anything turned on I’ll try that now I’ll just need to find it.

What is the Q code LED showing? (bottom left)

 

Good job, one fan isn't wired up to spin though.

Yah the vertical mount got in the way of the fan but I sorted that so it’s spinning now
