Help With Build CPU Power and Motherboard

BMovieExplosion · 24 Oct 2012 at 16:01

Hey everyone,

I'm currently in the middle of my first build and am slightly stuck in regards to the psu and the motherboard. My psu has a 8 pin connector and is clearly labelled for cpu power, however my motherboard has only a 4 pin receiver. The cable fits fine, I was just wondering if this ok.
It's a Gigabyte Z77-D3H and a Corsair TX 550M.

Thanks!

The 8pin splits in half to make two 4pins? only one of these four pin will fit in to the motherboard.

Yeah basically half of the pins fit. They fit fine in the mother board, just with four on the side connected to nothing. I haven't booted yet, will it be ok?

Thats fine.

Just tried booting. Everything worked but no boot. I suspect I need an adaptor.

An adapter for what?

BMovieExplosion · 24 Oct 2012 at 16:56

8 pin to a 4 pin. Unless I have done something else wrong.

stulid · 24 Oct 2012 at 17:04

You only need to fit one half of the 8pin ATX connector into the motherboards 4pin ATX socket. The pins on the two halves have a different shape, so only one half will fit.

You've most likely done something else wrong.

Instead of me trying to guess, can you list EVERYTHING that makes up the parts list of this PC.

I appreciate the help. I used a pretty in depth guide to build. I read I'm supposed to hear a beep but I'm not.

Remove the GFX card (you have tried with both PCI-E power cables into it?)

Plug the monitor directly into the motherboard.

Is there now a display?

BMovieExplosion · 24 Oct 2012 at 17:15

Yes I did have both PCI plugged in. Took it out.
Yes I have a display now!

Update the board BIOS.

get the latest from Gigabyte UK website.

Extract the file onto a USB thumb drive.

Enter the BIOS and click on Qflash.

Follow the simple instructions.

BMovieExplosion · 24 Oct 2012 at 17:25

I'm afraid I don't have Flash Drive right now.

Is there any other way to get around this?

I have a disk that came with my motherboard, not sure how much use that is...

Can install windows and configure the GFX card later?

stulid · 24 Oct 2012 at 19:42

You can do.

Or you could try using @BIOS from the desktop (but Qflash is the recommended way)

Hey. Thanks for the help! It's ok I figured out you can't first boot using hdmi so I had to root round for my other cables.
Thanks again guys.
