Pcie pins for Power supply and GPU my discord#4721

[Amjad07]

Hi, basically I need help with what pci cables I need to power my GPU.

My GPU is a Gigabyte windforce 5700xt which needs a 6pin and 8pin. Psu is a Corsair vengeance 650w silver

What cable do I need for the GPU (one or two separate)

And how many pins do I need for the cable that goes to my psu if it is just one cable (6 pin or 8 pin)

(Side note I’m new with this and have other questions as well, can you get one cable that has a 8pin (6+2 pin ) and one that’s just a 6 pin with the other end going to your psu or do both have to be 8pins if so do you leave 2 pins dangling?)

Can you recommend any cables that are suitable for my graphics card and psu please.

 

[Amjad07]

So my PC has just came but there are two 8 pin connectors that come from the psu (ones that you can’t pull off) are they for my GPU or shall I just leave them there and connect a separate pci cable for my gpu?

 

[Amjad07]

No the two 8-pin that are fixed to the PSU are EPS12V connectors - 1 of which will need to go to your motherboard.

You will need to connect the separate pcie power cable that @Brizzles showed above.

So one of the 8pin will need to go my motherboard? If that is the case I already seem to have a cable connected to my motherboard which is an 8 pin only but there is 4 pins still need connecting?

 

[Amjad07]

What motherboard?

Assuming it has both an 8 pin and 4 pin on the motherboard then those 8-pin connector should split in half (4+4) - use one for required 4 pin.

Asus rog strix f gaming, well there is already one 1 8 pin connected on the top left and that’s it while I have 8 pin spare from the psu

It

Asus rog strix f gaming, well there is already one 1 8 pin connected on the top left and that’s it while I have 8 pin spare from the psu

It says on the manual that you need either 8 pin or 8+4 pin connected so I don't understand what the cables from the PSU is for

 

[Amjad07]

If there is already an 8 pin connected to the top left of the motherboard then that that is all you need for there.


For the gpu you want the cable/s that are marked 'pcie'. One end should say 'Type 4' and that plugs into the power supply. The other end which has the 6 + 2 connectors is for the gpu, so you can use it as a 6 pin (2 pins hanging down) or an 8 pin by using the extra 2 pin part.

The thing is i contacted my PC builder and he said it's fine using the cables that comes directly from the PSU now the issue is nothing turns on besides my Asus logo......

 

[Amjad07]

Check all cables are fitted firmly, they will usually 'click' when in place securely and they only fit one way.

CPU and cooler installed ?
RAM installed in correct slots ?
HDD connected ( though should post to bios without ) ?

Yep everything is connected

 

[Amjad07]

See my edit, above - could be the leads for the power switch on the case

Yeah the power button at the front doesn't do anything, feel like that's the issue but i don't know what cable that's for, everything does seem connected tho...

 

[Amjad07]

It might be a good idea to take some pictures of the connected cables/board/psu/gpu etc just in case anything sticks out.

You can use a free site like https://imgbb.com/ to host the pics and then post the link/s here.

you are looking for these leads coming from the power button area of your case ;



the one marked POWER SW is the one you want.

it connects to the bottom right part of your mobo ( consult your manual for as cleare picture )

Yeah they were already connected, still doesn't work....

 

[Amjad07]

Try unplugging the 'power switch' from the front panel header and then use a phillips screwdriver to touch the two pins. That will bypass the power button on the case. If it doesn't boot up that way then something else is amiss.

This video shows you how to do it if you are not sure.

Can you contact me on discord

 

[Amjad07]

You only need to plug in the 8 pin cpu. The other 4 pin is just for extreme overclocking, so optional for 99% of users.

You talking about the top left pins of my motherboard?

 

[Amjad07]

The power switch. It should be called 'PWRBTN' on the motherboard front panel header.

Can you help me to locate them

You have discord?

 

[Amjad07]

You have the 8 pin plugged in at the top left ? So that is ok. The other 4 pin to the left of it doesn't need a cable plugged in.

Yeah that's already commected seems like I get power but not to everything thing like I said before I get power to my RGB on my mobo

Number 14 - FPanel

You guys have discord?

Ah, its the 570 board, i've been looking at a different one.

The 570 does indeed use 2 atx leads 8pin and 4 pin ( the 2nd cable in my first image - marked CPU )

Where you have the 8pin plugged into your mobo, use the 2nd identical 8 pin, but it will split in half so you can you it as a 4 pin

EDIT : looks like your psu only has 1 x 8pin atx lead - not sure what t osuggest now

You sure cause I'm pretty sure it has 3.....
