Just finished up building my 9070 XT build
Using some parts from my old build and new ones
Decided to build everything together then try it out when I should have turned it on and every possible build step
So when I turn it on now I get no display via my monitor, this is including the motherboard hdmi port which would say at least something even without iGPU
the hard drives are make noises, the CPU fan is spinning but the GPU fan isn't spinning

Just finished up building my 9070 XT build
Using some parts from my old build ...
Are there any starte lights on the motherboard that are on like something red or Yellow or white?
Did you only install the gpu and nothing else?

Corsair CX-750F RGB 750w PSU
There is a orange light on the motherboard but I'm guessing it's just colour scheme on it rather than error code
My motherboard is Aorus x570 Elite Rev 1.0

I did look through the manual and the light isn't referenced as an error code
I could try a speaker
I think I have one

Did it work before the gpu upgrade?
mild wraith
This is a different motherboard
Like CPU is different
Memory is the same
Psu is the same
GPU is different
hollow beacon
You forgot to update the bios
hollow beacon
To the latest?
mild wraith
Waited until the orange light went off for the bios update
hollow beacon
Did the parts work before you changed the gpu?

So I tried a different motherboard
Thinking that might be the issue
And it hangs on VGA I can tell now since this one has colour LEDs
But that doesn't make much sense
Ah okay

I mean, gpus, especially brand new ones like the 90 series, are going to have issues. Especially being first iteration.
So long as you made sure all the cables are plugged in properly, and gpu is inserted properly.... if that still doesn't work, try another gpu and see if it boots up. If it does, you know the gpu is faulty.
hollow beacon
So I tried a different motherboard
did you try putting only the gpu into another pc
hollow beacon
I mean, gpus, especially brand new ones like the 90 series, are going to have is...
mmmm i think there might be a bigger chance for a bad riser here
round mirage
Could be that too, but swapping gpus "should" tell us one way or another

This is why I love having multiple components I've collected over the years, so I can test stuff lol
hollow beacon
well i have like 30 computers
so testing is not hard for me'
if i get broken stuff i just put it in like 4 computers to test
round mirage
Pretty much. Between my buddy always giving me stuff, and stuff I bought over the years. Kinda in the same boat. The amount of totes I have filled with stuff drives me nuts at times.

So I found a post on Reddit that explained what I think is happening @round mirage @hollow beacon
hollow beacon
o boy
mild wraith
Basically I need 3x8 pin for the GPU to turn on, instead of just 8x2, I was thinking the gpu got power from the pcie slot as well but it doesn't
I need either directly 12 pin cable or 3x8 pin
I only have 2x8 pin on my PSU so I need to order another cable

does it not have a pigtail?

Pigtail?

is there not more in the PSU box

I bought it used like 1 year ago don't think it came with anything else

Yeah like I might have gotten another cable like the box says it should be 2x6+2 but I don't remember getting it
soft raptor
You need more than 2 PCIe connections for a 12vhwpr adapter. Had this last week and once someone used an additional cable it turned on fine.

soft raptor
Not sure why as in theory, you’ve got more than enough power. Must be a limitation on how 12vhwpr takes its power through an adapter
round mirage
I have a seasonic psu, bought the 4080 when it came out. They "said" their 12vhwpr which is a 2- 3 pcie cable would be enough .... it was not
soft raptor
I guess choosing a card with 12vhwpr instead of PCIe for an AMD card was a bad choice
Although I guess you’d still need a new cable anyway as this gpu would be a minimum 3 pin connection

he has 2/4 pcie/cpu plugs but each cable from the psu can do 300w
while 6+2 is only rated for 150

This should be fine correct?
I just have a gut feeling it isn't gonna work cause it's two 8 pins to 12, which is basically the same as the adapter unless I'm missing something
soft raptor
while 6+2 is only rated for 150
I thought the pigtail was 150w per connector. So 300w per cable to the PSU?
I never pigtail but genuinely curious now if I misunderstand or not.
hollow beacon
the plug itself is rated for 150w but the cable can be anything you want
well not something that cant do those 150w
so most tend to do cables that can do 300w and just use pigtails
soft raptor
Makes sense. I thought I had a big misunderstanding there.

Makes sense. I thought I had a big misunderstanding there.
Same outcome, different way of getting there lol

Wanted to give an update i ordered an 8 pin cable yesterday and it arrived today so using the adapter
Everything works now, thanks for the help everyone
