An alternative would be to buy a very low end graphics card purely so you can test the system and make sure it works properly...won't be playing games on it but could be used to rule the new GPU in or out. You can get an NVIDIA 710 for just over £30:

MSI NVIDIA GEFORCE GT 710 1GD3H LP Graphics Card '1GB DDR3, 954MHz, Low Profile, Low Consumption, VGA, DVI-D, HDMI, HTPC, Silent Passive Fanless Cooling System': Amazon.co.uk: Computers & Accessories

Personally that is best option, as the OP needs to factually confirm what is working and what is not.

for the outlay it’s money well spent.

It's entirely possible you have received a GPU DOA or have caused a failure in it with something being shorted at some point. If you had any access to a known good GPU this would help narrow down where the failure is.

This!

My concern is your GPU is dead.
It should definitely boot to Windows with a 650W power supply. Nvidia recommend a 750W power supply based on the total power draw of the card.
Your card should not be pulling any where near total draw on boot.

The fact your mobo isn't giving you a GPU error code when trying to boot with it plugged in is confusing though.

*edit* clear up confusion.

@ChaLow Did you try running the GPU in your second PCI-e slot.

For convention the way you have the card set up in the top slot is correct but if you try the bottom slot it will ilimanate the possibility of the top slot being U/S.

Nothing happening in the bottom slot either i'm afraid.

So it's not possible for this to be a power supply issue? I'm thinking that even if I try this £30 GPU, perhaps it could still be that the PSU is just not handling the 3080 due a fault.

Its still a possibility that its a PSU fault but as you can boot without the GPU inserted its not likely. Once you get the new GPU we can start ruling stuff out.

fix one issue at a time.
confirm no other issues first.
avoid speculating until you know some more facts.

Anything is possible...but it would be a very strange fault. The GPU draws very little power from the PSU during Windows bootup and general stuff as it only needs enough to display Windows...as an example, my 2060 Super is currently running at between 0 and 5% with a single Firefox tab open. As I said, anything is possible but I would, in my slightly less than expert mind, be very surprised if it was a PSU fault
Click to expand...
Right. I suppose I'm talking about the PCIE outputs on the PSU being faulty, not so much it's ability to supply power overall.

Fair enough...I didn't even consider that. Still, if they are faulty then it will likely show up with the 710. Anyway, we are just speculating and guessing here...let's see where you are after trying the 710 and go from there. If it turns out to be a faulty PSU, PCS are very good at replacing them (I phoned at 9am and a new PSU arrived just after 1pm the following day)

You're right, all I can do is wait until tomorrow. I need to take my mind of this for a while anyway. Thank you for your help.

Ok, this is just a thought, as it boots without the GPU, have you tried to clear the CMOS/BIOS/UEFI?

Remove the power cable that pugs in to the wall, remove the GPU, then on the bord, there is a CMOS battery, remove that and then turn on the PSU stitch and off about 5 times WITHOUT THE POWER CABLE IN IT THAT COMES FROM THE WALL then press the front pannle power switch in and out 5 times, this is done to try and discharge the companents and help clear the CMOS/BIOS/UEFI, then place the CMOS battery back in, reinstall the GPU adding power to it and try switching the computer on again, see if it is still the same. also put the wall power cable in :)

I tried clearing the CMOS, to no avail. Anyway, the new £30 GPU arrives and the computer turns on just fine! So what should I make of this? Sure, the 3080 being broken is definitely a possibility, but the PCIE cables and weak PSU are still culprits. My new 850w PSU just arrived, so should I give that a go?

Ah, sorry clearing the CMOS didn't help, I really do hope it's just the PSU, I have my fingers crossed for you :)

I've replaced the PSU and still nothing, so it's definitely the GPU. It's fine! Luckily I also ordered an MSI Ventus 3x OC from Scan and it should be here in a couple of weeks. So we can consider this problem to be solved, at least for now. Do you reckon it's worth trying the PCIE cables that came with the new PSU? I used the ones that came with the 650w.

Thank you for your help everyone.

This must be the most chill reaction to discovering you're brand new 3080 is scrap! Haha.

Doesn't help to dwell on these things. Plus the seller has accepted the return and have suggested it was dead on arrival. I won't argue that! I also tried the new cables and there was no difference.

sorry to hear that, but at least you have a new card coming in a few weeks
