My first PC won't turn on - HELP!

[ProEnigma]

Oh interesting! So if I'm using the 3080 FE 12 pin adapter, it would be two separate PCIE cables, one for each 8 pin? I will try this!

Yes, 2 separate 8 pin PCIE cable from the PSU to the 12 pin addapter.

I'm not sure if it will make the system boot, but as the PSU is below the recomended spec, 650W not 750W and only one cable, the GPU may not be getting enough power to show a display, this may be the reason you dont see a POST as not enough power to the PSU.

Thats my thoughts on it, knowing me I am wrong, but it's worth a try.

I would advise caution to everyone here. The last thing we want to do is advise something where a lack of experience ends up with something properly broken, or even worse.... on fire.

Have you booted up the PC at all, even attempted without the GPU in place? Can you take the M2 drive out (if it's in) and try again? You want to have the system as it was received from PCS. Switching it on without a GPU will lead to everything coming on and probably an error beep code.

This is personally where I would start.

Once you have gotten this, connect the GPU using 2 separate 8 pin cables. Ensure both end look exactly the same and that the pin connector shapes match. There is a CPU 8-pin along with a PCIe 8 pin, so try not to mix these up.

With that plugged in, it should all work. As suggested previously you should be really careful even considering running a 3080 with a 650w GPU. This would not have been recommended or advised on here.

Thanks for the advice I will try removing the m.2. Firstly though, I am still struggling connecting the PCIE 8 pin to the adapter. It says PCIE 4 on the plug and it is 8 pin. Shapes seem to match up too, but won't go in.

 

[Scott]

I would never force anything. Try switching sides as well as trying to connect them in a different order. It may be an unshapely pin, or it could just be the angle not being ideal to work with.

 

[ProEnigma]

I would do as Scott says first, take out the GPU, and the M.2 and then see if it gives a beep code, I do believe scott is right, the PSU isn't enough for the system that it's being used on.

Edit: ahh I see Scott is helpping you, didnt see the new posts.

I've connected the other cable but still the same issue. I'm currently trying to remove the GPU, but unsure of which way the latch should be on this motherboard and can't find anything in the manual. I don't want to pull harder as I fear I'll cause damage. Also, for the record, I have a TX750M PSU on the way.

 

[ProEnigma]

the latch should be on the right hand side of the slot as you look at it, if it's the TUF GAMING B550-PLUS as in your other posts it should be like this in the image below

I know where the latch is, but I don't know which way it needs to be, in order to remove GPU safely.

sorry, my bad do you mean if you should push or pull the latch to remove the GPU? If thats what you mean, you should push the latch towards the motherboard and then pull gently on the GPU to remove it.

 

[ChaLow]

Yes that's what I mean. The latch was working like a light switch, but now it's not moving at all. It's stuck in the right side up / left side down position. I'm not sure whether that's the correct state. However, it does seem to have locked up, which is annoying.

If I understand you, I believe this video at this time stam will help you 3:41

 

[ChaLow]

Thank you. It seems mine is in the wrong position and refuses to budge unfortunately.

I've taken the SSD out, still the same issue. I noticed the bottom of the heatsink was touching the mobo because I didn't use the riser screw. I fear I might have fried it. How can I diagnose this?

 

[ChaLow]

OK, so finally something. I've removed the GPU (which was more difficult than expected) and it now turns on, with the CPU fans spinning (hurray!). I assume this means the motherboard isn't fried? Anyway, without the SSD and GPU, the motherboard is giving 5 beeps, spaced out differently. It's like 1... 2 3 4... ... 5. I'm not sure if that 5th beep counts as it comes a while later. What does this mean? Regardless, I think it's safe to say the GPU definitely needs more juice.

Im glad you got it to turn on again, I would really look at getting a better PSU, I maybe wrong but it seems like a power problem, seems like it cant get enough, I remember watching a lunis TT video and it showed that in use the new GPUs can spike in power and cause a system crash if there isn't enough over head for the GPU.

The crash is not the same as the caps problem, he was doing 3090s SLI on I believe 1000w PSU and found that while it should handle the cards power, if the GPU spiked in power it would ask for too much and the over volt? or something would trip and cut off the PSU

 

[ProEnigma]

I thought it would at least show a POST screen, but I am at the limit of what I can offer as help, as I just dont that much, I really hope you can get it sorted.

I imagine it should definitely boot. I can't think of why it would do a draw check on the PSU prior to booting. Theoretically the GPU should work on a 650W PSU, it's just when auto-overclocking it would potentially run into issues depending on the rest of the system.

So, with the system now confirmed working, I would attempt one thing at a time. Firstly, the M2 drive is VERY easy to add with the GPU out of the way. I would connect the correct hardware (the riser) in order to properly affix the M2 drive. Boot the system and make sure you get to the same response from the system.

After that, it's time to put the PSU in. As above, I'm not convinced you have sussed out the cables or their connections correctly. You need to be 100% certain that you are fitting the correct cables to the correct connections. If you don't, you can kill the GPU, PSU, Motherboard and basically anything in between. I'm really uneasy offering this sort of advice as it's the sort of thing that beginners should only attempt with someone experienced guiding them.... in person.

I will give this a try. Just so you know, I'm pretty clued up on the technical stuff, just never build a PC in particular. Why are you not convinced about the cables? It was setup by PCSpecialist. All I have to do is plug two (seperate) 8 pin PCIE cables into the GPU right? Apart from that, it's just the M.2, which seems simple enough?

Also, how do I get a response from the system without a GPU?

Edit: So I've put the M.2 SSD back in, with the standoff screw. It felt right putting it in. Now, when turning on the machine, I'm getting a red light on the mobo?

Edit 2: After this, I put the GPU back in and we're back to square one with no signs of life.

Edit 3: I removed the GPU again (trust me, I'm being careful not to force anything) and now when I turn on, the beeps are 1... 2 3. This is getting confusing.

Edit 4: Back to 1... 2 3. I've double-checked the PCIE cables for the GPU are correctly seated on the PSU. I'm going to leave it here, because I'm stumped. The moment I insert the GPU, the issue arises.

It's all relative I guess. It is a simple task but it's also simple to mix things up. There has been a lot of uncertainty from a lot of your postings and this doesn't lead to any confidence. The cables I refer to are the cables that you are attempting to plug the GPU in with. Not correctly installing the M2 drive initially shows a high level of inexperience while charging on regardless.

Without the GPU you should get the BIOS beeps to let you know that the system isn't posting and an indication of the reason why.

You're in a very difficult position as you cannot take the system to another vendor to have it checked out. You could call PCS and ask if they will have a look at the system with the GPU in it to see what the issue is but I fear that may not be part of their support. You can only ask though, there may be a small fee but I think it would be worthwhile.

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.

So unless PCSpecialist are willing to take a look, am I out of options?
