Hi, Sifus. Please help me on this.





Update 2:
Received another RTX 3080 of different model from someone else. Had been using for two days, seems to be all good. Thanks for those who actually helped me diagnose the issues. Closing this topic.

Also giving credit where credit is due, thanks to Babylon for giving helpful information. Read everything and picked up a lot. I hope in the future he can at least teach better without mocking or jabbing though, since not everyone is as knowledgeable. So I'll leave the info he has left here.

Make sure the power cable to the 3080 is the correct one.

Try reseat the RAM or if it is more than one stick than try a single RAM at a time at different slot.

Or try the 3080 on another system.

1. no fan even CPU Fan?

2. Plug in back old GPU everything Works?

3. which slot you installed your GPU??

4. do power flush with new GPU

5. a PIC of all angle, how you install the NEW GPU.

Make sure you use one cable per 8-pin pcie. Do not use single cable for two 8-pin pcie.

1. Its definitely the correct cable(s), PCIe.
2. My RAM is 4x8GB (I realised I have forgotten to list the configuration), and I also tested one by one.
3. No other system available at the moment, sadly.

1. No, not even one fan. Its only with this RTX 3080 that it wouldnt start. Without it, or with the old GTX 980, everything is fine.

2. Yes.

3. There are 2 slots on the motherboard. I tried both, no luck.

4. Tried, no luck.

5. Not sure which angles are useful to you. Let me know if you need more / clearer angles.

And I tried separate cables (1 per 8 pin) and same cable (1 for both 8s), still no luck.

very weird.

even Faulty GPU can boot.

from your description. the entire PC refuse to TURN ON.


" you have a short in your pc "

i hope is not your GPU caused the short.

but seeing from the picture, is very tight.

I hope not too. Today I'll have more time to test it out, and with another system. The journey continues... Thanks for helping.

How come your power cable to mobo EATX connector is routed UNDER the GPU? It should be routed BELOW the mobo.

when u say u uninstall your driver, did u use DDU to do so?

Cant power on, not even POST...

no Disk drive also can boot. how can this be driver problem?

Yes I did. And I just tried on a different system. It sparked and smoked... I guess its DOA. Going to ask seller for an exchange. Thanks for helping.

Not sure what you mean by this but if you are referring to the left braided cable, it is not a power cable.

Adoi, 3080 required min 700W PSU and in practical needs about 850-1000W due to 30series transient spike. Somemore CV550W unit is D tier, totally not Not NOT! suited for a high powered GPU in 3070-3080 segment. Ur lucky that puny 550W unit did not fry, or perhaps it did and took down ur GPU as well.

Even that RM750e is barely boleh pakai, your taking a chance there if still getting another 3080. Up it to a 850W A tier at least.

PS when you go high end your gotta make sure the other components can support it too

Thanks for the advice but I have to disagree with this. It's not a no-brand power supply, could you explain why it will "take down" my GPU? Surely, at most if not enough power it will just shut down the entire thing. But I agree it is inadequate, so I decided to change it. I followed Nvidia recommended minimum power at 750W, and RMx is an A-tier PSU.

u are right, totally nonsense.


no psu design to break when 100%
and GPU not always run on full power mode.

even NVIDIA official didnt say u need 850w for 3080

his opinion is inaccurate

if sparked

something melted and caused shorted like i mentioned.


i guess, this is a mining card?

Trusting a brandname to be consistent is a real fallacy which most companies hope their customer to blindly rely on. This is why the PSU Tier List exist.

While Corsair higher end PSU are good quality stuff their basic & cheaper options are really just budget stuff with Corsair name tacked on. Your CV550 is a D tier rated unit only suited for igpu builds and you shoved a 3080 into it. LOL

Transient on 30series is a well documented issue and GN had done an indepth review on it


You can disgree but GN is a well trusted PC hardware reviewer and they present facts to back that up

A 3080 has transient that draws nearly the whole capacity of your 550W unit (which actually has a real capacity of 528W), what about the others like CPU, Mobo, RAM, fans & storage?


And this is what GN deduced from their investigation; the trip happen on the 12V which triggered OCP


Now see, good PSUs has good & complete protection. Cheap & budget PSUs typically lack full coverage and even if it stated to have OCP it may not be fully effective and overcurrent in the 12V rails could have passed on. Guess what, your GPU 8pin supply is directly connected to the PSU 12V rails.

This is the wattage unit GN reco to use. So its needed nearly 50% more than your 550W unit could handle!


Yes, you gotten a 750W A tier PSU but thats only AFTER shit happen isnt it? Its likely your GPU is ady killed before you upgrade to the 750W. And this is the bare minimum that GN recos you havent factored in if you will upgrade anything in the future or that PSU ages and thus its ability to handle "real" 750W will deteriorate with time. Mate, if you can afford a 750W A tier PSU, an 850W A tier unit isnt that much more costly.

Its between your words and GN. And far more in the internet community trust GN.

I agree with this. But some people really still don't believe because it works for them. They proof that, hey I use some lower powered GPU and no issue it works. Well, it works until it didn't. Then they will be wondering why it died. It's hard to convince them but glad u made an effort.
