[nikexa1351]

Hello everyone. So recently i bought the GTX 1080 ti but it wont boot. When i turn on the pc with the 1080 ti im just stuck at black screen and cant do anything. Ive got GTX 1060 that works just fine in that pc.
What i have done:
Tried diffrent GPU in my pc and it worked.
Tried the 1080 ti in another pc and worked fine.
Changed my psu to 650w bronze 80+

My pc specs:
CPU: AMD Ryzen 5 2600
MBO: msi a320m pro-vd/s
RAM: G.Skill 16GB DDR4 2400 MHz
HDD: 1TB
SSD:Kingston UV400 140GB (OS) and Adata 480GB SSD
OS: Windows 10 Pro

Exact make and models of previous and current PSUs ?

 

[nikexa1351]

LC55550 V.2.2 550W. (It has only 1 pcie (6+2) but i used the adapter for other pcie i needed. Didnt work but when i plugged in the 1060 into adapter worked fine)
Azza 650w ARGB PSU (I bought this one as it was the psu i used in the pc that i tested 1080 ti in and it worked there, It is 650w with 2 pcie (6+2)

Adapters are an awful idea. If the PSU you use does not have the connections needed to power a GPU then it's not meant to power it and should NOT be used for that GPU.
A 1080ti uses FAR more power than a 1060 so it's not surprising that the 1060 was working (with high risk though).

Your first PSU is NOT a 550w unit. It can output 400w MAX on the 12V rails which is what powers every significant hardware and how modern PSUs are named for wattage. That alone makes it a crappy PSU.

Your second PSU is also crap. 576w max output on the 12v rail. None of these PSUs are good enough to power properly a 1080ti.

Now as for the card was working with the second PSU. I don't doubt it did but you might ended up damaging it with the first one and the second just pushed it to the limit of total failure. That's just a guess.

Can you tell me the exact order you did things and if you tried benchmarking or playing games?
For example: first installed in PC A with these specs... Not working. Then to PC B with these specs.... Working and stress tested for half an hour with heaven benchmark.

My main pc just doesnt boot with that gpu at all, its 1080 ti strix model that and 2 led lights light white when i plug the pcie cables in but nothing after that. I tried updating bios, uninstalling old drivers etc but nothing worked
