Newer Graphics Card does not work, older one does

So hey.

Let me explain everything:

I recently bought some new parts for a new computer. After i built it, I tried to start, aaaand nothing, not even a "piep" from the mobo speaker, only all lights and fans work.

The Graphics Card I have is a Asus Strix 1060.

But here comes the, for me weird part:

My MOBO has 1 PCI-Ex16 and 1 PCI-Ex4 slot. In the x4 everything works, in the x16 not.

I know its not the motherboard because of 2 reasons:

1. I tried 3 different motherboards
2. I tried an OLDER Graphics Card and it works just FINE

Thats the weird part, my old Graphics Card (GTX 750) works just fine in both PCI slots.

Rest of my System:

CPU: AMD Ryzen 5 1600x
RAM: Corsair 2x8GB (3000MhZ)
Motherboard: Gigabyte AB350-Gaming
Powersupply: Dont know the exact name, but it has 700 WATT

So, can anyone please help? I'm already trieng to fix it for 2 weeks with no success..

One weird thing comes also now, SOMETIME (like 1 in a billion) the PC does boot like normal in the x16 slot with the 1060. If that happenes, everything works just fine till I shutdown and try to start again, then again, nothing..

So if you have any ideas, please help..

Things I already tried:

- Bios update/reset
- Changing PCI to Gen3/2/1
- Tried 3 different boards


Also the 1060 works fine on my old system with my AMD-FX8350 IN pci-ex16.
 
The GTX 750 works in both PCIE slot in new board. The GTX 1060 works in old system. Maybe the PCIE X16 on new board can't manage the power draw by 1060 and the PSU might be problematic too. Maybe not a real and reliable 700W unit; which is way more than enough for that system to begin with.

If memory serves right I think the GTX 750 needs 55W. The GTX 1060 draws more from the slot and needs a 6-pin PCIE auxiliary power connection from the PSU; a total of about 120W give or take.

What is the PSU in the old AMD system?

You tried 3 different boards means you replaced the same board twice or different brand/model boards? Anyway did you try all these boards with the same 700W PSU?
 


The PSU is the same (from the old AMD system)

The MOBO: First one was from Asus, Then I got the one I have now and replaced it with a new one.

I dont think that the GPU is drawing to much power, why should It work in the other System flawless then?
Also the one time the System DID boot, I installed a Benchmark tool and ran it. The System worked flawless in the Benchmark, so there should be enough power.

The 750 has no extra power connector, it takes all from PCI, thats right.
The 1060 has 8 Pins (I tried to boot with only 6 pluged in, what would be enough for normal, and with 8)
 



I thought maybe you have a new PSU and the AMD system has another one.

How many 8 or 6+2 PCIE power connectors does the PSU have? Have you tried changing the connector and cable if possible?

You didn't say what brand model the PSU is. PSUs and age not the best combination.

Yes it might have booted once and yes it might work in the AMD system but I think it's probably the PSU not being stable and consistent enough.

You have changed motherboards and the 1060 boots on the AMD system too so the card must be OK and it did well in a benchmark. I'm guessing the PSU is the culprit.
 


I found the PSU on amazon: https://www.amazon.de/gp/product/B00S18A90O/ref=ox_sc_act_title_1?smid=A1KKI2FLN5FUNB&psc=1

I know it is not the best PSU, but it did serve well till now (I would be VERY VERY happy if it would only be the PSU, but i have to be sure it is, so I can buy a new one, I cant afford a new Graphics Card :/)

It has 2 6 Pin and 2 2 Pin. I tried changing them in all ways, nothing.
 
Only way to make sure is to test the PSU but I would change that PSU as soon as possible.

Especially since it's a few years old. It's not 80 plus certified and I can't really find any reliable reviews.

It has a floppy drive power connector and 3 12V rails. The design must be really old.
 


How should I test it anymore? I already did what I could.

3 Other questions:

Can you recommend me any powersupply?

How sure are you that the PSU is the problem maker?

COULD it be any other component? CPU or so?

I just want to be sure.
 


Also if you want to see exactly what happens, here: https://youtu.be/NCFsWlPj1ec
 



I mean testing by someone with the proper know-how using testing equipment or a multimeter.

The other card works in both slots on new board that kind of rules out a broken motherboard. Your new card works on old motherboard and that kind of rules out the new GPU being faulty. That makes a not-so-great old PSU the main candidate.

You never know unless you go through thorough elimination processes for other components.You changed motherboard and used 3 boards. Other old card works in current new board. New card works on old board. That means most probably they're both OK.

CPU are very very rarely faulty and they don't die that easily. If anything is wrong with the CPU the system should not POST with the old graphic card.
 


Well, sounds pretty logic. I already ordered a new PSU on amazon, should be here on 21th. Will test it then.
Could the RAM also be a Problem maker? I mean, I see no reason why, the new card does work in the x4 Slot with the RAM, but who knows.
CPU.. yeah probably right, should not even boot with any card if its faulty.

I wanna thank you for your help, but can you stay tuned here? I will post my result with the new PSU as I get it and you seem to know much and already helped alot.
 



No problem, glad to help. Yes I long in from time to time and will check threads I'm following. I don't think it's RAM but it never hurts to test RAM sticks with a bootable Memtest one stick at a time.

I hope you ordered a good model PSU from a reliable brand. More or less every components health, performance and longevity depends on the clean electricity from the PSU.

You can also ask around for other people's opinion and experience.
 


Well, got the new PSU now, aaaand... nothing. Everything is still the same :/.
I mean, now? It can only be the Graphics Card, or not? I mean, I know its weird that it works in the other system and slot and SOMETIMES also in the x16, but yeah.. what else should it be now?

A thing that may confirm the GPU to be faulty (i did not mention that before sorry), sometimes the new GPU does not boot correclty in the x4 slot either. The PC does boot, also into windows, but the GPU gives not Video signal. So maybe its the GPU for sure?
 


Well, changing that PSU was a good move regardless. And you ever told me what PSU you got.

If it does not POST/boot with the new one in X4 slot either that might indicate a problem with GPU. Has this ever happened with old GPU on new board? If it never happened the motherboard/and slots should be OK.

Having changed the board 3 times made the PSU (more likely) and GPU candidates. Can you try the GPU on another system? A friend's perhaps?

How do you know that the system boots and Windows loads normally if no video signal? Windows sounds? Asking because that CPU has no integrated graphics.
 


Yes that did happen with the old PSU too (that the system wont boot on x4). But that happened rarely.
It never happened with the old GPU yet.

No of my friends has a modern system :/ So no I cant test that on somebody elses system :/

Yes the CPU has no integrated graphics. But I know because Windows loaded the Drivers (GPU fans stop spinning when drivers are loading)
