3090 and 3080ti Systems Crash.... 3060ti Works?

[MBeal08]

Spoiler

 

So I have three systems (below from PC part picker) two of which aren't working. 

 

Both the 3090 and 3080ti system are experiencing power loss. After about 30ish minutes, the systems hard reset no matter what I am doing (editing, playing a game, or just browsing the internet). After that initial reset, the time the systems can remain on diminishes in what I can only describe as an exponential decay. The next time I can only get 15 mins. Time after that 10, 5, 2, and then finally the systems will power cycle immediately when plugged in. I don't even have to hit the power button and they will quickly cycle but will not boot. If I leave the systems completely unplugged for a day or so I get back to that initial 30 mins. of run time and start the process all over again. 

 

I took the 3090 system to a local microcenter for diagnostics, they could only find that a power loss was occurring at my home, but could not replicate in store. I recently moved to an older high rise in NYC (and this is where I am a bit fuzzy on exactly what I was told...) and the tech mentioned it could be a problem with the power coming in from the wall. I didn't have an issue before moving so I think he's on to something. 

 

I went out and grabbed this power conditioner and this UPS as someone suggested it may be worth trying. Zero luck. I've also tried every outlet in the apartment and every power cable I can find, zero luck. 

 

Anyone have any clue what is going on? New PSU(s)?

 

I am willing to try even witchcraft at this point if it means getting my systems back up and running.

Maybe try the 1200w power supply with the 3080ti. Worth a shot if you haven't already.

Kinda a shot in the dark.

[MBeal08]

I would... but it won't fit in the case I have the 3080ti in, sorry forgot to include the case. I also just noticed that I have the 850W Thor PSU (same PSU as above just 850W) in the 3090 build currently. I ordered the 1200W in a fit of frustration last night and looks like it auto added to the list.... hopefully that does it? But, based on current results I'm not too hopeful.

Have you tested the pull from the wall on the systems?  Get a Killowatt unit and see if they are able to actually get the power needed.

 

Nothing else screams issue, but the PSU's may be unable to get what they need.

 

New York can experience electricity dips (especially in older buildings), most people won't notice them until they hit a brownout stage, but if you're running high draw machines out of one unit...

 

When was your building built, what code standard?

I haven't tested the pull yet, I'll give that a look next.

 

The building was built in the 1970s I believe, not sure on code standard. 

 

Let's say that is the issue... then what? Redoing the electrical isn't exactly an option haha

We can get an idea of how to distribute the load possibly.  Are the PC's in the same room, on the same breaker/fuse?  Is it an issue with the unit as a whole?

 

We can possible put limits in place on the GPU's to lower their draw.

 

UPS may help if it's just spike thing.

Gotcha, the unit is a one bedroom so not many outlets to try, but yes same issue no matter location. I’ve also tried them individually and without just about anything else on in the unit, no luck. 
 

The UPS didn’t seem to help either (I may have gotten a little more run time than before), but the end result was the same.

I have several similar systems. 

 

The issues I have had is with faulty cables that came with the PSUs. 

 

One was the cord to the wall. I found the fault by wiggling all the cables.

 

The other was a faulty 24 pin motherboard cable. This computer worked with a GTX 1080 but not with a RTX 2080 ti or 3090. Wiggling the cables in the computer found it. 

 

Recommendations:

 

Both flaws I had with cables only appeared after the systems heated up. So I would heat it up then wiggle the cables. 

 

Test the 3080 ti and 3090 computers with the 3060 ti.  To test for an internal power delivery issue.

 

Make sure you are using 3 separate PCIe cables to the GPUs.  A must for the Strix cards since they can use over 450 watts.

Interesting, didn’t even think about cables that came with the PSUs. I’ll give that a go too.
 

Did your problem occur immediately? I was good for about 6 mos. until we moved. I know that everting is in place post move (nothing came loose) since Microcenter’s diagnostics showed everything was good.

Both problems accrued months after instillation. That is one of the reasons they were hard to spot.

 

Going to Microcenter is like going to the car dealer. If they can't duplicate it, they can't fix it.

True to an extent.  If it's not an issue at Microcenter, they're either using their own cables or there IS not issue at Microcenter (if it's your power).

 

Due to the relationship of moving and problem, I would say the higher likelihood is the building's power.

The work load may have not been enough. The time they tested may not have been long enough. Lots of variables.

I have done that type of work in the past.

With a UPS it would start beeping if there was not enough power from the wall and they scream if you try to pull more power than they have. So they are a good indicator of power quality.

Mine beep a lot this time of year since there are thunder storms every day. 

 

The only power issues that I have come across before where live grounds and most lights and appliances are fine with it but computers are are not. 

 

[MBeal08]

Thanks for the help everyone. Looks like I’ve got some homework to do. I’ll swap out the cords going front the GPU to the PSU and pick up a meter to see how many kWh I am pulling from the wall in hopes of determining if I’m getting enough to the PSU to power the system. 
 

I will report back! Thanks! 

[MBeal08]

Thanks everyone, I think my problems are finally solved! I switched out the PCIe cables and poof! all problems gone. I really appreciate everyone's input... it looks like the cable issues just happen to start occurring at the exact same time as I moved, what a weird coincidence.
