There are three PCI-E connectors running to the GPU, and one PCI-E connector running to the corner of the motherboard. I picked one of the 8 pins to measure resistance with an ohmmeter. Resistance is near 0 ohms between the same pin on each pair of PCI-E pins running to the GPU (all 3 GPU PCI-E connectors are in parallel, on the same rail).  I measured resistance between that pin on a GPU PCI-E cable, and the same pin on the motherboard PCI-E cable. Also near 0 ohms. So everything is in parallel (GPU and motherboard), on the same PSU rail. The PSU itself has no visible name brand on it, or other specs on the box. It's screwed into the case, and I have not tried to remove the PSU, which is obviously connected by a number of cables to the various components. Everything is neatly cable tied together, so removing all of these cables and PSU will require a bunch of cable tie cutting.
 
I will rattle CyberpowerPC's cage next week when I have time, and during business  hours. For now, they haven't responded to my detailed emails to techsupport at cyberpowerpc. I will determine over the next few weeks whether this really is cyber junk or not. I cannot easily tell what kind of PSU they put into this PC. And it's not 100% clear to me whether having all of these PCI-E cables in parallel (same rail, GPU cables, and motherboard cable) is a reliable arrangement. I'm also not encouraged by the fact that they substituted a different motherboard than what I ordered, though it's using the same X570 chipset. According to this, the motherboard I received is not inferior to what I ordered:  copy & paste URL versus.com/en/asus-prime-x570-p-vs-gigabyte-x570-ud

Thank you for posting this.  But can you tell which motherboard you have?
Please check the top of the motherboard by the CPU to your left, you facing the board,  if the 4 and 8 pin connectors from the PSU are connected to the board. I think the board requires more juice.  If not, clearly the PSU is not good to handle the hardware in your machine. The PSU model number you provided, in amazon cost $74, for a 1000w PSU might be a steal, but like another member stated, it may not be 1000w 100% it might be pushing less than advertised.
Real quality 1000w PSUs does not cost that much, they cost more.  If I am not mistaken, you can reach them on facebook or twitter, if you like.

I guess they substituted ASUS for Gigabyte (same X570 chipset). The BIOS that came with the PC was a version from 08/2020.  I saw crashes under load with both the older BIOS, and the current version 3405. So the latest v3405 didn't make matters worse, but also didn't fix anything.  I've seen a number of web pages devoted to crashes with these cards, e.g. .  I don't know if this kind of hardware issue is what is causing the problems with my system. The driver I'm running is the latest from NVidia (27.21.14.6172 dated 2/23/2021).

Atfrico, he did....He has an Asus Prime X570-P
 
 

I oversee that...lol. Thank you.  He has a solid board, cant say much about the PSU.
Like Sajin stated, try to boot the PC with 1 memory stick at a time to pinpoint if you have a memory stick defected, although i doubt it.  The problem with no having a reputable made PSU, is that you cannot set everything in auto when it comes to voltage, the board might or just simply the GPU will pull more voltage than advertise.

Could be the psu. That model has known problems with rail fluctuations... May not be efficiently enough for the power draw of the 3080. Ive had to send one back because of problems with a 2070... Same model. New one worked fine but was later replaced with a more reliable evga psu.

I posted earlier that measurements with an ohmmeter confirm that the motherboard and GPU PCIe connectors are on the same rail, which agrees with DavidDSwenson's findings on newegg listing.  It's a really cheap 1000 watt PSU - I saw it listed one place (walmart) for close to $90. That may be the culprit. I realized that I've been connecting PC power through a surge suppressor, so I tried a direct power connection to the wall. It still crashes after about 10 minutes Unigine Heaven 4.0 (ultimate quality, tempered glass re-installed so everything heats up faster). It then reboots, and often crashes again right away. I then turn the power off for a while, let it cool, and it seems to repair and reboot successfully.
 
It could be the PSU, bad GPU, bad CPU, bad memory, bad motherboard, or I'm not sure what else. If it's the PSU, why does it crash again after I reboot?  Unigine Heaven is no longer running after the reboot, but temperatures inside the case remain pretty warm. GPU temperature during the test never exceeds around 80 deg C. CPU temperature never exceeds around 70 deg C. The case near the PSU never feels hot. I realize that the problem could be voltage transients, but that's not been proved, and if that is what is happening, I can't tell it's the PSU without trying a different one.
 
I can buy a better quality PSU and try it. But that may well not be the problem. And installing it on a brand new CyberpowerPC will require that I remove and re-install all of the neatly tied power cables. The PC sure looks nice, but it doesn't run reliably.

Ok if you think the hardware is overheating have a fan point at the inside of your PC, but in reality, and i tell you from experience, is the PSU, when hardware or electronics are not getting clean electricity surge to function, they tend to overheat. 
I had the Thermaltake tough power 1200w PSU for 5 years running my present build, and i noticed the rise of temps inside my PC and the CPU, even though i have a 360 rad loop running the CPU, only. I decided to get the best 1200w PSU at the time and it was the EVGA PSU 1200w Platinum. My CPU nnd PC temps dropped after the PSU swap and i learned that PSU is the one thing that can affect not the temps but the performance of all the parts in your PC.

I have a new CyberpowerPC ..

I could not find any good reviews on that PSU. The fact that i's input power draw of 8 amps at 115v is less that its claimed rated MAX never mind continuous output... is not a good sign. I'd opine a garbage PSU is a prime suspect.

P.S. I was seriously considering building the PC myself, but I'm not willing to pay a scalper price for an RTX 3080. CyberpowerPC can obtain those boards without any problem, but with a several weeks delay. By the time I'm done with this, I may end up rebuilding it. Great learning experience, if I don't fry any expensive components along the way.
 

I am in the same shoes as you were, and I will pull the trigger on getting a Cyberpower build too, since the scalpers are not going away. Don't feel bad, you are not the only member with PSU issues.  Donta also has a PSU that needs to be replaced from Cyberpower.

I checked the BIOS settings for memory resize bar, and it's OFF (I never turned it ON), so that is not the culprit.
 
Thanks to donta1979, I registered the card with EVGA. I also submitted a question about this whole thing to the online service center, referring back to this forum thread. I'll update the thread when I find out more, either from CyberpowerPC or EVGA.

If it happens to be the card I would only do an RMA with it though EVGA.

ddi you check if they removed the plastic wrap from the cpu cooler?
tons, for real tons, of ppl on reddit posted screens of that wit ha cyberpower prebuilt.

which plastic wrap? Hope you don’t mean the cold plate because that would be pretty sad lol. 

BTW I recall removing a layer of clear plastic from the liquid cooler plate, along with packing material from inside the case. I can imagine that some people would miss those things, and end up with burning plastic. The Quick Start instructions from CyberpowerPC mention removing the packing material from inside the case, but nothing about the circular clear plastic wrap over the liquid CPU cooling plate.

The scalping situation with these cards is really insane. I guess that gamers are the main victims, but they're not the only ones who would like to try out this kind of SOTA hardware.

I have run the tests with the tempered glass removed. It ran for significantly longer (over 30 min) before crashing, but it still crashed. I also removed the back meta panel alone to measure the PSU voltage. That also appeared to run longer without crashing, but I didn't run that test until it crashed. Less ventilation clearly makes the situation worse, but more ventilation doesn't get rid of the crashes. I also observed that after crash and reboot, I often had to wait a while for everything to cool off before the system would stay up & running.
 
I did log the GPU temperatures up to crash using GPU-Z (also sent that to evga support), with the case closed, and I don't see any excessive GPU temperatures logged. The last line is right before a crash.

Check the bios and set/run the fans at 80%. The fan GPU profile is set up at certain temps when it reaches to a certain temp, it shuts down. Probably the techs at cyberpower set it up for you.
Do you have precision installed?

No precision installed, whatever that is. BIOS fan settings are set at all defaults, except I had to set it to ignore CPU fan. There is no CPU fan - liquid cooling in place of it. The case fans are always running, and this setup at low load is significantly noisier than my vintage 2014 HP PC with Intel i7 and Intel HD graphics. That system is way quieter, way less powerful, and so far way more reliable. I believe the reliability problems with this system are the fault of the GPU card. The other system I have sitting here, a mid 2010 Mac Pro, was also noisy at rest. It has now donated its Radeon RTX 580 graphics card to this system, until I have a reliable RTX 3080 card.

Another possibility - some PSUs have had false triggering of their over current protection (OCP) & shutdown the PC unexpectedly
