RTX 3070 - Causing constant resets

[Barbarian Conan]

So, I have recently acquired a Palit GeForce RTX 3070 GamingPro OC.

Long story short, it's causing games to reset the machine, suspect PSU, lowering power limit to 60% seems to mostly 'fix' the issue.

Just looking for any advice / ways to focus in on where the issue is, before spending yet more money on a PSU. Specs as follows:

• ASRock Z97 Extreme6
• Intel Core i7-4790K
• DDR3-1866 (16GB)
• Samsung SSD 850 EVO 1TB
• Windows 10, etc

I've done all the obvious things I can think of.

As I say, likely need a new power supply, but maybe I am missing something.

All that said, when it worked, for brief periods, quite an upgrade from my 1070.

As you know and others have said, the part in bold pretty much makes it a sure thing that your PSU is to blame.
I had the same issue with my 3 year old ThermalTake Toughpower 650W and my Radeon R9 290 back in the day, underclocking/changing power limit "fixed it" until I could get a new PSU which really fixed it.
Your 3070 OC model probably consumes close to what the R9 290 did.

Are you using a splitter to split one PSU output into 2x 8-pin?

Could definitely be the issue, I know nVidia recommends separate cables for the 3080 at least. Saw somebody on reddit with a blown PSU because he used the daisy-chained connectors on a 850w PSU with his 3080.

If the 650W PSU is up to spec, are you using one or two PCIe 8 pin power cables? Don't try use one cable with two 8 pin plugs.




Use two individual 8 pin cables (so two from PSU)

I've got a 3060Ti running on a 450W SFX power supply, which uses only slightly less power and I haven't had any issues. I only actually realised this now thinking about it, probably wouldn't recommend doing this but it's what was in my mini ITX system and didn't give it a second thought.

If the 650W PSU is up to spec, are you using one or two PCIe molex power cables? Don't try use one cable with two molex plugs.

Discovered this when overclocking my 1080ti.

At the same overclock where I had stability issues on 1x cable "split" (ie one cable with 2x 8pins) changing to separate cables instantly netted me stability at the same overclock.

I upgraded to a 6800XT and gave my son my Vega 64. He kept losing signal to the monitor, which turned out to be not enough voltage from one cable to the card via one cable. His RX 580 had no issue running one cable, but the Vega 64 is much more power hungry.

3070 on a 550w PSU here. I'll upgrade soon it's been fine so far. But I have a Ryzen 3600 sipping 65-80w.

My 1080ti (manual overclock) uses >300W when fully utilized. My i5 8600k is running @ 4.8ghz. I have 2x HDD's, 2x SSD's, 1x NVME, 16GB of DDR4 @ 3600mhz and no shortage of RGB goodness.

All of this runs just fine on a 620W (Gold rated) PSU

I would expect I'd continue to be fine swapping out for a 3070.

Doh - Thought I had included the PSU, which is a Corsair VS650, and it's about 3 years old.

Yeah I dont trust that PSU at all.
I had one from a previous build that I tested in my main rig about a month ago, exact same issues you describe, would be 100% for normal browsing etc but anywhere between 2 - 5 mins in game and the pc would reboot.
Changed my PSU back to the 750W I had previously thought was faulty and the problems all went away.

Its been hot lately and I dont think the VS650 has very good cooling so I think it was overheating. It wasnt a power draw issue as my card will run fine on a 550W.

Running an i7 10700k oc and RTX3080 on 750w power supply with zero issues.

 

[Elon]

I think it was a YouTuber named Igor who discovered that the RTX 3000 series will occasionally have brief power draw spikes of around 30%. The issue seems to have been fixed with subsequent driver updates. Then there was the issue with board vendors cheaping out on the power delivery circuitry to hit the MSRP but that was only for the 3080 AFAIK.

Corsair VS PSU's are garbage. Its an el cheapo with a Corsair sticker on the side to make it look pretty and make you think you have bought quality.

I have a Corsair TX Gold Cert 650w PSU and it handles a 2070 super plus many hdds / water cooling just fine.

 

[ArmatageShanks]

I had the same issue, PSU not sufficient for the GPU.

I discovered it by taking a multi meter any physically probing the 12v inputs at the GPU, discovered under 100% load it would drop to 11.3v then crash, so I reduced the power limit with MSI Afterburner to where the voltage wouldn't drop below 11.7v, which is about 60%.

Working fine until I get another PSU.

I've tried all combinations, no dice. That said, I just got a new PSU to test, and will do so this evening.

Its 80+ White certified, damn son.

Get this.

Racist!

Well they are the worst...kind.

Geez, PSU's have gone up a tad since I last bought!

Damn cheap considering everything.
