Pc shutting down when on high load

[JonyDimit]

Hi everybody!

 

I have problem with my PC, and I can’t determine why that is happening.

Sometime, not every time, when I’m playing RS6 siege and Quake Champions (everything maxed out), my PC turns off and then turns on itself.

I tried troubleshooting it, but I still don’t know why that’s happening.

I think that maybe power supply is too weak, or motherboard is potato.

 

This is my specification:
CPU: i9 10900F
GPU: Nvidia RTX 3090
RAM: KINGSTON HyperX FURY RGB 16GB DDR4 3200MHz CL16
Motherboard: Asus PRIME B460M-K
PSU: ROG-STRIX-750G 750W

Case: Fractal Torrent with ARGB fans
AIO: Corsair iCUE H170i ELITE LCD Display (I’m using push pull, so I have in total 7x140mm vents and 2x180mm)

 

Regarding the processor, I changed some settings in BIOS so now it can draw 220w of power instead of 65W.

Prior RTX 3090 I had RTX 3070 with same processor and settings I didn’t have any problems with PC shutting down.

For RAM, XMP is enabled.

 

I tried running FurMark on couple of maximum resolutions, and I was running it for 1hr, with temps of 68C and nothing happen.

I tried running CPU stress test (HeavyLoad app) and I was running it for 1hr with CPU temps around 58C, and nothing happened.

But as soon as I run one test (for example CPU), same millisecond I click to run graphic test (and reverse) PC turns off.

I placed video in attachment of that.

 

Thank you for help in advance!

The combined load of your CPU and GPU could couse your your OCP (over current protection) to trip up.

The 3090 draws around 125~150 extra watts compared to your old 3070.

People have run 3090's on the 750 even 650watt PSU's, but this unit is made by seasonic, and their lower wattage PSU's combined with their OCP,OVP can trip up high end systems and force a shutdown.

 

Your thermals are not at fault here, your PSU can probably not handle the combined load without trying to protect itsekf

*note that this is just from what I can find right now, I'd love someone elses opinion

If it can't handle CPU+GPU load at the same time, that points to a PSU (power) issue.

 

The CPU can draw up to 224W.

The GPU has a power draw about 350W to a peak of 365 nad transient spikes at least double.

 

Your PSU can handle 744W on 12V and your CPU+GPU reach almost 600 out of that.

Now, you have a lot of 12V fans with lighting, and the machine does consume a lot...

 

I would test with a stronger PSU. Or, at least, revert the change you've made to the power draw (removing the TDP limit) and test that way.

Thank you guys for reply!

 

I would like to change my current PSU.

Which 1000W Seasonic PSU you recommend?

Seasonic

Why does it have to be Seasonic? There's other vendors too.

Yup.

[JonyDimit]

Does not have to be Seasonic, I just want to purchase good one so I don't have problems with system shutting down

Yup.

Doesn't have to be, SeaSonic is just one of the most "premium" vendors, asus, Corsair etc also works, as long as it's a well known brand.

What would you be willing to spend?

[JonyDimit]

Damn, looking at all of those PSU-s, and I'm confuzed. Which one i should take? 

For example I was looking at Pure Power 11 FM and I saw this for that one: Be aware that strictly multi-rail units (without a possibility to switch to single-rail mode) can trip with very high power draw GPUs (RTX3080/RX6800XT and higher) and/or CPUs (unlocked Intel i7/i9 or AMD Threadripper) due to lower OCP tripping point when the load on rails is unbalanced. Read the manual and balance out the load if that happens.

 

Which is the same problem I have with ASUS PSU.

 

So If anybody can help me to decide which one to take, I would appreciate that

 

My budget for PSU is around 300$

Basically any a tier unit and the cheapest one so you save money

I always recommend Corsair RMx series - if available to you, you can have a look at these as well as a replacement 

[JonyDimit]

After long search, I couldn't find in my place Corsair RMx series (out of stock) but they recommend me as replacement this one:
ASUS ROG Strix 1000G 1000W 180USD

 

Should I take it, or no?

[JonyDimit]

And in the end I ended up purchasing "BE QUIET! Straight Power 11 Platinum 1200W"

Hopefully it was good choise

That is a really good PSU. A bit much sure but this will last you through multiple platform upgrades

Absolute unit of a PSU. You’ll be fine, very solid choice

[JonyDimit]

Thank you all for help! Problem is solved with new PSU unit
