Hey everyone!
I recently upgraded my PC build recently to feature 4 x 3090 RTXs. I've got a custom loop for the heat + 2000w PSU and was doing some rendering out some scenes to see how they went and a few times the PC just suddenly shut down right after the render finished. Worst thing is, it didn't even save the image file to the PC so I didn't get anything out of it.
Is this something to do with my PSU not having enough power?
I'm running the latest version of Octane on Cinema 4D on Windows 10. My GPU cards are all up to date and I was monitoring the VRAM and GPU heat levels via GPU-Z and everything was working fine.
My PC specs are:
AMD Ryzen Threadripper 3960X
TRX40 AORUS XTREME
128GB Ram
4 x 3090 RTX
Custom loop
FSP CANNON PRO 2000W 80+ GOLD
I just ran GPU-Z and noticed the PerfCap Reason says Max Pwr - so that means the PSU is over powered?
Potential solution 01: I've been told to look into MSi Afterburner software and limit the power to 300 per card but I also want to get the max performance seeing as I used a tone of my savings for this build, it would be a shame to not to. But wanted to get some advice here first
Potential solution 02: Get a 2nd PSU
Potential solution 03: Undervolt the GPUs
(please have in mind that PC hardware is still relatively foreign to me, I know basics but not enough to start tweaking it myself, hence why I've come here for help).
Cheers!
Any help would be appreciated!
