Power hungry 3080ti

Definitely need more than 1x 8pin

Yeah that's for certain. 350W out of a single PCIe cable is dodgy AF.

Thank you for all the replies and help. My full setup is as follows...

ASUS ROG Strix Z490-H Gaming
i7 10700k
MSI Ventus 3080ti
4 x 4266hz DDR4 Corsair RGB
1 x 1TB SATA SSD
1 x 500GB Samsung 980 NVME
1 x 1TB Samsung 980 NVMW
Corsair H150i
4 x 120MM RGB Fans

So no massive power drawing devices....

MSI Afterburner reads (throughout playing COD on normal settings):
GPU Power Max: 331W
CPU Power Max: 101W

I will reseat everything (probably should have done this first).

I have bought a Corsair HX850 so I'll test with that aswell.

If the problem is solved with the HX850. Should I RMA The PSU? It states on its specs it handles a 3080ti

I'm not sure what I'm looking for here on HWiNFO

@AlexCT My mistake, I should've mentioned you need to open up the sensors and not the system summary. VCCIO and VCCSA should be visible if you scroll down towards the motherboard sensor.

Rip to your CPU.

What should the VCCIO and VCCSA be? And how do I change this?

EDIT: For what its worth, CPU never goes much above 50degrees C

Hehehehe

No expert been getting some descent clocking results with the help of @affxct

Manually set you VCCIO and VCCSA voltages to 1.10v and if you have system crashes/blue screen slowly increase then till system is stable,
1.4v is way to high and will damage your CPU over time

I see it. I’m actually surprised. 1.3 IO and 1.4 SA is actually fine. I like to stay below 1.35 for SA, but this is actually not in the danger zone. I reckon you should be able to get away with 1.3 IO and 1.3 SA for 4X8 4266, but only because tRCD and tRP are both 26.

To change them both/lock them both to 1.3, you’d just need to head to BIOS after a reboot/cold boot, and scroll right to the bottom of the AI Tweaker menu. They should be labelled ‘IO Voltage’ and ‘System Agent Voltage.’
