Question New Build Restarting during gaming - High settings only

[ozzie86_uk]

Hi all,

Recently decided it was time to update my motherboard, CPU, and RAM after upgrading my GPU last year.
Ordered the components and installed them without issue or so it seemed. I've found that everything runs without issue until I up the graphic settings on certain games.
I obtain a solid and stable 60fps with most titles but if I up the graphics too far I get a reboot of the entire system - no slow down, no error message, no warning, just a reboot.
Everything aside from the PSU is brand new over the past year or so, with the PSU being roughly 4 years old.

• Motherboard: MAG B650 Tomahawk WiFi
• CPU: AMD Ryzen 7600
• Cooler: Dark Rock 4
• GPU: Asus GeForce RTX 3060 TUF OC V2 12GB
• RAM: Corsair Vengeance 32GB 5600MHz AMD Expo DDR5
• SSD: WD Blue SN570 1TB M.2
• PSU: Corsair CX750M (75-002019)
• OS: Windows 11 22H2
• BIOS version: 7D75v11
• GPU Driver: 528.49

Tracking the temperatures doesn't appear to show any spike before the resets and games sometimes stop instantly, and sometimes stop after a few moments.
The utilisation doesn't appear to show any wild spikes and all seems fairly consistent.
I've updated my bios, drivers, and even done a fresh Windows 11 install

The issue was not present on my old system (Auros B450, Ryzen 2600X, 16GB of DDR4)

I'm leaning toward it being a PSU issue but thought I'd get some opinions.

Any ideas?

Cheers

Welcome to the forums, newcomer!

PSU: Corsair 750M
Corsair is the brand of the PSU while 750W is the advertised wattage of the unit. Can you please state the model for the unit?

How old is it?

 

[ozzie86_uk]

Think I bought it as a gold rated refurb back in 2019. Everything else is brand new.

CXM are bronze rated units, and the 750w models were not very good quality, even the grey label ones. The 750w and higher was a refresh of the older junk orange labeled model, with a few component upgrades.

Your response would seem to suggest you agree that the PSU would be a likely culprit.
Any recommendations for anything that will be a decent replacement without breaking the bank?

Thanks

Thank you very much for the responses all.
Confirmed my theories and I appreciate your time.
I've got a PSU on order, so I'll be wrist deep in cable management in a day or so.
