PC shutdowns down and restarts whilst gaming

[robmichaelparker]

Hello, my PC has recentley developed an issue. Whilst gaming and the processor and/or graphics card are (presumably) working hard, my PC suddenly shuts down and restarts. Game is total war warhammer 2 if anyone interested.
Upon reset i get a message that "asus anti-surge was triggered to protect system from unstable power supply unit".
Ive tried different plugs in the house without plug extension (no shutdown), with extension (shutdown). It was suggested to replace the plug extension with a high end one (shutdown), and ive replaced the PSU with a like for like unit (shutdown). The PC runs normally when not gaming, and on less demanding games (Crusader Kings 2). Ive run a high demand game whilst using open hardware monitor and didnt see anything overheating. Anyone have any ideas?

PC was brought 2 and half years ago. Had the above issue once maybe 6-12 months ago, i changed plug sockets and PC worked fine after.

Intel Core 17 6700 (Skylake) 3.40 GHz
Nvidia GeForce GTX 980 4MB
x2 8GB Ram (Kingston Hyper)
Asus h110m-d D3 motherboard
old and new PSUs are Corsair vs550

Well if you aren't experiencing the issue when your pc is plugged in with no plug extension then its most likely to do with the plug extension/adaptor or your actual house's wiring. Is it an older building?

it is a older building, no idea about the wiring, but the plugs were inspected a few months ago.

To clarify, i tried setting up the PC in my kitchen and plugged direct into the socket, no shutdowns.
kitchen with extension, shutdowns.
In my bedroom in the usual plug socket ive had shutdowns with both direct plug-in and when using an extension.

Ive be speaking to a chap at PCSpecialist (who put built the PC) and he suggested the high end plug extension.

Hopefully some of the more experienced members can chime in but if the issue occurs at your bedroom regardless it could be inconsistent voltage being delivered through the outlet. I'm not sure if a better PSU with better ripple control would help. Another option I guess, if it is a power delivery issue, would be having a UPS but thats a whole other can of worms.

the thing i dont get about the issue being envioenmental/power supply from the socket, is why it only happens when im playing demanding games.

When you put your system under stress its' power draw increases. Your power supply should be ample for your system and the fact that you have replaced it already kind of eliminates it as a cause imo. Perhaps for what ever reason your outlet is not supplying sufficient power to your system but then again I am only speculating.
