[SOLVED] What will die first after many power surges motherboard or power supply?

[Jake0402]

Im just curious if what will be the one who'll die first. Is it given that if the motherboard dies in an power surges the power supply is damaged too?

Specs:
Gigabyte B450 aorus pro wifi
Seasonic S2iii 550W

+cheap Avr "I dont think it has power surge protection"

Why not consider a device to help protect against the surges rather than find out?
What is causing this issue?

Yes, I'm planning on buying power surge protection. Before, my motherboard has blown transistor in it so I returned it to repair, so now I'm curious if my PSU is affected too that's why I am asking if is possible that my PSU died first before the motherboard😊

First thought was maybe motherboard but now thinking it could be either. Understand your thoughts my gpu just died and took me buying extra psu and ram to sort it out. Surge protector money well spent

The blown transistor is near in the front panel port of the motherboard so I think GPU is safe.Yes I think 50% chance I'll RMA PSU and RAM they have 2years warranty

I think if it were a merely logical consideration I guess you could say PSU. However, the ability of the PSU to react to a surge in a way that damages it and/or creates an output outside it design parameters don't have to be mutually exclusive.
There are testers for PSU, perhaps even the shop you are already working with could check it for you. Weigh the cost of the connected parts against the replacement of the PSU (assuming everything else has already been tested as fine) and weigh that expense vs. troubleshoot/replace.

Electricity follows strange pathways.
There is NO way to predict.

Also remember that the surge that affected the PSU>Motherboard>GPU, et al., may also have affected other devices that are plugged into the wall outlet and your PC... like monitor(s), USB devices that has an AC adapter, USB printers, powered speakers, etc.

Electricity will always follow the path of least resistance. That's what these surge suppressors do... give electrical spikes an easy path to ground so your devices downstream are reasonably protected.

Most, if not all AVRs, UPSs, and reputable power strips have this basic protection as long as it is properly Earthed/grounded.

And in my personal case last year, totally irrelevant.

2x HDMI ports on a Denon receiver
1x ethernet port on my main PC
1x ethernet port on my printer.

All devices protected by good quality TrippLite and CyberPower UPS.
PC and printer separated by 2x switches and a router.


The wall plug is NOT the only entranceway.

Ooh Thank you for the knowledge now I know, Buying an power surge protection extension will solve this problem right?, in that extension I will connect all my components(including other devices like printer)

Surge protection in most devices is only 'good' for one strike at rated protection level and then it's not reliable at all.

The problem is as always: when the strike occurs you may not know it's lost effectiveness unless there's an indicator to tell you. And even then, who wants to buy new devices every year?

"Help", not "solve".

Electricity will do what it pleases.

Now that you say that I think I'll buy expensive AVR,
And I think one of the problem is my neighbors who do welding I notice that when they weld our power fluctuate, my cheap avr do tick sound and light bulbs dimming then normal again

But almost everything electronic you have at home, they're all more or less, connected to an outlet and in fact, can pass current from one device to another through Ethernet, USB, audio inputs/outputs, etc. So for the most part, the main source of surges will be via the outlets.

To your point, there's also cable TV/internet, external antennas, sat dishes, DSL, everything that is conductive and is exposed, these are also possible ingress points for surge. Most equipment can deal with typically small surges but would likely not survive a direct or nearby lightning strikes, surge suppressor or not. YMWV.

in my case, it's the gpu and avr that got destroyed.

[SOLVED] - Lightning strike fried my GPU and AVR ?

hi, about 3 days ago.. made the mistake of keeping pc on with internet while a thunderstorm is outside. A loud thunder and the modem's light went out, the monitor went red and the pc went silent. the only "luck" I had is it's my backup pc with an old gpu, a gtx 460 that got fried. Would have...

And for the Twilight Zone moment from that nearby lightning strike....

I have a battery powered laser level.
It was on a tripod, in the middle of an upstairs bedroom.
Hadn't been used or turned on it a week or two.
I went upstairs later...."whats that red glow?"

it was ON.
Static pulse through the air.

Still works fine.
