Electrical Flash on Startup?

Ever plugged in a power cable to a wall outlet and seen a white electrical light emit from the wall?

 

Yeah, I saw that in my case when I pushed the power button for the first time.

 

 

Has anyone ever seen this behavior before? Is it normal or plausible? I just checked posting, and I don't know if I got a solid post because I used a TV and don't have a graphics card installed. I had no trouble with ESD during the build, so nothing should fail. I mean, the CPU fan and PSU fan spun up as normal. Should I expect no problems or a botched component set?

 

any experience or opinions greatly appreciated.

 

 

Part list:

- Ryzen 5 1600

- Wraith Spire cooler

- Gigabyte AB350 Gaming 3 mobo

- 2x8 GB G.Skill DDR4 3200 RAM

- EVGA 650W G1 PSU

- Crucial MX500 500GB SSD

it's fine, your system has no charge at all, which in contrast makes the electric potential on the socket's side seem much higher. That's what causes a flash.

I thought it seemed normal. I literally did everything right. Good to hear a sensible electrical explanation for it, I couldn't find any articles about something similar. @Krytronixs I do have some unconnected VGA cables from my PSU to nothing because I haven't bought a GPU yet, but all cables are in and locked. Good idea to recheck, though.

Thats from the inrush current for the filtering caps.  Leave the switch on the PSU OFF when plugging it into the wall/power cord in order for it not to happen again.  If the PSU has no physical switch you could turn off the powerstrip until everything it plugged in or just not worry about it.

@KarathKasun I had the switch off during plug-in, the flash happened after that switch was turned on and the power button was pushed.

At worst its a cheapo wall outlet.  At best it just had a bit of oxide on the contacts in the plug.  It only did this once, correct?

@KarathKasun I've seen it with electrical stuff in general before. Actually, just plugging something into the wall earlier, the outlet sparked onto the plug briefly. When something stays plugged in, though, it never does it, so I think the above theory holds.

Was the flash in the wall outlet, or literally in your case?

 

If in the case this is not normal or good and you need to check your connections.
