EVGA PSU lit my house on fire! ?

 Share

Does anyone have any idea why my 1 year old EVGA 450W power supply went up in flames while my computer was in sleep mode?

If it helps the specs of the computer was: 

-asus rog strip b450-f mother board 

-1050 TI graphics card

-gen 2 ryzen 3 cpu

-16g ripjaw 3200 ddr4

- Corsair 460x RGB

-all stock coolers, nothing fancy, nothing overclocked

 

BTW the computer ran fine for 3 months before the fire

I want to build another PC id just like to know why this happened and if I should be worried about building another pc or buying a prebuilt. (used LTT videos for instruction on building)IMG_2131.thumb.jpeg.9e7cff1bac505eb5f16545389b6e5756.jpeg

how do you know it was the PSU and not another component?

 

also you should get your breakers checked out, if that was a short it should have tripped the breakers.

some of the lower end EVGA PSUs are pretty crappy with the protections, but really tell EVGA and your insurance company

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...

Which EVGA 450W model? They have a few different ones, some are rather low quality.

 

As for switching to prebuilts, that's not going to help your chances. One of the places they like to cut costs is on the power supply, increasing the risk of problems.

My guess is a component on the high voltage side of your power supply failed shorted (normal behavior being to fail as if it's no longer in the circuit) overheating and eventually going up in flames.

Can't tell from the picture but based on the dark area, it feels like the mains cable also burnt out, and the insulation of the mains wires burnt out as well.

 

Your power supply is in a metal case, so the fire should not expand to the rest of the case normally, unless it went through the modular connectors.

 

// components that could have failed  ... the mains filtering components like X2 capacitors, common mode chokes, main capacitor,  diode or mosfet involved in active pfc circuit (if psu has any)

the entire cable connecting the PSU to the wall was burnt to a crisp

You don't use a surge protector?

I have 3 EVGA PSUs running in my house, which 450W model did you have fail?

i9-10900K, Asus ROG STRIX Z590-E Gaming WiFi, Asus TUF RTX3080, 32GB G.Skill 3200MHz CL14

Samsung 970 EVO Plus 1TB, EVGA Supernova 850W G3, Asus Xonar DGX

Figured as much. Probably the fuse inside your power supply also failed to blow and protect the mains cable and the copper wire inside the mains cable behaved like the filament of an incandescent bulb, going hot and melting the insulation until the copper wire eventually broke from melting.

Your house fuse should have caught it and trip.

 

Here's an exaggerated example:

Surge protector wouldn't have helped with this. Surge protectors catch spikes and other accidental stuff, not shorts.

It depends on what EVGA model you're looking at.. Their W lineup is shit, All B series but B2 are not what you'd expect, G1 sucks and I forgot is it G2 or G3 that has protection mechanisms that don't work. EVGA might make good graphics cards (aside from the exploding 1070s and 1080s which are most likely a bad batch of capacitors), but their rep in power supplies is full of holes.

Yeah those are the more low-quality ones, still should've caught on fire like that.

That's a pretty low quality PSU.

And one of the reasons to go for a good quality one because stuff like this happening is less probable.

Definitely contact their PR & address the issue , especially if it's under warranty & you have the purchase bill of proof. definitely contact insurance & see if you can get any coverage.
