is my Corsair ax 850 dead ?

[Gorchau]

Hi there. New user here. I've had some troubles with my pc lately. Shutting down at random. Heat and voltage seem fine when i check them with various programs. Never get bsod or error of any kind. Just a swift poweroff. I cant turn back on unless i reconnect powercord to psu and in some cases it will start by itself when doing so. I had a look inside the psu and i notice some light blue paste/glue/liquid/ ?? ( hard to make out) at least not the same as the white thermal thingie they use. Its between the 2 large round things (capacitators i think) and im wondering if thats normal. if not, could this be the cause of these random shutdowns ? I dont have any spare psu atm. to test with. But would like a second oppinion before spending $ on parts

Hi, I guess that the power supply is under warranty. I suggest contacting the retailer.

It is under warranty.. but the shipping cost for return is a bit high. Might as well buy a new one if the conclusion its dead

 

[alexoiu]

Hard to conclude without testing a different one. Does it shut down under load (when gaming, or randomly)? What motherboard, CPU and graphics card using?

 

[Gorchau]

The shutdown is random. Can be 8 hours or 10 min.. load or idle.
Mb : Asus p8z77-v deluxe
cpu: i7 3770k 3.5Ghz
gpu: Asus GTX 690 -4GD5

Can you reinstall Windows (for ruling out a software issue) and not update it, just install the drivers on the motherboard and graphics card DVDs (no updates), some programs you use and test for a while?
However "I cant turn back on unless i reconnect powercord to psu and in some cases it will start by itself when doing so" points to a hardware issue, either motherboard or power supply, I'd say.

 

[Gorchau]

I can do that. But i seems weird that i wouldnt get bsod or any other error if software is the issue.

Have u seen that before mentioned blue stuff in a psu before ?

 

[alexoiu]

No, but few users look inside a power supply when issues encountered. Most of them prefer to simply return the product.
You can try comparing it to images on Google:

I like to work things out for myself 😉 Guess i will try and find another psu for testing or another pc i can try my psu in. Thanx for suggestions

 

[alexoiu]

No problem. Please post back the result.

on that pic u linked to,u can see the two brown, round ones in the bottom. Between those 2 is where i found that blue stuff at the "floor" where they are seated

 

[Gorchau]

Can you post a picture?

 

[Gorchau]

I tried gettin a photo of it but not enough light To make it clear. I can try again tmrw when sun is still up

 

[alexoiu]

ok, no problem.

 

[Gorchau]

Ok.. got a picture now. Not as good as i'd like but cant do better wo breaking warranty seal. Ho do i upload it ?

 

[Gorchau]

Ok... finally put the psu in another pc. i had a shutdown short after.. stall then shutdown. Tried to duplicate with no luck. (Didnt try too hard) but then shut off computer manually and it wouldnt turn back on. Had to replug powercord like before and the pc would start by itself. Tried a second outlet to be sure.. same thing.
So my conclusion is that my psu is indeed faulty.
Thamx for ur time

 

[alexoiu]

No problem.
