DogOfMetal Posted November 20, 2019 Share Posted November 20, 2019 Yes, that title is correct. I've experienced TWO fried Gigabyte Aorus X399 Extreme motherboards using an AX1600i as the PSU. Each one failed after about six months of use. Both failed in the same manner and under minimal usage (at the time of failure). The same component failed on both boards - an electronic component near the AMD X399 chipset IC had a meltdown. I've now switched to an ASRock X399 (Fatal1ty) Professional Gaming MB. Hopefully this one doesn't fail in ~6 months. I'm unsure what type of electronic component fried (resistor?) but I've attached pictures. One of the reasons I chose the Gigabyte board over other X399 TR4 boards was that it has 2x4+4 CPU power connections as opposed to 1x4+4 and 1x4 CPU power connections and I wanted an MB that supported CPUs that may demand more power (like the 2990WX). I wonder now if the board's design is defective and doesn't follow AMD recommendations because it is the only one I found that offers more CPU power input. Anyway, if anyone has had a similar experience or any knowledge they can offer I'd appreciate it. Thanks! Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Notepad Posted November 21, 2019 Corsair Employee Share Posted November 21, 2019 So based on what you said the PSU is not responsible for the failure at all. If the PSU was faulty and was going to fry your motherboard it would not happen after 6 months of use on each board. Instead the failure would be instant if the AX1600i was indeed faulty.

DevBiker Posted November 21, 2019 Share Posted November 21, 2019 I've had a Gigabyte Aorus X399 running a 2950X for a year now with no issues ... on an HX1200i. Did you contact Gigabyte about this? I doubt it's the PSU. Link to comment Share on other sites More sharing options...
solarity Posted November 21, 2019 Share Posted November 21, 2019 It looks like a cracked ceramic capacitor that failed shorted from possible stress from board flex. It isn't a PSU issue. It is strange it happened on two different boards. What case are you using and are all the standoffs the same type and height? Reminds me of this video: [ame] [/ame] I will see if I can pass this on to some guys at Gigabyte that I know. Link to comment Share on other sites More sharing options...
William1 Posted November 21, 2019 Share Posted November 21, 2019 Yup, that is a cap and it is extremely doubtful it was caused by the PSU. Most of the time when they fail, it is because of poor assembly of the board or being undersized/cheap part. Link to comment Share on other sites More sharing options...
4Me2Know Posted November 22, 2019 Share Posted November 22, 2019 (edited) The large hole on the underside should not come from a failed top side cap. Ceramic caps generally fail open (AFAIK). I wonder if it is caused by an over stressed via. The burning may be an arc set up by too little clearance or migration of conductive material. I've seen migration cause that sort of burning in Sata power plugs, had to look it up. The only way that should be in any way related to the supply is if the cap was trying to deal with horrible ripple or voltage spikes, both I would hope are unlikely on a decent PSU.
