About VRMs & Mosfets / Motherboard Safety with 125W+ TDP processors - Page 103

post #1021 of 1100
Well since this is a thread dedicated to VRMs, I just have to ask. Is it possible for a VRM to go bad, and cause the ATX12/EPS12 connector to burn up, without the VRM actually looking damaged?

The EPS connector on my now-dead 990XA-UD3 got so hot that it fused itself to my PSU cable, my first thought was oh great, VRM failure. But in honesty, the entire board still looks like brand new, other than the really badly burned EPS socket with attached PSU bits.

Still have no idea where it failed, very silent VRM failure? Because it DEFINITELY failed.

The same thing to me on an old G54. So yeah it was a silent VRM failure.

I posted a picture of it in the Gigabyte 990XA club, that connector was destroyed. At least now I have a little confirmation, odd that it died at 1.408v though frown.gif Would be one thing if it were the board, but it took my PSU with it (well, at least its warranty, and EPS connector). PSU still sort of works, heh.

also can be a faulty PSU (possibly the connector), faulty board (the traces could be shorting), or a number of other things.

but that can happen due to vrm issues.

Well, MSI did not place any "do not burn" warnings on their 970A-G46 phase and while the larger VRM heatsink gave us a hint of a better design we really didn't know anything about what was under there, so I will admit to having had a bit of confidence in this board. This incident cancels it for me.
