Asrock FM2A75M-ITX Motherboard Fire

post #1 of 181
Thread Starter 
This is being discussed already in the FM2 motherboards thread (http://www.overclock.net/t/1301979/trinity-apu-amd-socket-fm2-motherboard-discussion-gallery/230), but I wanted to draw more attention to the issue, in case anyone else has had a similar issue, or indeed if any Asrock reps are having a look at the forum and want to help us in any way.

There are three of us on that thread who have experienced problems with MOSFET's setting on fire. Here's a picture of mine: http://www.overclock.net/t/1301979/trinity-apu-amd-socket-fm2-motherboard-discussion-gallery/220#post_18799453 and here's a picture of one of the other guys: http://www.overclock.net/t/1301979/trinity-apu-amd-socket-fm2-motherboard-discussion-gallery/200#post_18778199

Has anyone else experienced this or any other problems with this board?

ASRock have always used cheap, old MOSFETS (Or VRM's whichever word you want to use)

I'm not surprised at all that this has happened, this is the one reason I recommend the GA-Z77X-D3H motherboard over the ASRock boards.

I had no idea what a MOSFET was until this happened.

The Z77 boards would be great if I was planning on an intel gaming install, but this was supposed to be an FM2 HTPC install with some sofa gaming. It's in a mini itx case and at the moment, there are no other options out there for FM2 ITX. I see the MSI looks to be the next one to be released, but there are still no real reviews of it out, so rather than potentially get burned (no pun intended) twice, I'd rather wait to get a reliable board. Unless anyone has any suggestions for an FM2 ITX board?

Can you not use an AM3+ board, there are undoubtedly going to be more options for you

I already have the processor - an A10-5800k which was working brilliantly.

That said, if the processor has been killed also, then I probably will want to switch to a different set up.

Well,

The VRM's are linked to the processor quite heavily, it honestly wouldn't surprise me if it damaged that as well..

That's what i am thinking too... but then again it should be ok, since the second the mosfet/s popped the voltage from the PSU would have stopped and the motherboard would have had no power to it. So the CPU may be ok.

I'm going to list this down as failure prone... quite a disappointment, the first ASRock I've seen like this. Mini ITX does limit VRM size and capacity, however.

MOSFETs are part of the VRMs, in fact.

Question here. What was your CPU running speed and voltage, and CPU heatsink?
