Had my pc shut down unexpectedly last night and wouldn;t switch back on. Well, the fans and lights would like for one second and then stop.

Unplugged psu mains power lead and reinserted and it worked....for a while.

Decided to check all connections and discovered my 24 pin power connected has melted on one of the yellow wires and two of he sockets on the mobo are brown.

Plugged back in and worked but 12v radings from software are now less than 12vs and can;t over stress the pc as it shuts down but surfing fine.

So is it my mobo or my psu or both which have gone? They are both under warranty still but don;t want to ship both back and have return with no fault showing.

The only thing i can think of to see if the motherboard is gone is to borrow a psu and to see does the pc boot . To me it sounds like the PSU could be gone so i think its time to find out if it has taken anything else out with it . I had a cheap PSU die on me before and i just put the pc in the bin because i thought the whole thing was gone . Was or is there any smell coming off the PSU ??

The psu is one of the best you can buy a Seasonic M12 850W. No smell from it and it;s powering my computer now. Just I cant stress the pc and play games.

Now that could be the psu but also the Asus mobo could have damage as it takes all its power from the 24 pin socket and has no extra molex conenctor unlikt some mobos and I have all pci-e slots occupied.

Oh and if I switch off the psu the mobo looses all of its bios settings. Mobo is only 6 months old so its battery really shouldnt be knackered.
 
looks like that's it. mine looks exactly the same.

why does it go though? I mean If the psu can't supply enough juice then it should just shut down and not melt. all 24 pin sockets have the same wire so worried now my replacements will go the same way.

you reckon both the mobo and psu is a goner then? I was hoping only one.

and I assume chances of warranties is non existent? I mean the psu should be.enough by my calcs and the mobo doesn't say you can't fill all the slots so surely both should get replaced?

To tell you the truth i would just chance my arm and send them off for RMA and see what they say , you might get lucky and get them replaced or they might ask for a small fee to replace them .
 
Id have thought both should be covered by warranty? Kinda got me worried as well as im also on an 850w psu with oc'd 470's, though ive backed the card clocks down to 750mhz from 800 as theyll do 750 on stock volts.

I think it could be all down to the manufacturers of the product , some may offer a replacement while others could say you overloaded the PSU so you broke it .
 
Shouldnt be the case though as my psu should have overloading protection. At the end of the day I have a massive single 12v rail but I do worry about these asus boards taking all that power just through the 24 pin connector to the mobo.

Okay the extra juice needed for the gpus and the cpu are on seperate connectors but I have all my slots occupied and use lots of my usb ports as well. My old gigabyte board had an extra molex connector to supply power to the pci-e slots in addition to the mobo 24 pin connector.

And researching this problem, all the mobo/psu combos where this has happened all seem to have a common factor that it was an Asus mobo.

I am going right off Asus tbh. This current board (P6X58D-E) died within one week the first time and it's brand new replacement from ocuk was DOA. I should have realised then that it wasn;t a good start with this board.

It gets great reviews but I have lost all confidence in it.

Just ordered a Gigabyte GA-X58A-UD5 plus a Corsair AX1200 psu. If I get RMA on the Seasonic and Asus then they can go straight on MM.
