Hi Everyone,

I recently made the noob mistake of plugging a fourth GPU into my MSI mobo....

 and I fried my Corsair PSU and melted part of the 24 pin connector on the MOBO. 

I found the replacement MOLEX part from Mouser and have my old mobo ready for testing. 

Since I couldn't watch my GPUs wait for the mobo repair - I bought a replacement mobo (socket FM1) last week for $100.  Since I'm already in way over my head on mining rigs, I was thinking about returning the temp mobo.  Still, it was fairly difficult to find an FM1 socket board with enough PCIe slots - so my question is:

Do you think I should just keep the board for backup parts?  I wont make the same stupid mistake again (I bought MOLEX PCIe-extender cables on ebay), but part of me wants to keep the temp mobo for backup parts...

Do motherboards often die?  I've never lost a motherboard, but I've had every other component die.  My repaired mobo is an MSI military grade A75A-something.

Your opinions are appreciated.

*****NOTE:  I RMA'ed my Corsair PSU (TX650) and they sent me a new one for free!  No questions asked!  If you have a choice - go with Corsair they are the shit!
