In the process of disconnecting the 8-pin supplementary power connector on a MA790X-UD4P board, I broke off the adjacent can-type "transistor". As this component has only two leads and the socket on the board is marked "+" and "-" it has to be a diode of some sort. It is marked "560" with some batch numbers. Now, the board is under warranty (though this clearly was my fault) and I could have sent it in for repair/exchange, but I am an electronics hobbiest and this is ONE LITTLE DIODE; I could replace it if I knew its specs.
So I started emailing to Taiwan, asking for the specs on "560". The replies persistently said to return the board (to their US service dept.). I finally got a (non-free) phone number and talked to a technician, who looked up "560" in his parts inventory and gave me a long obscure number on which Google search could find nothing. Another call, another tech said he COULDN'T POSSIBLY give me the specs: TRADE SECRET! This is nonsense; if there are any "trade secrets" on the board, they are in the integrated circuits.
For comparison I looked at a recent Asus board I have. The semiconductor components retain their original manufacturer's markings and it was easy, as a test, to locate online a pdf spec sheet on a selected component. I could have then ordered a substitute. Gigabyte should provide access to component parts specifications.
How did I solve the problem? I bought a similar model board, used, sold "for parts only", which was populated with many "560"s, removed one and re-soldered it to the MA790X.
Gigabyte uses high-temperature solder, so I had to use a mini rotary drill to drill out the "560". Not as hard as it sounds, and a lot quicker than having to return the board. It works fine now.
