I am building a new PC, I just got my motherboard in the mail today. It is a ASRock X58 Extreme 3.
I am reading over the manual for it and one of the jumpers says this.
There is a 3 pin jumper labeled 1 2 3, with pins 1 and 2 shorted by default it is "+5v"
If I manually change it to short jumper pins 2 and 3 instead of 1 and 2 then it will be "+5vSB (standby) for PS/2 or USB wake up events.
So I am confused as to exactly what this is for. Can someone explain what it means, why I would want one other the other?
A link to the manual and an actual jumper name (JPxx) would be useful. – Ignacio Vazquez-Abrams – 2010-04-15T00:02:09.117
There is an PDF manual located here for it http://www.asrock.com/mb/manual.asp?Model=X58%20Extreme3 and the jumper is called PS2_USB_PWR1 Jumper
