I'm currently working on a very tiny build (uSFF gaming rig) and have a power supply that I want to use. Almost all of the specifications line up to what I need, but I was wondering about one thing with regards to the ASRock Z77E-ITX motherboard.
The VRM step down stack which takes the power from the EPS12V and produces the various voltages required for the CPU -- what is the total V-in range that is applicable for this circuit? Most adjustable buck stepdowns that I've worked with have a very wide range of input voltages (such as 0.5VDC up to 40VDC), so I would like to know how large of a range I have to work with on the processor power line with this motherboard :D
If you cannot provide this figure, an alternate way to answer my question would be if you could provide the specification part #'s for the capacitors, inductors, and a circuit diagram; I figure this is probably relatively straightforward to determine from a scan of the board, but wanted to get it straight from the experts :)
Thank you in advance!
