Hi everyone I'm new to pc building. I have an msi b350m gaming pro motherboard and can't completely figure out which way the headers go. The manual is confusing me. Any help would be appreciated!
Depending on what your case is, you should have the following basic front panel cables coming out of it:
For reference, here is your motherboard:
The first 5 small cables in the photo above, i.e., the "
RESET SW" (2-pin), the "
POWER LED-" (1-pin), the "
POWER LED+" (1-pin), the "
POWER SW" (2-pin), and the "
H.D.D. LED" (2-pin), will all be connected to your motherboards Front Panel Header (a 9-pin header), which is lablled as "
JFP1", found
near the bottom-right corner of your motherboard (just beneath the screw mounting hole).
The "
JFP1" header, with 9 total pins, is laid out like this:
[o][o][o][o][x]
[o][o][o][o][o]
*
where [x]
means no pin
You would then plug those 5 small cables this way:
POWER LED + |
POWER LED - -->
[o][o][o][o][x] <--
POWER SW (+/- orientation doesn't matter)
H.D.D. LED (+ at
left; - at
right) -->
[o][o][o][o][o] <--
RESET SW (+/- orientation doesn't matter)
The last pin (right-most at bottom) is left unplugged.
Next is the mid-sized cable marked "
USB" (9-pin). This is used to connect your case's USB2.0 front panel ports. The cable is connected on your motherboard's available USB2.0 internal header. Your motherboard has two of these internal headers, labelled as "
JUSB1" and "
JUSB2", both are
located along the bottom-middle edge of your motherboard. You can choose whichever header you prefer to plug the 9-pin USB cable into. The cable only goes in one way, so, check the orientation of the 9-pin socket against the 9-pin header so you won't break any pins.
The largest of the cables (usually not marked) in the photo above is the
USB3.0 (19-pin) cable, used to connect your case's USB3.0 front panel ports. This cable is connected on your motherboard's USB3.0 internal header (also a 19-pin header). Your motherboard only has one, labelled as "
JUSB3",
located just between the JUSB2 (USB2.0) internal header and the JFP1 (Front Panel) header mentioned above. The cable also only goes in one way, so, check the orientation of the 19-pin socket against the 19-pin header so you won't break any pins.
The last of the cables in the photo above is a mid-sized cable, labelled "
HD AUDIO" (9-pin). This is used to connect your case's Audio Jack and Mic Jack. This cable is connected to your motherboard's HD Audio header, labelled as "
JAUD1", which is
located at the extreme bottom left corner of your board. The cable only goes in one way, so, check the orientation of the 9-pin socket against the 9-pin header so you won't break any pins.
