Look for a 9-pin block labeled , usually at the bottom-right corner of the board. Pins 6 and 8 are for the power switch (no polarity). Page 21 of the manual has a full diagram.
If you are looking for the manual to check compatibility or headers, here are the essential technical details for this board: ⚙️ Processor & Chipset LGA 1156 Chipset: Intel H57 Express
: A comprehensive MS-7613 V1.1 Diagram is available on Scribd , showing the block diagram and device map.
The motherboard is an OEM board manufactured by MSI for HP and Compaq desktop PCs. Because it is an OEM product, a standard retail MSI manual does not exist; instead, technical documentation and setup guides are provided through HP Support . Official Manual & Specification Links
: LGA 1156, supporting Intel Core i3, i5, and i7 (Lynnfield and Clarkdale cores). : 4 DDR3 DIMM slots supporting up to
: Supports PC3-10600 (1333MHz) and PC3-8500 (1066MHz).
In conclusion, the missing manual link for the MS-7613 ver 1.1 is not an anomaly but a symptom of a broader digital ephemerality in the hardware lifecycle. It reminds us that not all technical knowledge is equally preserved. For the enthusiast keeping a 2008-era desktop alive for legacy gaming or industrial control, the absence forces a shift from passive consumption (downloading a manual) to active reconstruction (probing voltages, tracing circuits, and consulting forums). The true "manual link" for such a board is not a URL but a methodology: identify the OEM, leverage community archives, and accept that some blueprints were never meant for public eyes. In rescuing these orphaned components, we become not just users, but custodians of computing history.
