Hello everyone,
I have had this knockoff 9211-8i HBA that i bought a while ago on ebay, and it had worked rock solid for around 2 years or so.
That is until i decided to clean out my server, and in the process of doing so, I blew out the F1 fuse on my card. I probed with my multimeter to confirm it basically had infinite resistance, and looking on the internet it seems my issue isn't particularly uncommon.
I own soldering/rework station equipment, and i found a thread of someone who replaced their fuse but when i took a look at the fuse under my camera, it seems like it is not the same as everyone elses fuse. Mine is in a much smaller package that everyone elses.
Another interesting thing to note is that the fuse under the microscope doesnt appear to have any type of damage at all. Pretty odd.

My question is, is anyone able to identify a good fuse to replace it with? Am i overthinking this, and should just replace it with any typical smd fuse?
