Supermicro PMBus Extension Cable?

[archmagos]

I was wondering if anyone had come across one of these before? I have an a1SAi-2750F motherboard mounted in a Supermicro 826 chassis and the PMBus cable (from the power distribution board) is too short to reach the JPI2C1 header on the motherboard.

I assume I could always make my own by rigging some pins and cables, but the connection onto the motherboard header will be a bit flaky since there won't be a retention clip to hold it in place.

If you were curious what these looked like:

5-pin 4-cable connector on SuperMicro server PSU?

I assume something like this would work but it really seems like overkill for something that needs to be just 15cm to 20cm longer (plus it is only 4 pin, where the PMBus cable is 5-pin with 1 cable NC):

Necro, I know, but also looking for supermicro smbus cable extension, if anyone ever found them for sale.

Mounting uatx SM board in sc846 chassis, and smbus cable is a bit stretched.

Hoping for easy solution before I break out my questionable soldering skills...

I never found one for sale -- I ended up replacing the power distribution board (which was on the list anyway) and that fortunately had a longer PMBUS cable (which effectively solved my problem).

Thanks, will keep the PDB in mind as an option. Mine barely fits for now, but would need extending to use the internal drive trays mounted against pwr supply housing.

Necro again but....I've been looking for this as well as the cable is .5" short to reach the motherboard...doh!

Here's what someone on Reddit came up with for me so I think I'll give it a try:

As a follow-up the list above worked great and I now have PSU information...woot!!!

I did get 12" versions of the wires instead of 6" just because the cost was the same.
