On the side of the CNC router project (as always) I started an other one. This is clearly just a PC project. Build a NAS from the things I have on hand (ceiling cleanup 😂).
During the long years, I used several - called modular - ATX power supplies. Those things allow you to clean up the cable jungle a bit, what always shown up inside the PC cases, by allowing you to detach unnecessary cables from the PSU. These are the peripheral cables used for the mass storage, graphics cards, etc.
The connectors on the supplies for the modular PSUs are not standardized, usually use the same kind of connector (2 row, 6 or 8 pin, Molex Mini-Fit).
Yes, I bought PSUs from different vendors (Gigabyte, Chieftec, etc.). Yes, I never labeled the cables. And yes, I keep those in one box. This means, I don't have a clue, which cable belong to which PSU.
For the NAS PSU I needed several cables (in hot swap bays, I plan to use 14 disks). If I mix those up, I can imagine the firework it can cause.
The subject currently is a 550W Gigabyte Odin (I also have an 800W somewhere just not found in the ceiling yet). I downloaded the manual of it. It has the connector pinout in question. (Indicated, not to use it as is bad)
I started to starch my head. None of the cables in the box has this pinout.
DMM on. Measure.
My suspicion become true. The manual is garbage.
This is the correct pinout (the connector drawing is from Molex and show the connector on the PSU itself), and it correspond to all of the cables in my box (it is maybe a coincidence, but Gigabyte, and Chieftec use the same pinout):
