Discussion Would you re-use a PSU after discovering a melted connector (cable side)?

[mishmash]

Hello everyone,

I suppose I have myself to blame for this - clearly the termination was imperfect. See pic below - I discovered a melted connector on my SFF watercooled cravo, pins correspond to +12V. I suppose it can be due to either:

• HDPlex GAN PSU issues (unlikely, I have another PSU like this in a 24/7 server application)
• Significant power draw on motherboard 12V headers - possible, there is a water pump, fan controller, and shunted A2000 on the PCIe slot
• Imperfect termination - highly likely, the other 12V pins show no damage

My question is - the damage was present on the 24 pin connector on PSU side. Would you consider it safe to re-use this GAN PSU? Or it's destined for the scrap heap?

Thanks!

I'd replace the cable for sure, but the PSU is likely AOK.

How's the socket look?

Second @thewizzard1's comment unless there's damage on the GaN side.
Replace the cable, do some basic tests with a multimeter if you're able, then a non-valuable motherboard if you have one.

If it were mine, I'd swap the cable over and get straight back into it, with my fingers crossed

There is a small scorch mark (or melted plastic?) on one of the 12V pins. But the pin appears to be intact, and is not broken.
