The 24 pin ATX cable and the SATA and Peripheral Power cables are the same in KM2 and KM3 - although SATA and PP are black ribbon cables in KM3 - so it's only the CPU and PCIE cables that are different. The split, 4/4 version of the CPU cable in KM2 looks the same but the 12 Volt and Ground wires are switched in the KM3 version and these are definitely not interchangeable.

Maybe, if you can spare a moment of your time, you can help with my issue. I have the PSU connected to a powerstrip with indipendent switches. Sometimes, and It's been happening for the past few months, when I hit the main switch and then try to power up the PC nothing happens. If I turn the PSU on and of from its indipendent switch, and sometimes I have to do it two or three times, then the PC would start by itself and go along as if there isn't any kind of problem. I'm quite certain the PSU is about to fail but I'm afraid I could damage some components doing so until unavoidable death will finally come. The only thing left to try is to plug the PSU cable directly to the wall socket but I recently threw the old powerstrip into the bin and bought a better one so I doubt this can resolve the problem. Also it's still under warranty until November but can't do without PC waiting for Seasonic to RMA the component. Hope I made myself clear enough. Thanks a lot for yout time. Best regards.

Have you tried a different cable from the powerstrip to the PSU? It sounds like a fracture gradually being worn in a multi-strand cable.

It's one the few other experiments I'm about to try. Gonna buy a new cable today and give it a few days. Hope you're right about that. Will let you know. Thanks a lot for your help.

There used to be cables like that for kettles and other domestic appliances. You may have one to try that you can swap with it.

@ZazzaZ My 750 was doing the same thing after exactly one year of use. It is failing but Seasonic stood by their product. I would rma that thing. Took only six days to get mine back. They just sent me a new one.Was a simple process but I understand not wanting to be without your pc.


Guess I should get off my lazy butt and take a pic of the several x-series I own so I can be added to the list.

While I am here. How hard is it to completely disassemble a 850 or 750 for paint or powdercoat?

Found a cable at work. Tried it with same ending. Instead of switching the powerstrip on and off I hit the PSU switch. Took me three times before it powered the PC on. Still I'm having some doubts about the PSU being the cause. Could be the mobo, even if I don't think it is since the system is stable even if stressed. Could it be the one of the PSU cables ? Could it be a microscopic grain of dust hidden somewhere even if I recently dismantled and cleaned the PC ? Wish I had a spare PSU...

All I can say is you described the exact problem I had. Swapped it out for my spare psu and the problem mediately vanished. RMA the psu and the returned new psu has no problem. This was my experience, troubleshooting and solution to the problem.
