Can I use a cable from another power supply?

[xDiVolatilX]

Question is If I need another sata or molex but the one I have is already used can I use one from a different brand power supply? I have extra cables from my PC Power & Cooling 1000w PS that I want to plug in one of its cables to my MSI 1000w PS it's just a simple sata with molex end

Am I ok? Not recommended but will work? Anything to worry about? A cable is a cable? Don't do it you can fry the system?

What can I do?

not generally a good idea, the only way i would is by checking the pin out/test with a multimeter first. or just pick up a sata/molex splitter.

I have splitters but they kinda look ugly. So the wire itself changes the wats transfered? I thought that was the power supplies job? Like how we can use PS cables for monitors?

ok, hide it then. wats?! the external power cord is standardized, the internal cables can be pinned however the oem wants. so dont mix them or test which pin goes where to make sure you dont release any magic blue smoke.

The component end is always going to be the standard pinouts. The issue is that there is no standard for the PSU side. Even if you have a cable from a different PSU that physically fits yours, there isn't any guarantee that it's pinned the same.

If you aren't comfortable with using a multimeter and possibly de-pinning connectors to swap the pins around, I'd just use the splitters. I used to do some custom cabling/sleeving and it's not really that complicated, just a pain in the ass.

If you're tired of your SATA devices working, a quick and sure way to make them stop working is to use a mis-matched PSU cable. I did it by accident once; fortunately for me, the victim was a not-too-expensive small capacity SSD. Fried it right quick.

Thank you to everyone who chimed in I resolve my issue and everything is plugged in properly without using any other cables thank you. This is very good information to know not just for me but anyone else reading this also thanks again.

Just tone out the pins with a multimeter (and repin if necessary).
That's what I did with a 3rd party 12VHPWR cable to use with my eVGA G3 PSU

To be doubly sure, plugged the cable into the PSU, and verified the voltage on each pin with the system on before plugging it into the GPU
