They make a 24 pin to 18 pin adapter cable, but I've never seen an 18 pin to 24 pin adapter cable. I've also never seen an adapter cable to go from that style of EPS 12v CPU power (Your 8 pin) to the standard style 4+4 pin EPS connector so the answer is almost certainly no, you can't use that power supply with a standard motherboard AND I'm pretty sure you wouldn't want to anyhow. If you are going to spend the money on new hardware, then make the investment in a decent power supply to protect that investment rather than using an already old and probably not terrific quality to begin with, power supply.

Ty for replay but there no even moded way to change that cable and the problem is the memory cable but beside it written mem cpu pwr so does it provide 12 v or not ?

Yes, it does. That is the 8 pin EPS 12v power cable that supplies auxiliary power to the CPU. The memory controller is in the CPU so by proxy it also supplies additional power for the memory circuit as well. The problem is not JUST that cable though. There are adapters to use a standard power supply with that motherboard, but there are NOT adapters to use that power supply with a standard motherboard. If you want to ditch that motherboard you are going to need to get a different power supply and probably also a different case because it looks like possibly that motherboard uses a proprietary form factor and standard motherboard form factors may not fit into that chassis.

That will not work with your power supply. That is for a different type of configuration, and is for use SPECIFICALLY with certain models of Seasonic and Corsair power supplies. The pinout and most probably even the "keys" on each individual wires plug shape at the end of each wire where it plugs in, will not be the same. If you use that, and I'm not saying you even COULD because most likely it would never plug in, you would almost 100% certainly fry something or everything. Abandon the idea, those workstation HP power supplies are NOT EVER MEANT to be used with anything other than what they came with or another of HP's proprietary boards.

And if you don't understand what "pinout" means, then you REALLY need to do some research. Often, plugs can LOOK the same, and even plug into a similar socket, but the wiring going to each specific "pin" are not the same from model to model and brand to brand. Plugging something into something with a different pinout is a guarantee to let the magic smoke out.
