PLEASEE if someone knows for sure

My mobo has 8+4 pin cpu pins
Now what i got in my Power supply is 2 CPU cables of 8pin each, that cannot be divided into 4+4.
Is it ok to connect 1 cpu cable to 8 pin socket and then connect the second 8 pin cable to a 4 pin socket?
So the first 8 pin cable would cover all 8 pin sockets on the mobo, but the second 8 pin cable would cover only 4 pin on the mobo with the other 4 just not cover any pins because the mobo is only 8+4 and my cables are 8+8

Many modern CPU's do not really require even an 8 pin to power them if not overclocking so running with just one 8 pin connector is probably OK. But what motherboard, CPU and PSU do you have?
 
I have z490 Aorus ultra, 10850k and RM850X
hmmm...are you planning on overclocking that beast? I can imagine it would be like a furnace when pushed with an overclock, so it might be a good idea to get a proper connection.

If I understand you right you're saying you only have cables with 8 pin connectors. Check the 8 pin connectors really carefully to see if one doesn't split into two 4 pin segments.

You might also go looking for some other cables for the RM850x. I'm pretty sure my RM650x came with at least one CPU cable that had a 4+4 connector on it. It's OK to connect a 4+4 pin connector to a 4 pin socket, just be sure to use the segment that fits smoothly without forcing. The remaining segment will be left dangling.

If you don't want those extra 4 pins hanging off on the motherboard like that, you can get an extension cable like this that can simply take 4-pin power directly from the 8-pin:

Or you can get an 8-pin extension that can split to 2x 4-pins like this one:

Perfectly fine.

Ummm, what is the source of these cables? The Corsair RMx 850 does not come with any solid eight-pin connectors. On the PSU side, yes, but not on the side that connects to the parts.

1 x ATX 24-PIN (20+4)
2 x EPS/ATX12V 8-PIN (4+4)
6 x PCIe 8-PIN (6+2)
10 x SATA (3 SATA)
8 x PERIPHERAL (4-PIN)
1 x FLOPPY DRIVE ADAPTER (4-PIN)
