I have asus rog strix b550-f gaming (wi-fi) mb, it have 24pin (and on the side additional 8 and 4 pin power), on the psu i sent to exchange (corsair-rm750i) was 18pin+10pin on psu itself, and single cable with 24pin connector to mb and 18pin+10pin to psu, my old psu came with just single connector cable in to mb and psu. My new ordered psu cooler-master-v850-gold-v2 are same as corsair, it have 18pin and 10pin on psu, and its cable also like on corsair with  24pin to mb and with 18+10pin on the end that connected to psu.
So my question are: I connect 24pin to mb, and do i need to plug in BOTH (18+10) ends to psu? Also why they made it as two connectors, isn't it easier to have just one ?

Spoiler

 

Gpu tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for Water cooling. Tier A and B for overcloking. Tier C stock and Tier D avoid.

( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)

Spoiler

 

Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.

You didn't mean to use the Corsair cable for the Cooler Master, right?

You can fry M/B. 😇

My bad English 😞

I asked you if you used the Corsair cable for the cooler master PSU.

 

It is only safe to use cables supplied with the PSU or cables that have been verified to be compatible.

The pinout on the PSUs is different, you CANNOT use the one cable for a different brand just because it breaks out into the same cable size on the back, you WILL fry your parts if you use a corsair cable on a non-cosrair PSU. Or am I understanding wrong?

So my question are: I connect 25pin to mb

It's 24pin, not 25

Yes, it won't work otherwise.

The more pins on the connector, the harder it is to unplug it.
A 28 pin connector would be a nightmare to unplug.

You have to have both plugged in.  And they make it two instead of one because it's actually EASIER than just one.

You do realize the higher the number, the thinner the wire, right?

few more questions, normally people say that different psu can't use each other cables, but some companies sell custom cables, and write that they compatible with any psu, how so?

They're more than likely just extensions and not replacement cables.

I'm not actually trying to be as grumpy as it seems.

I will find your mentions of Ikea or Gnome and I will /s post.

https://www.moddiy.com/products/Professional-Tailor-Made-CoolerMaster-Custom-Sleeved-Modular-Cable-Kit.html this one example, just say "all cm psu" and its not extensions.

They don't say that works on all CM PSU. That's why you have to specify your PSU model on the page. They say they make them for all CM psus.

Ok, then what about extension cables?

Because they go from the PSU cables to hardware. They plug into the hardware side of the factory PSU cables, and the hardware side is standardized. Not the PSU side.
