Big thing, do NOT mix any of the psu cables.

I watched one tutorial before I changed mine, thinking it was going to be more complicated than it really was. I purchased a fully modular power supply, so it was really easy. All you have to really do, is remember where all the cables where which you unplugged from your original power supply. If you want, you could theoretically take photos of these.

I only had to remove 3 cables from my computer.

1-the main motherboard connector - the 24 pin power cable plugged into the motherboard
2 - the CPU cable - located on the motherboard close to the CPU
3 - One sata cable

You will probably also have at minimum a cable for your GPU, but I didn't.

So basically, probably just watch one or two PSU changing videos, ideally based on your motherboard, then just give it a shot. As long as you take photos or even just remember which cables you removed and from where, you should be good to go. It's not as difficult as it first seems.

In many ways it’s like legos. Watch a few videos and when you change the power supply, make sure you don’t leave any of the old power supply cables in there. Just follow some of the guides and watch how things are labeled. Also don’t force things. Usually things only go in one way.

No!
If you replace PSU, then you also have to replace ALL modular PSU cables.

Modular PSU cables are not compatible between different PSU models.
Using wrong modular cables will damage/kill hardware connected.

Exactly! ALL cables from your original power supply MUST be removedbe. Otherwise as the person above said you can kill parts, which is an expensive lesson to save 5 minutes.

You're correct. Sorry if my original response was unclear

I meant, I originally expected more cables to be connected to my power supply, but in reality, I only had to disconnect 3 cables to remove it. I originally had a non modular PSU so it looked overwhelming at first, but most of them weren't in use.
