Am I Supposed to Use All My PSU Cables?

Building my first PC and PSU is completely modular.

For my specific build do I need to plug in every cable into my PSU?

If not, do I just keep those cables to the side and leave those spaces empty on the PSU box?

What cables do I need anyways for my build that I should plug into the PSU?

Also, I want to test all my parts, but I realized I didn't have a power button so how would I even turn on the PC? Reason I'm trying to test all my parts is because my case came broke so I'm gonna need to wait like 2 weeks for a replacement.

Thanks!

No, you have a modular PSU. The benefit of a modular PSU is you don't' have to plug in the extra cables you don't use, so that way they aren't in the way.

You should need the main 24-pin cable, 1 CPU cable, 1 or 2 PCI-E cables (just 1 for one GPU), 1 SATA cable, and maybe 1 molex if you have any molex to connect.

Here's how to start your system without a power switch.

Only use the cables you need. Save the remaining cables in case you need them later. Look up some guides for first time pc builders from reputable youtubers like GamersNexus, Jayz2Cents, Paul’s Hardware, LinusTechTips. Starter tip: you don’t need the case at first anyway - build the system on a non-conductive surface to test all the parts since it can be a pain to troubleshoot after everything is installed in the case. The motherboard has a header (connector with pins sticking up from the board) that includes connections for the power switch on your case. Check your motherboard manual to find the two pins on the motherboard that you need to jump in order to power it up.

Thanks, but how do I know which cables I need to plug in.

MoBo is obvious, I have an HDD, SSD, and optical drive so I'll need at least 2 SATA slots out of the 4.

I think there's a PCIe power slot or something for the GPU. Idk what i need to plug in. Also, for my MoBo, are all those super tiny cables that are like at the very bottom of the MoBo only from the case?

I updated my original post to tell which cables to use.

Damn, I got ninja’d!

Yes, those super tiny ones are usually only from the case. Sometimes a fancy extra part like RGB CPU cooler or something has a USB or RGB cable to plug in down there.
