Does it really matter?

I am on my first build and was wondering what the consequences are if you plug in your equipment into the wrong slot on the PSU. For example if one cable is suppose to be connected to the peripheral section but is accidentally plugged into the PCI-E section. I am sure that this matters but I am bit paranoid that I may have done this.

There is a switch on the back of the PSU, is that on? Have you connected the power switch cable that comes from your case into the power switch connection on the motherboard?

Ensure your 4 (or 8) pin CPU power connector on the motherboard has a cable (not a PCIe cable).
This would be the 4+4 CPU slot you mentioned.

A PSU doesn't run at its max rating all the time, it just runs what is required by the components. Most US outlets and plugs are rated for 15 amps, at 120 volts thats about 1800 watts.

I plugged the cpu cable into the slot that says PCI-E and 4+4 CPU. Then I plugged the cable that connects to my SSD to the Periphiral and SATA along with the fans that are on the seperate board.Then the PCI went onto the PCI.

PSU cables are mostly fool proof (mostly). What are you trying to power?

Modern graphics cards are powered via PCIe power connections (8 or 6 pin).

Motherboard power is very fool proof, it is the 24/28 pin long connection.

Modern CPUs require power through the motherboard, they are either a 4 pin, or 8pin connection that differs from PCIe, PCIe power should not be able to fit into this connection but they look quite similar.

Sata drives are powered by unique connections, I doubt your error was here (if there is one). Some fans are also powered by this Sata power connection.

Molex connections, the larger 4 pin connections are used to power older drives, some optical drives, and some case fans, older videocards also use to be powered by molex connections.
