Hi. I'm about to build my new desktop today as the hardware comes in the mail, but I really have no clue how to connect the cables/wires once I put them all together. Like for example which plug goes to GPU or SATA and motherboard. Also, when I complete plugging them all in, is there a way to check if I have plugged something in wrong (giving it insufficient power or something)?
The wires - as long as the plug fits into the socket, it's fine. Theirs no requirement of any particular order - except for cable management. (Basically you don't want to clutter your case)
Building a PC is really simple. The green plug goes into the green socket. The blue plug goes into the blue socket. The one with 4 pins goes into the socket with 4 pins. The one with 6 pins goes into the socket with 6 pins.
