I am new to building computers and am currently attempting to build a gaming computer, I've done quite a bit of research and have ordered all of my components. I started putting it together today and all seemed to be going well until I came to the power supply. First we plugged the CPU into the motherboard followed by the heatsink/fan. Then plugged our two memory sticks into the corresponding blue slots. Next we mounted our motherboard and then were advised to attempt a boot at this point to see if everything was ok so far. My basic problem right now is the CPU fan will not spin and there is no display on the monitor. The only way I know power is being given at all is by the three LED lights on my motherboard. There was quite a bit of confusion when we began plugging in the PSU. We are using a XFX Core Edition PRO750W (P1-750S-NLB9) 750W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply. I found and plugged in my PSU to the 24 pin connector, however when it came to the 8 (or 4?) pin connector near the CPU I believe I have hit a wall on my comprehension. My motherboard is a ASUS P8Z77-V LK LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS that has two 4 pin connectors near the CPU (labeled by these connectors is EATX12v). My PSU pins match the first four connectors just fine (square pin, circularish pin, square pin, circularlish pin), however the other four pins on my motherboard continue in the same fashion, square, circle, square circle. The other four pins on my PSU do not, they are all the circularish pin. This allows me to only connect my PSU to four of the eight possible connector pins on my motherboard (If I am going only by an exact pin match). So this power supply to motherboard scenario has me a bit flustered. Is it ok to only have four out of the eight plugged in with an EATX12v? The 24 pin went in just fine. Could this be the reason I can't boot and the fan won't run? All of these confusions have me calling it a night, and hoping for answers. :banghead: Thanks for any help I can get. Below is the entirety of my hopeful build.
