Nevermind I figured out what I did wrong I had the PCI power plugged in to the 4 pin power slot rather than the CPU power and another minor mistake lol good job me

I purchased all of the parts for the $300 system and have built it but when I try to turn it on the power light flashes then nothing happens I have a monitor and PS2 keyboard plugged in and I’m pretty sure I plugged everything in right, any suggestions? and yes, I am sure the case is plugged in to the motherboard…
