Hi gents. Seriously need help. I assembled my system, followed the manuals to the letter. All I get is a green light on the mobo itself. System doesn't turn on. Here is my build:

Intel i5-3330 3.0
Asus H61M-E Mobo
Kingston 4gb 1066 RAM
Toshiba 500GB HDD
Zotac GTX 950 OC 2GB DDR5
Seasonic S12II 80+ Bronze 620W
Cooler Master N400 tower

Thanks in advance.

Seeing as it won't turn on at all, It would have to mean that some important part of the system isn't getting power.
Looking at the pictures I don't see anything immediately wrong, but I would recommend taking every power plug completely off and re-plugging them. (24pin and CPU power most importantly)
Also, this isn't the reason it's not turning on, but you should try and get the CPU power cable off of the CPU fan. It might get caught there.

I don't know how the stand offs are under the motherboard, but I would take the mobo out and put it in properly. If it's not properly fastened it might short out if the bottom of it touches anything conductive.
You might also try to put the RAM in the other slot, in case the first one is broken...

Does it make any beeping noises? (error codes)
Are you sure all the parts are functioning?
What happens when you press the power button? Do the fans spin?
Is the monitor plugged in properly? Does anything at all flash on the screen when you turn the PC on, or does it stay completely black?

Okay... are you absolutely sure the power switch is plugged in the correct place?
Make sure the CPU and RAM is properly placed.
Maybe try resetting BIOS (there's a circular battery in the mobo, take that out and wait 30seconds or so, then put it back)

Without seeing the system there isn't much else I can think of right now.

Just to make sure there isn't anything wrong with the power switch, try and take the power switch off of the motherboard and then take something conductive and connect the two spikes that are for the power switch (that should turn it on). Be careful not to short out anything else. If still nothing happens, we can at least rule out the power switch.

just putting this here.... (PWR_BTN being the power switch)

Thanks for the help! I finally figured it out. The PSU has connectors for the case fans, so I connected them. And then I connected those connections to the Chassis Fan pins on the board... Hahaha. So I took that out and voila! Finally got it to work. Damn Seasonic runs so quiet I didn't even know it was on! Thanks again!
