Most Seasonic PSUs have connectors that won't allow that to happen, but an older model like your S12II might not have that feature. Check the PSU manual, and the cables to the CPU power connector and video card power connector.

The PCI-E power cables are labeled as such and are divided 6-2 instead of 4-4 like the CPU power connector. Right now I don't even have the GPU installed since it's quite big and was in the way anyway, as I was trying to figure out what's wrong.

Right now I have connected:

• The 24 pin power connector to the right side of the motherboard, next to the RAM
• The 8 pin (divided into two connectors with 4 pins each) connector to the upper left side of the motherboard, next to the CPU
• Two SATA connectors connected to the Hard Drive and the SSD. Using one for each since it's easier. Also I connected a small (12V iirc) connector from the SATA that leads to the SSD to the hub that controls the chasis fans, as seen in the instructions I followed to build the PC.
  
• The PCI-E connector is currently unused since I have removed the bulky GPU.
• The Floppy Drive Power Connector is unused, as I've mentioned in my previous post.

There are no other cables coming from the PSU.

I've tried all three different cables (HDMI, VGA, DV-I) and selected "Input" each time I changed them but nothing changed. I've connected it to my laptop to check and it works normally. This is the monitor.

I've tried them all, I started with A2, then used A1 for a while, now I have the RAM on A2 again.

I'll check again just to be sure but I think they are connected properly.

It was too late yesterday to try the outside the box build but I will attempt it shortly and I'll let you know what happens.

Thanks a lot!
