The back side shows how clean and organized this Thermaltake Power Station PSU is.
We see the the main power lead that connects to the main distribution box, next (outer right) to it there are two 6-pin PCI-Express graphics card connectors. Located to your left is a 24 pin mainboard connector which includes the "older" 20-pin power socket and additional 4-pin socket which was introduced with PCI-Express mainboards.

I told ya matey ... it is supposed to be SLI compatible. The sticker also clearly shows the two 12 volt rails.

One cable from your PSU will go to this little device, the PST. This main distribution box (PST module) fits into one of your 5.25 inch drive bays and on it's front side it'll show voltage activity with the help of with three LEDs. This was the one disappointment as I simply do not like the style of this box when you look at it. I don't want a drive with shouty letters that roar "Power Station" and then see three cheap LEDS on top of it. It just doesn't feel right for me. Taste differ though .. you might go wild right now for all I know. ;)

However, this is a clever little box .. let me show you the backside, various power lead connectors. To your left is the main power connector that hooks up to the PSU. Then you have six 4-pin "Molex" connectors and to the right two 4-pin floppy drive connectors. At the bottom are the four SATA power connectors.
