Molex Cable

I have a newly built tower.
Gigabyte GA-MA770T-UD3P Motherboard AM3, Thermaltake Toughpower XT 875W PSU with a Sata Western Digital Caviar Black 1TB Harddrive.
In my old Dual Core tower, I had 1 x 320GB Sata HD, and 160GB IDE HD (the 160 was used for backup purposes).
So I took the 160 IDE out of my old tower, plugged it into the board, I had some trouble locating a molex cable, but I found a spare one in my box of goodies.
Plugged in the molex.
So the HD had power and a reader.
On this new PSU, I have noticed that it only has Red and Black connectors.
So anyways I booted up the tower, made sure the motherboard was able to locate new HD's, it didn't find it. I have not changed the jumper settings, as it is the only IDE addon in this tower, I have left is as Master.
Rechecked the cable in the mobo, and the power to the HD and PSU, rebooted still wouldn't find it.
Swapped out the IDE ribbon for a new IDE ribbon, rebooted. It still cannot find it.
So my question (even though I think I know the answer) does the new PSU red and black only cabling have anything to do with it?
The same OS is being used in my new tower as was my old tower, although this should not factor into it.
Oh footnote while I think of it. I had a brand new Sony Floppy Drive installed. The tower could see it, but it wouldn't work at all.

By Red and Black connectors, do you mean just red and black wires going to the molex connector? It sounds as though you are missing the yellow 12V wire which powers the motor on the HDD/FDD (the red supplies the logic circuitry, with the black being the ground).

As far as I'm aware, most PSUs use standardised colour coding for the different voltages that are provided. Black is 0V, or ground. Red = +5V, Yellow = +12V, Orange = + 3.3V.

Red and Black wires are the only thing that are coming out from the molex cables from the PSU, that I can see,

I have a CM Storm Sniper Black Edition Case, which has a heaps of fans, they are all connected using molex cables, the odd thing is there are only the two wires powering them the red and black, I have yet to spot a yellow molex wire in the case.

As for taking a pic of it, omg do you have any idea of how heavy this case is, I am a middle aged woman, so removing it from it's cubby hole, carrying it out to the kitchen (where I can see), is a genuine effort.

Thermaltakes website shows the standard molex cables, but be damned if I can see one in the case.

Looking at the manufacturers website, there are molex connectors supplied with the power supply that should work, the one you are trying to use is probably for a fan.
