problem with new psu

[stevieg]

hi im new to all this building/modding stuff and i was wondering if you would answer a few questions for me.
ive bought a new case and power supply seperately and i just today put them together to see what the lights/led fans look like together,but the problem im having is that they arent lighting up/blowing is this normal,does the power supply have to be connected up to the motherboard(which it isnt) for it to work,
ive tried the fans/lights with a seperate molex connector from my old pc and they work so im guessing i have a faulty psu(im hoping its not as it just arrived today)
