    There is no on-off switch, therefore the PSU circuit is always "closed" when connected to the mains. So, if the PC doesn't start, your PSU might be faulty

    It's not "normal" but it is not uncommon either. Many Silverstone units lack the on-off switch at the rear of the unit. This is actually a VERY common trend with any power supply made by Enhance. Cooler Master, Rosewill, Silverstone, Antec, EVGA, Thermaltake, & Zalman have all had units made by Enhance that share this common trait.

    If you connected your front panel cables properly, the system should turn on with the press of the power switch on the case. You could alternatively use a small screwdriver to contact the power switch pins on the motherboard to have the system turn on without needing a case or button.

    If your motherboard has power button on it, that should also work.

    If none of these things work, then you should RMA the power supply as it may be faulty.

    Right. You can't turn ANY ATX PSU "on" by simply flipping a switch. The motherboard has to "tell" the PSU to come out of standby. This is done by shorting the power on lead to a ground.
