How can I tell if my power supply is on?

[R3d1ynx]

Just build a pc and it won't turn on. All the wires seem to be in place I'm not sure if the power button isn't working or if the power supply isn't

Are you positive that EVERY wire is connected? Including the front panel?

Are you sure that you set the SWITCH on the BACK of the unit to the on position?

I made sure non of the wires on the front panel are loose several times and I tried turning it on using bot sides of the switch on the back

So, in case you don't know, the PSU should be "always on". The button on the case shorts two pins on the motherboard that takes the PC out of standby.

So.... next question.... Does your motherboard have a standby LED on it somewhere? What motherboard is it?
