Just finished a new build, however there seems to be no power running. There are 0 signs of any power. psu does not make a sound, no led lights on mobo or fans spinning, no sounds also. I have both power cables plugged into motherboard as well as everything else plugged into power supply. I'm guessing its a power supply issue however I'm not really sure. If anyone could offer some advice I would appreciate it.

Did you turn the PSU switch in the back to 'ON' ?

You could check your outlet to make sure it has power.

Does the PSU fan come on? If not, I would suspect a DOA PSU. Did you try the paperclip trick on the PSU to test it?

sounds to me PSU may be dead. I know this sounds noob but check that both ends of the power cord are seated right and powerstrip/lightswitch on the wall is on. Other than that if you verified not even the psu fan is spinning then time to RMA

i did not, wanted suggestions before taking it out, and the psu fan does not come on.

Is the power switch on the case hooked up right?

Try to override the power on the motherboard by touching the two connectors with a screwdriver.

Well it could be bad. You should try and power up by touching the connectors on the motherboard with a screwdriver.

Do you know what I mean by that?

That would eliminate the power button as the problem.

Afraid I do not know that trick.

The two pins on the motherboard where you hook your case's power button to. Should be a plus and minus. Unplug the case power button and take a flat head screwdriver and touch the two leads together for a second. That does the same thing as your case switch does.

Did you say you tried to power on the PSU with the paperclip trick to check it? Your problem could be the motherboard as well.

the asus mb should have a green power led with no cpu installed or ram.you can flash the bios using the bios flash back and no cpu. if the power supply turns on with the green wire check for dead shorts..missing standoffs or bent pins on the cpu/mb.
