desktop won't start at all

[associates]

Hi,

I was wondering if i can get some assistance from you with my desktop computer. I have just finished building up my desktop from scratch for the first time. When i pushed the power button, nothing happen. I did not hear the power supply running nor did i see any LED lights on on the front panel.  I have checked all my connectors on the motherboard. I am sure it's plugged with power cord at the back of it. Wonder if anyone would be kind to give me some guidance here as to what really causes it not to run at all.

Thank you in advance

You may have not connected the on/off switch to the board correctly.. Be sure it is connected to the correct set of pins on the mboard.   And be sure the hard switch on back of the psu is in the "on" position..

I have just finished building up my desktop from scratch for the first time.

If you already tried plugging into another outlet I would say the PSU or motherboard is bad, assuming you got the cabling connected right

Could you post some info. on what you put together:

1. PSU Make, model, & wattage, Motherboard  Make/model, CPU make/model, graphics card, drives, HDD...  list everything...

Is everything new?  Or is some stuff new and some stuff old?
